HTTP::Status - HTTP Status code processing
use HTTP::Status; if ($rc != RC_OK) { print status_message($rc), "\n"; } if (is_success($rc)) { ... } if (is_error($rc)) { ... } if (is_redirect($rc)) { ... }
HTTP::Status is a library of routines for defining and classification of HTTP status codes for libwww-perl. Status codes are used to encode the overall outcome of a HTTP response message. Codes correspond to those defined in <draft-ietf-http-v11-spec-06>.
The following functions can be used as mnemonic status code names:
RC_CONTINUE (100) RC_SWITCHING_PROTOCOLS (101) RC_OK (200) RC_CREATED (201) RC_ACCEPTED (202) RC_NON_AUTHORITATIVE_INFORMATION (203) RC_NO_CONTENT (204) RC_RESET_CONTENT (205) RC_PARTIAL_CONTENT (206) RC_MULTIPLE_CHOICES (300) RC_MOVED_PERMANENTLY (301) RC_MOVED_TEMPORARILY (302) RC_SEE_OTHER (303) RC_NOT_MODIFIED (304) RC_USE_PROXY (305) RC_BAD_REQUEST (400) RC_UNAUTHORIZED (401) RC_PAYMENT_REQUIRED (402) RC_FORBIDDEN (403) RC_NOT_FOUND (404) RC_METHOD_NOT_ALLOWED (405) RC_NOT_ACCEPTABLE (406) RC_PROXY_AUTHENTICATION_REQUIRED (407) RC_REQUEST_TIMEOUT (408) RC_CONFLICT (409) RC_GONE (410) RC_LENGTH_REQUIRED (411) RC_PRECONDITION_FAILED (412) RC_REQUEST_ENTITY_TOO_LARGE (413) RC_REQUEST_URI_TOO_LARGE (414) RC_UNSUPPORTED_MEDIA_TYPE (415) RC_INTERNAL_SERVER_ERROR (500) RC_NOT_IMPLEMENTED (501) RC_BAD_GATEWAY (502) RC_SERVICE_UNAVAILABLE (503) RC_GATEWAY_TIMEOUT (504) RC_HTTP_VERSION_NOT_SUPPORTED (505)
The status_message() function will translate status codes to human readable strings.
The is_info(), is_success(), is_redirect(), and is_error() functions will return a TRUE value if the status code passed as argument is informational, indicates success, and error, or a redirect respectively.
