=head1 NAME

HTTP::Request - HTTP style request message

=head1 VERSION

version 6.29

=head1 SYNOPSIS

require HTTP::Request;
 $request = HTTP::Request->new(GET => 'http://www.example.com/');

and usually used like this:

$ua = LWP::UserAgent->new;
 $response = $ua->request($request);

=head1 DESCRIPTION

C<HTTP::Request> is a class encapsulating HTTP style requests,
consisting of a request line, some headers, and a content body. Note
that the LWP library uses HTTP style requests even for non-HTTP
protocols.  Instances of this class are usually passed to the
request() method of an C<LWP::UserAgent> object.

C<HTTP::Request> is a subclass of C<HTTP::Message> and therefore
inherits its methods.  The following additional methods are available:

=over 4

=item $r = HTTP::Request->new( $method, $uri )

=item $r = HTTP::Request->new( $method, $uri, $header )

=item $r = HTTP::Request->new( $method, $uri, $header, $content )

Constructs a new C<HTTP::Request> object describing a request on the
object $uri using method $method.  The $method argument must be a
string.  The $uri argument can be either a string, or a reference to a
C<URI> object.  The optional $header argument should be a reference to
an C<HTTP::Headers> object or a plain array reference of key/value
pairs.  The optional $content argument should be a string of bytes.

=item $r = HTTP::Request->parse( $str )

This constructs a new request object by parsing the given string.

=item $r->method

=item $r->method( $val )

This is used to get/set the method attribute.  The method should be a
short string like "GET", "HEAD", "PUT", "PATCH" or "POST".

=item $r->uri

=item $r->uri( $val )

This is used to get/set the uri attribute.  The $val can be a
reference to a URI object or a plain string.  If a string is given,
then it should be parsable as an absolute URI.

=item $r->header( $field )

=item $r->header( $field => $value )

This is used to get/set header values and it is inherited from
C<HTTP::Headers> via C<HTTP::Message>.  See L<HTTP::Headers> for
details and other similar methods that can be used to access the
headers.

=item $r->accept_decodable

This will set the C<Accept-Encoding> header to the list of encodings
that decoded_content() can decode.

=item $r->content

=item $r->content( $bytes )

This is used to get/set the content and it is inherited from the
C<HTTP::Message> base class.  See L<HTTP::Message> for details and
other methods that can be used to access the content.

Note that the content should be a string of bytes.  Strings in perl
can contain characters outside the range of a byte.  The C<Encode>
module can be used to turn such strings into a string of bytes.

=item $r->as_string

=item $r->as_string( $eol )

Method returning a textual representation of the request.

=head1 EXAMPLES

Creating requests to be sent with L<LWP::UserAgent> or others can be easy. Here
are a few examples.

=head2 Simple POST

Here, we'll create a simple POST request that could be used to send JSON data
to an endpoint.

#!/usr/bin/env perl

use strict;
    use warnings;

use HTTP::Request ();
    use JSON::MaybeXS qw(encode_json);

my $url = 'https://www.example.com/api/user/123';
    my $header = ['Content-Type' => 'application/json; charset=UTF-8'];
    my $data = {foo => 'bar', baz => 'quux'};
    my $encoded_data = encode_json($data);

my $r = HTTP::Request->new('POST', $url, $header, $encoded_data);
    # at this point, we could send it via LWP::UserAgent
    # my $ua = LWP::UserAgent->new();
    # my $res = $ua->request($r);

=head2 Batch POST Request

Some services, like Google, allow multiple requests to be sent in one batch.
L<https://developers.google.com/drive/v3/web/batch> for example. Using the
C<add_part> method from L<HTTP::Message> makes this simple.

#!/usr/bin/env perl

use strict;
    use warnings;

use HTTP::Request ();
    use JSON::MaybeXS qw(encode_json);

my $auth_token = 'auth_token';
    my $batch_url = 'https://www.googleapis.com/batch';
    my $url = 'https://www.googleapis.com/drive/v3/files/fileId/permissions?fields=id';
    my $url_no_email = 'https://www.googleapis.com/drive/v3/files/fileId/permissions?fields=id&sendNotificationEmail=false';

# generate a JSON post request for one of the batch entries
    my $req1 = build_json_request($url, {
        emailAddress => 'example@appsrocks.com',
        role => "writer",
        type => "user",
    });

# generate a JSON post request for one of the batch entries
    my $req2 = build_json_request($url_no_email, {
        domain => "appsrocks.com",
        role => "reader",
        type => "domain",
    });

# generate a multipart request to send all of the other requests
    my $r = HTTP::Request->new('POST', $batch_url, [
        'Accept-Encoding' => 'gzip',
        # if we don't provide a boundary here, HTTP::Message will generate
        # one for us. We could use UUID::uuid() here if we wanted.
        'Content-Type' => 'multipart/mixed; boundary=END_OF_PART'
    ]);

# add the two POST requests to the main request
    $r->add_part($req1, $req2);
    # at this point, we could send it via LWP::UserAgent
    # my $ua = LWP::UserAgent->new();
    # my $res = $ua->request($r);
    exit();

sub build_json_request {
        my ($url, $href) = @_;
        my $header = ['Authorization' => "Bearer $auth_token", 'Content-Type' => 'application/json; charset=UTF-8'];
        return HTTP::Request->new('POST', $url, $header, encode_json($href));
    }
