NAME

Mojo::Transaction::HTTP - HTTP transaction  

SYNOPSIS

  use Mojo::Transaction::HTTP;

  # Client
  my $tx = Mojo::Transaction::HTTP->new;
  $tx->req->method('GET');
  $tx->req->url->parse('http://example.com');
  $tx->req->headers->accept('application/json');
  say $tx->res->code;
  say $tx->res->headers->content_type;
  say $tx->res->body;
  say $tx->remote_address;

  # Server
  my $tx = Mojo::Transaction::HTTP->new;
  say $tx->req->method;
  say $tx->req->url->to_abs;
  say $tx->req->headers->accept;
  say $tx->remote_address;
  $tx->res->code(200);
  $tx->res->headers->content_type('text/plain');
  $tx->res->body('Hello World!');

 

DESCRIPTION

Mojo::Transaction::HTTP is a container for HTTP transactions, based on RFC 7230 <http://tools.ietf.org/html/rfc7230> and RFC 7231 <http://tools.ietf.org/html/rfc7231>.  

EVENTS

Mojo::Transaction::HTTP inherits all events from Mojo::Transaction and can emit the following new ones.  

request

  $tx->on(request => sub {
    my $tx = shift;
    ...
  });

Emitted when a request is ready and needs to be handled.

  $tx->on(request => sub {
    my $tx = shift;
    $tx->res->headers->header('X-Bender' => 'Bite my shiny metal ass!');
  });

 

resume

  $tx->on(resume => sub {
    my $tx = shift;
    ...
  });

Emitted when transaction is resumed.  

unexpected

  $tx->on(unexpected => sub {
    my ($tx, $res) = @_;
    ...
  });

Emitted for unexpected "1xx" responses that will be ignored.

  $tx->on(unexpected => sub {
    my $tx = shift;
    $tx->res->on(finish => sub { say 'Follow-up response is finished.' });
  });

 

ATTRIBUTES

Mojo::Transaction::HTTP inherits all attributes from Mojo::Transaction and implements the following new ones.  

previous

  my $previous = $tx->previous;
  $tx          = $tx->previous(Mojo::Transaction::HTTP->new);

Previous transaction that triggered this follow-up transaction, usually a Mojo::Transaction::HTTP object.

  # Paths of previous requests
  say $tx->previous->previous->req->url->path;
  say $tx->previous->req->url->path;

 

METHODS

Mojo::Transaction::HTTP inherits all methods from Mojo::Transaction and implements the following new ones.  

client_read

  $tx->client_read($bytes);

Read data client-side, used to implement user agents such as Mojo::UserAgent.  

client_write

  my $bytes = $tx->client_write;

Write data client-side, used to implement user agents such as Mojo::UserAgent.  

is_empty

  my $bool = $tx->is_empty;

Check transaction for "HEAD" request and "1xx", 204 or 304 response.  

keep_alive

  my $bool = $tx->keep_alive;

Check if connection can be kept alive.  

redirects

  my $redirects = $tx->redirects;

Return an array reference with all previous transactions that preceded this follow-up transaction.

  # Paths of all previous requests
  say $_->req->url->path for @{$tx->redirects};

 

resume

  $tx = $tx->resume;

Resume transaction.  

server_read

  $tx->server_read($bytes);

Read data server-side, used to implement web servers such as Mojo::Server::Daemon.
