Mojo::Transaction::HTTP - HTTP transaction
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!');
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>.
Mojo::Transaction::HTTP inherits all events from Mojo::Transaction and can emit the following new ones.
$tx->on(request => sub ($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!') });
$tx->on(resume => sub ($tx) {...});
Emitted when transaction is resumed.
$tx->on(unexpected => sub ($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.' }) });
Mojo::Transaction::HTTP inherits all attributes from Mojo::Transaction and implements the following new ones.
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;
Mojo::Transaction::HTTP inherits all methods from Mojo::Transaction and implements the following new ones.
$tx->client_read($bytes);
Read data client-side, used to implement user agents such as Mojo::UserAgent.
my $bytes = $tx->client_write;
Write data client-side, used to implement user agents such as Mojo::UserAgent.
my $bool = $tx->is_empty;
Check transaction for "HEAD" request and "1xx", 204 or 304 response.
my $bool = $tx->keep_alive;
Check if connection can be kept alive.
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};
$tx = $tx->resume;
Resume transaction.
$tx->server_read($bytes);
Read data server-side, used to implement web servers such as Mojo::Server::Daemon.
my $bytes = $tx->server_write;
