=head1 NAME

WWW::OAuth::Request::Basic - HTTP Request container for HTTP::Tiny

=head1 SYNOPSIS

 my $req = WWW::OAuth::Request::Basic->new(method => 'POST', url => $url, content => $content);
 $req->request_with(HTTP::Tiny->new);

=head1 DESCRIPTION

L is a request container for L that
stores the request parameters directly, for use with user-agents that do not
use request objects like L. It performs the role
L.

=head1 ATTRIBUTES

L implements the following attributes.

=head2 content

 my $content = $req->content;
 $req        = $req->content('foo=1&bar=2');

Request content string.

=head2 headers

 my $headers = $req->headers;
 $req        = $req->headers({});

Hashref of request headers. Must be updated carefully as headers are
case-insensitive. Values can be array references to specify multi-value
headers.

=head2 method

 my $method = $req->method;
 $req       = $req->method('GET');

Request method.

=head2 url

 my $url = $req->url;
 $req    = $req->url('http://example.com/api/');

Request URL.

=head1 METHODS

L composes all methods from L,
and implements the following new ones.

=head2 content_is_form

 my $bool = $req->content_is_form;

Check whether L contains a C header set to
C.

=head2 header

 my $header = $req->header('Content-Type');
 $req       = $req->header(Authorization => 'Basic foobar');

Set or return a request header in L.

=head2 set_form

 $req = $req->set_form({foo => 'bar'});

Convenience method to set L to a urlencoded form. Equivalent to:

 use WWW::OAuth::Util 'form_urlencode';
 $req->header('Content-Type' => 'application/x-www-form-urlencoded');
 $req->content(form_urlencode $form);

=head2 request_with

 my $res = $req->request_with(HTTP::Tiny->new);

Run request with passed L user-agent object, and return response
hashref, as in L.
