HTML::HTML5::Parser::UA(3) User Contributed Perl Documentation HTML::HTML5::Parser::UA(3)

HTML::HTML5::Parser::UA - simple web user agent class

 use aliased 'HTML::HTML5::Parser::UA';
 
 my $response = UA->get($url);
 die unless $response->{success};
 
 print $response->{decoded_content};

This is a simple wrapper around HTTP::Tiny and LWP::UserAgent to smooth out the API differences between them. It only supports bog standard "get($url)" requests.

If LWP::UserAgent is already in memory, this module will use that.

If LWP::UserAgent is not in memory, then this module will use HTTP::Tiny (or direct filesystem access for "file://" URLs).

If LWP::UserAgent is not in memory, and you attempt to request a URL that HTTP::Tiny cannot handle (e.g. an "ftp://" URL), then this module will load LWP::UserAgent and die if it cannot be loaded (e.g. is not installed).

HTML::HTML5::Parser::UA is used by the "parse_file" method of HTML::HTML5::Parser.

"get($url, $ua)"
Gets the URL and returns a hashref similar to HTTP::Tiny's hashrefs, but with an additional "decoded_content" key, which contains the response body, decoded into a Perl character string (not a byte string).

If $ua is given (it's optional), then this user agent will be used to perform the actual request. Must be undef or an LWP::UserAgent object (or a subclass) or an HTTP::Tiny object (or a subclass).

$HTML::HTML5::Parser::NO_LWP
If true, avoids using LWP::UserAgent.

LWP::UserAgent is a good piece of software but it has a dependency on HTML::Parser. HTML::Parser is only used to provide one fairly esoteric feature, which this package doesn't make use of. (It's the "parse_head" option.)

Because of that, I don't especially want HTML::HTML5::Parser to have a dependency on LWP::UserAgent. Hence this module.

HTML::HTML5::Parser.
