NAME

WWW::Mechanize::Chrome - automate the Chrome browser

SYNOPSIS

use Log::Log4perl qw(:easy);
use WWW::Mechanize::Chrome;

Log::Log4perl->easy_init($ERROR);  # Set priority of root logger to ERROR
my $mech = WWW::Mechanize::Chrome->new();
$mech->get('https://google.com');

$mech->eval_in_page('alert("Hello Chrome")');
my $png= $mech->content_as_png();

WWW::Mechanize::Chrome->new %options

my $mech = WWW::Mechanize::Chrome->new();

You can override the class to implement the transport from the outside by setting $ENV{WWW_MECHANIZE_CHROME_TRANSPORT} to the transport class. This is mostly used for testing but can be useful to exclude the underlying websocket implementation(s) as source of bugs.

$mech->add_listener

my $url_loaded = $mech->add_listener('Network.responseReceived', sub {
    my( $info ) = @_;
    warn "Loaded URL "
         . $info->{params}->{response}->{url}
         . ": "
         . $info->{params}->{response}->{status};
    warn "Resource timing: " . Dumper $info->{params}->{response}->{timing};
});

Returns a listener object. If that object is discarded, the listener callback will be removed.

Calling this method in void context croaks.

To see the browser console live from your Perl script, use the following:

my $console = $mech->add_listener('Runtime.consoleAPICalled', sub {
  warn join ", ",
      map { $_->{value} // $_->{description} }
      @{ $_[0]->{params}->{args} };
});

$mech->chrome_version

print $mech->chrome_version;

Returns the version of the Chrome executable that is used. This information needs launching the browser and asking for the version via the network.

$mech->chrome_version_info

print $mech->chrome_version_info->{Browser};

Returns the version information of the Chrome executable and various other APIs of Chrome that the object is connected to.

$mech->driver

my $driver = $mech->driver

Access the Chrome::DevToolsProtocol instance connecting to Chrome.

$mech->tab

my $tab = $mech->tab

Access the tab hash of the Chrome::DevToolsProtocol instance connecting to Chrome. This represents the tab we control.

$mech->allow( %options )

$mech->allow( javascript => 1 );

Allow or disallow execution of Javascript

$mech->emulateNetworkConditions( %options )

# Go offline
$mech->emulateNetworkConditions(
    offline => JSON::PP::true,
    latency => 10, # ms ping
    downloadThroughput => 0, # bytes/s
    uploadThroughput => 0, # bytes/s
    connectionType => 'offline', # cellular2g, cellular3g, cellular4g, bluetooth, ethernet, wifi, wimax, other.
);

$mech->setRequestInterception( @patterns )

$mech->setRequestInterception(
    { urlPattern => '*', resourceType => 'Document', interceptionStage => 'Request'},
    { urlPattern => '*', resourceType => 'Media', interceptionStage => 'Response'},
);

Sets the list of request patterns and resource types for which the interception callback will be invoked.

$mech->on_request_intercepted( $cb )

$mech->on_request_intercepted( sub {
    my( $mech, $info ) = @_;
    warn $info->{request}->{url};
    $mech->continueInterceptedRequest_future(
        interceptionId => $info->{interceptionId}
    )
});

A callback for intercepted requests that match the patterns set up via setRequestInterception.

If you return a future from this callback, it will not be discarded but kept in a safe place.

$mech->searchInResponseBody( $id, %options )

my $request_id = ...;
my @matches = $mech->searchInResponseBody(
    requestId     => $request_id,
    query         => 'rumpelstiltskin',
    caseSensitive => JSON::PP::true,
    isRegex       => JSON::PP::false,
);
for( @matches ) {
    print $_->{lineNumber}, ":", $_->{lineContent}, "\n";
};

Returns the matches (if any) for a string or regular expression within a response.

$mech->on_dialog( $cb )

$mech->on_dialog( sub {
    my( $mech, $dialog ) = @_;
    warn $dialog->{message};
    $mech->handle_dialog( 1 ); # click "OK" / "yes" instead of "cancel"
});

A callback for Javascript dialogs (alert(), prompt(), ... )

$mech->handle_dialog( $accept, $prompt = undef )

$mech->on_dialog( sub {
    my( $mech, $dialog ) = @_;
    warn "[Javascript $dialog->{type}]: $dialog->{message}";
    $mech->handle_dialog( 1 ); # click "OK" / "yes" instead of "cancel"
});

Closes the current Javascript dialog. Depending on

$mech->js_console_entries()

print $_->{type}, " ", $_->{message}, "\n"
    for $mech->js_console_entries();

An interface to the Javascript Error Console

Returns the list of entries in the JEC

$mech->js_errors()

print "JS error: ", $_->{message}, "\n"
    for $mech->js_errors();

Returns the list of errors in the JEC

$mech->clear_js_errors()

$mech->clear_js_errors();

Clears all Javascript messages from the console

$mech->eval_in_page( $str, @args )

$mech->eval( $str, @args )

my ($value, $type) = $mech->eval( '2+2' );

Evaluates the given Javascript fragment in the context of the web page. Returns a pair of value and Javascript type.

This allows access to variables and functions declared "globally" on the web page.

This method is special to WWW::Mechanize::Chrome.

$mech->eval_in_chrome $code, @args

$mech->eval_in_chrome(<<'JS', "Foobar/1.0");
    this.settings.userAgent= arguments[0]
JS

Evaluates Javascript code in the context of Chrome.

This allows you to modify properties of Chrome.

This is currently not implemented.

$mech->highlight_node( @nodes )

my @links = $mech->selector('a');
$mech->highlight_node(@links);
print $mech->content_as_png();

Convenience method that marks all nodes in the arguments with a red frame.

This is convenient if you need visual verification that you've got the right nodes.

NAVIGATION METHODS

$mech->get( $url, %options )

my $response = $mech->get( $url );

Retrieves the URL URL.

It returns a HTTP::Response object for interface compatibility with WWW::Mechanize.

Note that Chrome does not support download of files.

$mech->_collectEvents

my $events = $mech->_collectEvents(
    sub { $_[0]->{method} eq 'Page.loadEventFired' }
);
my( $e,$r) = Future->wait_all( $events, $self->driver->send_message(...));

Internal method to create a Future that waits for an event that is sent by Chrome.

The subroutine is the predicate to check to see if the current event is the event we have been waiting for.

The result is a Future that will return all captured events.

$mech->get_local( $filename , %options )

$mech->get_local('test.html');

Shorthand method to construct the appropriate file:// URI and load it into Chrome. Relative paths will be interpreted as relative to $0.

This method accepts the same options as ->get().

This method is special to WWW::Mechanize::Chrome but could also exist in WWW::Mechanize through a plugin.

Warning: Chrome does not handle local files well. Especially subframes do not get loaded properly.

$mech->getRequestPostData

if( $info->{params}->{response}->{requestHeaders}->{":method"} eq 'POST' ) {
    $req->{postBody} = $m->getRequestPostData( $id );
};

Retrieves the data sent with a POST request

$mech->post( $url, %options )

not implemented

$mech->post( 'http://example.com',
    params => { param => "Hello World" },
    headers => {
      "Content-Type" => 'application/x-www-form-urlencoded',
    },
    charset => 'utf-8',
);

Sends a POST request to $url.

A Content-Length header will be automatically calculated if it is not given.

The following options are recognized:

$mech->reload( %options )

$mech->reload( ignoreCache => 1 )

Acts like the reload button in a browser: repeats the current request. The history (as per the "back" method) is not altered.

Returns the HTTP::Response object from the reload, or undef if there's no current request.

$mech->set_download_directory( $dir )

my $downloads = tempdir();
$mech->set_download_directory( $downloads );

Enables automatic file downloads and sets the directory where the files will be downloaded to. Setting this to undef will disable downloads again.

The directory in $dir must be an absolute path, since Chrome does not know about the current directory of your Perl script.

$mech->add_header( $name => $value, ... )

$mech->add_header(
    'X-WWW-Mechanize-Chrome' => "I'm using it",
    Encoding => 'text/klingon',
);

This method sets up custom headers that will be sent with every HTTP(S) request that Chrome makes.

Note that currently, we only support one value per header.

$mech->delete_header( $name , $name2... )

$mech->delete_header( 'User-Agent' );

Removes HTTP headers from the agent's list of special headers. Note that Chrome may still send a header with its default value.

$mech->reset_headers

$mech->reset_headers();

Removes all custom headers and makes Chrome send its defaults again.

$mech->block_urls()

$mech->block_urls( '//facebook.com/js/conversions/tracking.js' );

Sets the list of blocked URLs. These URLs will not be retrieved by Chrome when loading a page. This is useful to eliminate tracking images or to test resilience in face of bad network conditions.

$mech->res() / $mech->response(%options)

my $response = $mech->response(headers => 0);

Returns the current response as a HTTP::Response object.

$mech->success()

$mech->get('http://google.com');
print "Yay"
    if $mech->success();

Returns a boolean telling whether the last request was successful. If there hasn't been an operation yet, returns false.

This is a convenience function that wraps $mech->res->is_success.

$mech->status()

$mech->get('http://google.com');
print $mech->status();
# 200

Returns the HTTP status code of the response. This is a 3-digit number like 200 for OK, 404 for not found, and so on.

$mech->back()

$mech->back();

Goes one page back in the page history.

Returns the (new) response.

$mech->forward()

$mech->forward();

Goes one page forward in the page history.

Returns the (new) response.

$mech->stop()

$mech->stop();

Stops all loading in Chrome, as if you pressed ESC.

This function is mostly of use in callbacks or in a timer callback from your event loop.

$mech->uri()

print "We are at " . $mech->uri;

Returns the current document URI.

CONTENT METHODS

$mech->document()

print $self->document->get->{nodeId};

Returns the document object as a Future.

This is WWW::Mechanize::Chrome specific.

$mech->content( %options )

print $mech->content;
print $mech->content( format => 'html' ); # default
print $mech->content( format => 'text' ); # identical to ->text

This always returns the content as a Unicode string. It tries to decode the raw content according to its input encoding. This currently only works for HTML pages, not for images etc.

Recognized options:

$mech->text()

print $mech->text();

Returns the text of the current HTML content. If the content isn't HTML, $mech will die.

$mech->content_encoding()

print "The content is encoded as ", $mech->content_encoding;

Returns the encoding that the content is in. This can be used to convert the content from UTF-8 back to its native encoding.

$mech->update_html( $html )

$mech->update_html($html);

Writes $html into the current document. This is mostly implemented as a convenience method for HTML::Display::MozRepl.

$mech->base()

print $mech->base;

Returns the URL base for the current page.

The base is either specified through a base tag or is the current URL.

This method is specific to WWW::Mechanize::Chrome.

$mech->content_type()

$mech->ct()

print $mech->content_type;

Returns the content type of the currently loaded document

$mech->is_html()

print $mech->is_html();

Returns true/false on whether our content is HTML, according to the HTTP headers.

$mech->title()

print "We are on page " . $mech->title;

Returns the current document title.

EXTRACTION METHODS

print $_->text . " -> " . $_->url . "\n"
    for $mech->links;

Returns all links in the document as WWW::Mechanize::Link objects.

Currently accepts no parameters. See ->xpath or ->selector when you want more control.

$mech->selector( $css_selector, %options )

my @text = $mech->selector('p.content');

Returns all nodes matching the given CSS selector. If $css_selector is an array reference, it returns all nodes matched by any of the CSS selectors in the array.

This takes the same options that ->xpath does.

This method is implemented via WWW::Mechanize::Plugin::Selector.

print $_->{innerHTML} . "\n"
    for $mech->find_link_dom( text_contains => 'CPAN' );

A method to find links, like WWW::Mechanize's ->find_links method. This method returns DOM objects from Chrome instead of WWW::Mechanize::Link objects.

Note that Chrome might have reordered the links or frame links in the document so the absolute numbers passed via n might not be the same between WWW::Mechanize and WWW::Mechanize::Chrome.

The supported options are:

$mech->find_link( %options )

print $_->text . "\n"
    for $mech->find_link( text_contains => 'CPAN' );

A method quite similar to WWW::Mechanize's method. The options are documented in ->find_link_dom.

Returns a WWW::Mechanize::Link object.

This defaults to not look through child frames.

$mech->find_all_links( %options )

print $_->text . "\n"
    for $mech->find_all_links( text_regex => qr/google/i );

Finds all links in the document. The options are documented in ->find_link_dom.

Returns them as list or an array reference, depending on context.

This defaults to not look through child frames.

print $_->{innerHTML} . "\n"
    for $mech->find_all_links_dom( text_regex => qr/google/i );

Finds all matching linky DOM nodes in the document. The options are documented in ->find_link_dom.

Returns them as list or an array reference, depending on context.

This defaults to not look through child frames.

$mech->follow_link( %options )

$mech->follow_link( xpath => '//a[text() = "Click here!"]' );

Follows the given link. Takes the same parameters that find_link_dom uses.

Note that ->follow_link will only try to follow link-like things like A tags.

$mech->xpath( $query, %options )

my $link = $mech->xpath('//a[id="clickme"]', one => 1);
# croaks if there is no link or more than one link found

my @para = $mech->xpath('//p');
# Collects all paragraphs

my @para_text = $mech->xpath('//p/text()', type => $mech->xpathResult('STRING_TYPE'));
# Collects all paragraphs as text

Runs an XPath query in Chrome against the current document.

If you need more information about the returned results, use the ->xpathEx() function.

The options allow the following keys:

Returns the matched results as WWW::Mechanize::Chrome::Node objects.

You can pass in a list of queries as an array reference for the first parameter. The result will then be the list of all elements matching any of the queries.

This is a method that is not implemented in WWW::Mechanize.

In the long run, this should go into a general plugin for WWW::Mechanize.

$mech->by_id( $id, %options )

my @text = $mech->by_id('_foo:bar');

Returns all nodes matching the given ids. If $id is an array reference, it returns all nodes matched by any of the ids in the array.

This method is equivalent to calling ->xpath :

$self->xpath(qq{//*[\@id="$_"]}, %options)

It is convenient when your element ids get mistaken for CSS selectors.

$mech->click( $name [,$x ,$y] )

$mech->click( 'go' );
$mech->click({ xpath => '//button[@name="go"]' });

Has the effect of clicking a button (or other element) on the current form. The first argument is the name of the button to be clicked. The second and third arguments (optional) allow you to specify the (x,y) coordinates of the click.

If there is only one button on the form, $mech->click() with no arguments simply clicks that one button.

If you pass in a hash reference instead of a name, the following keys are recognized:

Returns a HTTP::Response object.

As a deviation from the WWW::Mechanize API, you can also pass a hash reference as the first parameter. In it, you can specify the parameters to search much like for the find_link calls.

$mech->click_button( ... )

$mech->click_button( name => 'go' );
$mech->click_button( input => $mybutton );

Has the effect of clicking a button on the current form by specifying its name, value, or index. Its arguments are a list of key/value pairs. Only one of name, number, input or value must be specified in the keys.

If you find yourself wanting to specify a button through its selector or xpath, consider using ->click instead.

FORM METHODS

$mech->current_form()

print $mech->current_form->{name};

Returns the current form.

This method is incompatible with WWW::Mechanize. It returns the DOM <form> object and not a HTML::Form instance.

The current form will be reset by WWW::Mechanize::Chrome on calls to ->get() and ->get_local(), and on calls to ->submit() and ->submit_with_fields.

$mech->dump_forms( [$fh] )

open my $fh, '>', 'form-log.txt'
    or die "Couldn't open logfile 'form-log.txt': $!";
$mech->dump_forms( $fh );

Prints a dump of the forms on the current page to the filehandle $fh. If $fh is not specified or is undef, it dumps to STDOUT.

$mech->form_name( $name [, %options] )

$mech->form_name( 'search' );

Selects the current form by its name. The options are identical to those accepted by the "$mech->xpath" method.

$mech->form_id( $id [, %options] )

$mech->form_id( 'login' );

Selects the current form by its id attribute. The options are identical to those accepted by the "$mech->xpath" method.

This is equivalent to calling

$mech->by_id($id,single => 1,%options)

$mech->form_number( $number [, %options] )

$mech->form_number( 2 );

Selects the numberth form. The options are identical to those accepted by the "$mech->xpath" method.

$mech->form_with_fields( [$options], @fields )

$mech->form_with_fields(
    'user', 'password'
);

Find the form which has the listed fields.

If the first argument is a hash reference, it's taken as options to ->xpath.

See also "$mech->submit_form".

$mech->forms( %options )

my @forms = $mech->forms();

When called in a list context, returns a list of the forms found in the last fetched page. In a scalar context, returns a reference to an array with those forms.

The options are identical to those accepted by the "$mech->selector" method.

The returned elements are the DOM <form> elements.

$mech->field( $selector, $value, [,\@pre_events [,\@post_events]] )

$mech->field( user => 'joe' );
$mech->field( not_empty => '', [], [] ); # bypass JS validation

Sets the field with the name given in $selector to the given value. Returns the value.

The method understands very basic CSS selectors in the value for $selector, like the HTML::Form find_input() method.

A selector prefixed with '#' must match the id attribute of the input. A selector prefixed with '.' matches the class attribute. A selector prefixed with '^' or with no prefix matches the name attribute.

By passing the array reference @pre_events, you can indicate which Javascript events you want to be triggered before setting the value. @post_events contains the events you want to be triggered after setting the value.

By default, the events set in the constructor for pre_events and post_events are triggered.

$mech->upload( $selector, $value )

$mech->upload( user_picture => 'C:/Users/Joe/face.png' );

Sets the file upload field with the name given in $selector to the given file. The filename must be an absolute path and filename in the local filesystem.

The method understands very basic CSS selectors in the value for $selector, like the ->field method.

$mech->value( $selector_or_element, [%options] )

print $mech->value( 'user' );

Returns the value of the field given by $selector_or_name or of the DOM element passed in.

The legacy form of

$mech->value( name => value );

is also still supported but will likely be deprecated in favour of the ->field method.

For fields that can have multiple values, like a select field, the method is context sensitive and returns the first selected value in scalar context and all values in list context.

Note that this method does not support file uploads. See the ->upload method for that.

$mech->get_set_value( %options )

Allows fine-grained access to getting/setting a value with a different API. Supported keys are:

name
value
pre
post

in addition to all keys that $mech->xpath supports.

$mech->submit( $form )

$mech->submit;

Submits the form. Note that this does not fire the onClick event and thus also does not fire eventual Javascript handlers. Maybe you want to use $mech->click instead.

The default is to submit the current form as returned by $mech->current_form.

$mech->submit_form( %options )

$mech->submit_form(
    with_fields => {
        user => 'me',
        pass => 'secret',
    }
);

This method lets you select a form from the previously fetched page, fill in its fields, and submit it. It combines the form_number/form_name, set_fields and click methods into one higher level call. Its arguments are a list of key/value pairs, all of which are optional.

$mech->set_fields( $name => $value, ... )

$mech->set_fields(
    user => 'me',
    pass => 'secret',
);

This method sets multiple fields of the current form. It takes a list of field name and value pairs. If there is more than one field with the same name, the first one found is set. If you want to select which of the duplicate field to set, use a value which is an anonymous array which has the field value and its number as the 2 elements.

CONTENT RENDERING METHODS

$mech->content_as_png()

my $png_data = $mech->content_as_png();

# Create scaled-down 480px wide preview
my $png_data = $mech->content_as_png(undef, { width => 480 });

Returns the given tab or the current page rendered as PNG image.

All parameters are optional.

This method is specific to WWW::Mechanize::Chrome.

$mech->viewport_size

print Dumper $mech->viewport_size;
$mech->viewport_size({ width => 1388, height => 792 });

Returns (or sets) the new size of the viewport (the "window").

The recognized keys are:

width
height
deviceScaleFactor
mobile
screenWidth
screenHeight
positionX
positionY

$mech->element_as_png( $element )

my $shiny = $mech->selector('#shiny', single => 1);
my $i_want_this = $mech->element_as_png($shiny);

Returns PNG image data for a single element

$mech->render_element( %options )

my $shiny = $mech->selector('#shiny', single => 1);
my $i_want_this= $mech->render_element(
    element => $shiny,
    format => 'png',
);

Returns the data for a single element or writes it to a file. It accepts all options of ->render_content.

Note that while the image will have the node in the upper left corner, the width and height of the resulting image will still be the size of the browser window. Cut the image using element_coordinates if you need exactly the element.

$mech->element_coordinates( $element )

my $shiny = $mech->selector('#shiny', single => 1);
my ($pos) = $mech->element_coordinates($shiny);
print $pos->{left},',', $pos->{top};

Returns the page-coordinates of the $element in pixels as a hash with four entries, left, top, width and height.

This function might get moved into another module more geared towards rendering HTML.

$mech->render_content(%options)

my $pdf_data = $mech->render_content( format => 'pdf' );

Returns the current page rendered as PDF or PNG as a bytestring.

Note that the PDF format will only be successful with headless Chrome. At least on Windows, when launching Chrome with a UI, printing to PDF will be unavailable.

This method is specific to WWW::Mechanize::Chrome.

$mech->content_as_pdf(%options)

my $pdf_data = $mech->content_as_pdf();

Returns the current page rendered in PDF format as a bytestring.

Note that this method will only be successful with headless Chrome. At least on Windows, when launching Chrome with a UI, printing to PDF will be unavailable.

This method is specific to WWW::Mechanize::Chrome.

INTERNAL METHODS

These are methods that are available but exist mostly as internal helper methods. Use of these is discouraged.

$mech->element_query( \@elements, \%attributes )

my $query = $mech->element_query(['input', 'select', 'textarea'],
                           { name => 'foo' });

Returns the XPath query that searches for all elements with tagNames in @elements having the attributes %attributes. The @elements will form an or condition, while the attributes will form an and condition.

DEBUGGING METHODS

This module can collect the screencasts that Chrome can produce. The screencasts are sent to your callback which either feeds them to ffmpeg to create a video out of them or dumps them to disk as sequential images.

sub saveFrame {
    my( $mech, $framePNG ) = @_;
    # just ignore this frame
}

$mech->setScreenFrameCallback( \&saveFrame );
... do stuff ...
$mech->setScreenFrameCallback( undef ); # stop recording

$mech->sleep

$mech->sleep( 2 ); # wait for things to settle down

Suspends the progress of the program while still handling messages from Chrome.

The main use of this method is to give Chrome enough time to send all its screencast frames and to catch up before shutting down the connection.

INCOMPATIBILITIES WITH WWW::Mechanize

As this module is in a very early stage of development, there are many incompatibilities. The main thing is that only the most needed WWW::Mechanize methods have been implemented by me so far.

Unsupported Methods

At least the following methods are unsupported:

Functions that will likely never be implemented

These functions are unlikely to be implemented because they make little sense in the context of Chrome.

INSTALLING

Install the chrome executable

Test it has been installed on your system:

On unixish systems, the executable is named chrome-browser. Check that Chrome starts:

chrome-browser --version

On Windows, the executable is named chrome.exe and doesn't output information to the console. Check that Chrome starts:

chrome

Chrome versions

Note that the Chrome version numbers do not denote availability of features. Features can still be added to Chrome v62 when Chrome v64 is already out.

RUNNING THE TEST SUITE

The normal test invocation is 'make test'.

If your executable has a different name than chrome-browser or chrome.exe or is not in your path, then set the environment variable CHROME_BIN to the absolute path.

If you have Chrome already running, it must have been started with the <--remote-debugging-port=9222> option to enable access to the developer API. You may want to set up a dedicated and version pinned version of Chrome for your automation.

The test suite is apt to disturb your display when a locally running chrome browser gets animated. On unixish systems you can avoid this kind of disturbance by (1) not running any chrome binary and (2) start a separate display with Xvfb and (3) set the DISPLAY variable accordingly. E.g.:

Xvfb :121 &
DISPLAY=:121 CHROME_BIN=/usr/bin/google-chrome-stable make test
