DESCRIPTION

This module handles the exchange of SOAP messages over HTTP with Any::Daemon as daemon implementation. It is a simple pre-forked daemon, much easier than the Net::Server implementations.

We use HTTP::Daemon as HTTP-connection implementation. The HTTP::Request and HTTP::Response objects (provided by HTTP-Message) are handled via functions provided by XML::Compile::SOAP::Daemon::LWPutil.

This abstraction level of the object (code in this pm file) is not concerned with parsing or composing XML, but only worries about the HTTP transport specifics of SOAP messages. The processing of the SOAP message is handled by the XML::Compile::SOAP::Daemon base-class.

The server is as flexible as possible: accept M-POST (HTTP Extension Framework) and POST (standard HTTP) for any message. It can be used for any SOAP1.1 and SOAP1.2 mixture. Although SOAP1.2 itself is not implemented yet.

METHODS

Constructors

XML::Compile::SOAP::Daemon::AnyDaemon->new(OPTIONS)

Create the server handler, which extends some class which implements a Net::Server daemon.

As OPTIONS, you can pass everything accepted by Any::Daemon subroutine new, like pid_file, user, group, and workdir,

 -Option            --Defined in     --Default
  accept_slow_select  XML::Compile::SOAP::Daemon  <true>
  output_charset      XML::Compile::SOAP::Daemon  'UTF-8'
  soap_action_input   XML::Compile::SOAP::Daemon  {}
  wsa_action_input    XML::Compile::SOAP::Daemon  {}
  wsa_action_output   XML::Compile::SOAP::Daemon  {}
accept_slow_select => BOOLEAN
output_charset => STRING
soap_action_input => HASH|ARRAY
wsa_action_input => HASH|ARRAY
wsa_action_output => HASH|ARRAY

Attributes

$obj->addSoapAction(HASH|PAIRS)

See "Attributes" in XML::Compile::SOAP::Daemon

$obj->addWsaTable(('INPUT'|'OUTPUT'), [HASH|PAIRS])

See "Attributes" in XML::Compile::SOAP::Daemon

$obj->outputCharset()

See "Attributes" in XML::Compile::SOAP::Daemon

Running the server

$obj->process(CLIENT, XMLIN, REQUEST, ACTION)

See "Running the server" in XML::Compile::SOAP::Daemon

$obj->run(OPTIONS)
 -Option         --Default
  background       <true>
  child_init       undef
  client_maxreq    100
  client_reqbonus  0
  client_timeout   30
  host             undef
  listen           SOMAXCONN
  max_childs       10
  port             undef
  postprocess      undef
  server_name      undef
  socket           undef
background => BOOLEAN
child_init => CODE

This CODE reference will get called by each child which gets started, before the "accept" waiting starts. Ideal moment to start your database-connection.

client_maxreq => NUMBER

Maximum number of requests per connection.

client_reqbonus => SECONDS

Time to add to the timeout as bonus per handled client request. Fast clients get more time over slow clients, more time to reach their maximum number of requests.

client_timeout => SECONDS

The maximum time a connection may exist, before being terminated.

host => STRING

Ignored when a socket is provided, otherwise required.

listen => INTEGER

Ignored when a socket is provided.

max_childs => INTEGER
port => INTEGER

Ignored when a socket is provided, otherwise required.

postprocess => CODE

See the section about this option in the DETAILS chapter of the XML::Compile::SOAP::Daemon::LWPutil manual-page.

server_name => STRING
socket => SOCKET

Pass your own socket, in stead of having one created for you. The SOCKET must be an IO::Socket::INET (or compatible like IO::Socket::SSL and IO::Socket::IP)

AnyDaemon with SSL

First, create certificates and let them be signed by a CA (or yourself) See http://devsec.org/info/ssl-cert.html to understand this.

  # generate secret private key
  openssl genrsa -out privkey.pem 1024

  # create a "certification request" (CSR)
  openssl req -new -key privkey.pem -out certreq.csr

  # send the CSR to the Certification Authority or self-sign:
  openssl x509 -req -days 3650 -in certreq.csr -signkey privkey.pem -out newcert.pem

  # publish server certificate
  ( openssl x509 -in newcert.pem; cat privkey.pem ) > server.pem
  ln -s server.pem `openssl x509 -hash -noout -in server.pem`.0   # dot-zero

Assuming that the certificates are in 'certs/', the program looks like this:

  use Log::Report;
  use XML::Compile::SOAP::Daemon::AnyDaemon;
  use XML::Compile::WSDL11;
  use IO::Socket::SSL       'SSL_VERIFY_NONE';
  use IO::Socket            'SOMAXCONN';

  my $daemon = XML::Compile::SOAP::Daemon::AnyDaemon->new;
  my $wsdl   = XML::Compile::WSDL11->new($wsdl);

  my %handlers = ();
  $daemon->operationsFromWSDL($wsdl, callbacks => \%handlers);

  my $socket = IO::Socket::SSL->new
   ( LocalHost  => 'localhost'
   , LocalPort  => 4444
   , Listen     => SOMAXCONN
   , Reuse      => 1
   , SSL_server => 1
   , SSL_verify_mode => SSL_VERIFY_NONE
   , SSL_key_file    => 'certs/privkey.pem'
   , SSL_cert_file   => 'certs/server.pem'
   ) or error __x"cannot create socket at {interface}: {err}"
         , interface => "$host:$port"
         , err => IO::Socket::SSL::errstr();

  $daemon->run
   ( name       => basename($0)
   , max_childs => 1
   , socket     => $socket
   , child_init => \&for_instance_connect_to_db
   )
