DESCRIPTIONPOE::Filter::HTTP::Parser is a POE::Filter for HTTP which is based on HTTP::Parser.
It can be used to easily create POE based HTTP servers or clients.
With the "type" set to "client", which is the default behaviour, "get" will parse HTTP::Response objects from HTTP streams and "put" will accept HTTP::Request objects and convert them to HTTP streams.
With the "type" set to "server", the reverse will happen. "get" will parse HTTP::Request objects from HTTP streams and "put" will accept HTTP::Response objects and convert them to HTTP streams. Like POE::Filter::HTTPD if there is an error parsing the HTTP request, this filter will generate a HTTP::Response object instead, to encapsulate the error message, suitable for simply sending back to the requesting client.
Creates a new POE::Filter::HTTP::Parser object. Takes one optional argument, "type" which
determines whether the filter will act in "client" or "server" mode. "client" is the default
if "type" is not specified.
'type', set to either 'client' or 'server', default is 'client';
- Takes an arrayref which contains lines of text. Returns an arrayref of either HTTP::Request or HTTP::Response objects depending on the "type" that has been specified.
- Returns any data remaining in a filter's input buffer. The filter's input buffer is not cleared, however. Returns an array reference if there's any data, or undef if the filter was empty.
Takes an arrayref of either HTTP::Response objects or HTTP::Request objects depending on whether
"type" is set to "server" or "client", respectively.
If "type" is "client", then this accepts HTTP::Request objects. If "type" is "server", then this accepts HTTP::Response objects.
This does make sense if you think about it.
The given objects are returned to their stream form.
- Makes a copy of the filter, and clears the copy's buffer.
CREDITSThe "put" method for HTTP responses was borrowed from POE::Filter::HTTPD, along with the code to generate HTTP::Response on a parse error, by Artur Bergman and Rocco Caputo.
