VERSION

version 0.091710

use 5.010; use POE::Filter::SimpleHTTP; use POE::Filter::SimpleHTTP::Error; #exports constants by default

my $filter = POE::Filter::SimpleHTTP->new(); $filter->get_one_start([qw/junk data goes here/]); my $ret = $filter->get_one()->[0];

This module provides the error class and exported constants for use downstream from the filter to determine what went wrong.

error(): error() contains the actual error code from the filter that corresponds with the exported constants. Suitable for use in numeric comparisons (ie. ==)
context(): If the error has any context associated with it, it will be stored here. Note that some decompression routines do not provide a status message, just return undef, and so there is no context returned.

UNPARSABLE_PREAMBLE: The data provided doesn't parse for some reason as either a Response or Request. Context provided.
TRAILING_DATA: The message contains trailing data that isn't allowed by the RFC. Context provided.
CHUNKED_ISNT_LAST: chunked isn't last in the transfer encodings. This isn't allowed by the RFC. Context provided.
INFLATE_FAILED_INIT: Compress::Zlib::inflateInit failed. Context provided.
INFLATE_FAILED_INFLATE: inflate() failed. Context provided.
UNCOMPRESS_FAILED: uncompress() failed. No context.
GUNZIP_FAILED: memGunzip() failed. No context.
UNKNOWN_TRANSFER_ENCODING: A transfer encoding was not recognized. Context provided.
