DESCRIPTION

Parse HTTP/1.0 and HTTP/1.1 Messages.

METHODS

parse_headers( $string )

my @headers = HTTP::MessageParser->parse_headers($string);
my $headers = HTTP::MessageParser->parse_headers($string);

Parses Message Headers. field-name's are lowercased. Leading and trailing LWS is removed. LWS occurring between field-content are replaced with a single SP. Takes one argument, a string or a reference to a string, if it's a reference it will be consumed.

parse_request( $string )

my ( $Method, $Request_URI, $HTTP_Version, $Headers, $Body )
  = HTTP::MessageParser->parse_request($string);

Parses a Request. Expects a Request-Line followed by zero more header fields and an empty line. Content occurring after end of header fields is returned as a string reference, $Body. Takes one argument, a string or a reference to a string, if it's a reference it will be consumed.

Throws an exception upon failure.

parse_request_line( $string )

my ( $Method, $Request_URI, $HTTP_Version )
  = HTTP::MessageParser->parse_request_line($string);

Parses a Request-Line. Any leading CRLF is ignored. Takes one argument, a string or a reference to a string, if it's a reference it will be consumed.

Throws an exception upon failure.

parse_response( $string )

my ( $HTTP_Version, $Status_Code, $Reason_Phrase, $Headers, $Body )
  = HTTP::MessageParser->parse_response($string);

Parses a Response. Expects a Status-Line followed by zero more header fields and an empty line. Content occurring after end of header fields is returned as a string reference, $Body. Takes one argument, a string or a reference to a string, if it's a reference it will be consumed.

Throws an exception upon failure.

parse_response_line( $string )

my ( $HTTP_Version, $Status_Code, $Reason_Phrase )
  = HTTP::MessageParser->parse_response_line($string);

Parses a Status-Line. Takes one argument, a string or a reference to a string, if it's a reference it will be consumed.

Throws an exception upon failure.

parse_version( $string )

my ( $major, $minor ) = HTTP::MessageParser->parse_version($string);
my $version = HTTP::MessageParser->parse_version($string);

Parses a HTTP-Version string. In scalar context it returns a version number ( major * 1000 + minor ). In list context it returns major and minor as two separate integers.

Throws an exception upon failure.
