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 <https://tools.ietf.org/html/rfc7230> and RFC 7231 <https://tools.ietf.org/html/rfc7231>.
EVENTS¶
Mojo::Transaction::HTTP inherits all events from Mojo::Transaction and can emit the following new ones.
request¶
  $tx->on(request => sub ($tx) {...});
Emitted when a request is ready and needs to be handled.
  $tx->on(request => sub ($tx) { $tx->res->headers->header('X-Bender' => 'Bite my shiny metal ass!') });
resume¶
  $tx->on(resume => sub ($tx) {...});
Emitted when transaction is resumed.
unexpected¶
  $tx->on(unexpected => sub ($tx, $res) {...});
Emitted for unexpected "1xx" responses that will be ignored.
  $tx->on(unexpected => sub ($tx) { $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.
server_write¶
my $bytes = $tx->server_write;
Write data server-side, used to implement web servers such as Mojo::Server::Daemon.
