NAME

6       HTML::HTML5::Parser::UA - simple web user agent class
7

SYNOPSIS

9        use aliased 'HTML::HTML5::Parser::UA';
10
11        my $response = UA->get($url);
12        die unless $response->{success};
13
14        print $response->{decoded_content};
15

DESCRIPTION

17       This is a simple wrapper around HTTP::Tiny and LWP::UserAgent to smooth
18       out the API differences between them. It only supports bog standard
19       "get($url)" requests.
20
21       If LWP::UserAgent is already in memory, this module will use that.
22
23       If LWP::UserAgent is not in memory, then this module will use
24       HTTP::Tiny (or direct filesystem access for "file://" URLs).
25
26       If LWP::UserAgent is not in memory, and you attempt to request a URL
27       that HTTP::Tiny cannot handle (e.g. an "ftp://" URL), then this module
28       will load LWP::UserAgent and die if it cannot be loaded (e.g. is not
29       installed).
30
31       HTML::HTML5::Parser::UA is used by the "parse_file" method of
32       HTML::HTML5::Parser.
33
34   Class Method
35       "get($url, $ua)"
36           Gets the URL and returns a hashref similar to HTTP::Tiny's
37           hashrefs, but with an additional "decoded_content" key, which
38           contains the response body, decoded into a Perl character string
39           (not a byte string).
40
41           If $ua is given (it's optional), then this user agent will be used
42           to perform the actual request. Must be undef or an LWP::UserAgent
43           object (or a subclass) or an HTTP::Tiny object (or a subclass).
44
45   Package Variable
46       $HTML::HTML5::Parser::NO_LWP
47           If true, avoids using LWP::UserAgent.

MOTIVATION

50       LWP::UserAgent is a good piece of software but it has a dependency on
51       HTML::Parser. HTML::Parser is only used to provide one fairly esoteric
52       feature, which this package doesn't make use of. (It's the "parse_head"
53       option.)
54
55       Because of that, I don't especially want HTML::HTML5::Parser to have a
56       dependency on LWP::UserAgent. Hence this module.
