NAME

Mojo::UserAgent::Transactor - User agent transactor  

SYNOPSIS

  use Mojo::UserAgent::Transactor;

  # GET request with Accept header
  my $t = Mojo::UserAgent::Transactor->new;
  say $t->tx(GET => 'http://example.com' => {Accept => '*/*'})->req->to_string;

  # POST request with form-data
  say $t->tx(POST => 'example.com' => form => {a => 'b'})->req->to_string;

  # PUT request with JSON data
  say $t->tx(PUT => 'example.com' => json => {a => 'b'})->req->to_string;

 

DESCRIPTION

Mojo::UserAgent::Transactor is the transaction building and manipulation framework used by Mojo::UserAgent.  

GENERATORS

These content generators are available by default.  

form

  $t->tx(POST => 'http://example.com' => form => {a => 'b'});

Generate query string, "application/x-www-form-urlencoded" or "multipart/form-data" content. See ``tx'' for more.  

json

  $t->tx(PATCH => 'http://example.com' => json => {a => 'b'});

Generate JSON content with Mojo::JSON. See ``tx'' for more.  

multipart

  $t->tx(PUT => 'http://example.com' => multipart => ['Hello', 'World!']);

Generate multipart content. See ``tx'' for more.  

ATTRIBUTES

Mojo::UserAgent::Transactor implements the following attributes.  

compressed

  my $bool = $t->compressed;
  $t       = $t->compressed($bool);

Try to negotiate compression for the response content and decompress it automatically, defaults to the value of the "MOJO_GZIP" environment variable or true.  

generators

  my $generators = $t->generators;
  $t             = $t->generators({foo => sub {...}});

Registered content generators, by default only "form", "json" and "multipart" are already defined.  

name

  my $name = $t->name;
  $t       = $t->name('Mojolicious');

Value for "User-Agent" request header of generated transactions, defaults to "Mojolicious (Perl)".  

METHODS

Mojo::UserAgent::Transactor inherits all methods from Mojo::Base and implements the following new ones.  

add_generator

  $t = $t->add_generator(foo => sub {...});

Register a content generator.

  $t->add_generator(foo => sub {
    my ($t, $tx, @args) = @_;
    ...
  });

 

endpoint

  my ($proto, $host, $port) = $t->endpoint(Mojo::Transaction::HTTP->new);

Actual endpoint for transaction.  

peer

  my ($proto, $host, $port) = $t->peer(Mojo::Transaction::HTTP->new);

Actual peer for transaction.  

promisify

  $t->promisify(Mojo::Promise->new, Mojo::Transaction::HTTP->new);

Resolve or reject Mojo::Promise object with Mojo::Transaction::HTTP object.  

proxy_connect

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

Build Mojo::Transaction::HTTP proxy "CONNECT" request for transaction if possible.  

redirect

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

Build Mojo::Transaction::HTTP follow-up request for 301, 302, 303, 307 or 308 redirect response if possible.  

tx

  my $tx = $t->tx(GET  => 'example.com');
  my $tx = $t->tx(POST => 'http://example.com');
  my $tx = $t->tx(GET  => 'http://example.com' => {Accept => '*/*'});
  my $tx = $t->tx(PUT  => 'http://example.com' => 'Content!');
  my $tx = $t->tx(PUT  => 'http://example.com' => form => {a => 'b'});
  my $tx = $t->tx(PUT  => 'http://example.com' => json => {a => 'b'});
  my $tx = $t->tx(PUT  => 'https://example.com' => multipart => ['a', 'b']);
  my $tx = $t->tx(POST => 'example.com' => {Accept => '*/*'} => 'Content!');
  my $tx = $t->tx(
    PUT => 'example.com' => {Accept => '*/*'} => form => {a => 'b'});
  my $tx = $t->tx(
    PUT => 'example.com' => {Accept => '*/*'} => json => {a => 'b'});
  my $tx = $t->tx(
    PUT => 'example.com' => {Accept => '*/*'} => multipart => ['a', 'b']);

Versatile general purpose Mojo::Transaction::HTTP transaction builder for requests, with support for ``GENERATORS''.

  # Generate and inspect custom GET request with DNT header and content
  say $t->tx(GET => 'example.com' => {DNT => 1} => 'Bye!')->req->to_string;

  # Stream response content to STDOUT
  my $tx = $t->tx(GET => 'http://example.com');
  $tx->res->content->unsubscribe('read')->on(read => sub { say $_[1] });

  # PUT request with content streamed from file
  my $tx = $t->tx(PUT => 'http://example.com');
  $tx->req->content->asset(Mojo::Asset::File->new(path => '/foo.txt'));

The "json" content generator uses Mojo::JSON for encoding and sets the content type to "application/json".

  # POST request with "application/json" content
  my $tx = $t->tx(
    POST => 'http://example.com' => json => {a => 'b', c => [1, 2, 3]});

The "form" content generator will automatically use query parameters for "GET" and "HEAD" requests.

  # GET request with query parameters
  my $tx = $t->tx(GET => 'http://example.com' => form => {a => 'b'});

For all other request methods the "application/x-www-form-urlencoded" content type is used.

  # POST request with "application/x-www-form-urlencoded" content
  my $tx = $t->tx(
    POST => 'http://example.com' => form => {a => 'b', c => 'd'});

Parameters may be encoded with the "charset" option.

  # PUT request with Shift_JIS encoded form values
  my $tx = $t->tx(
    PUT => 'example.com' => form => {a => 'b'} => charset => 'Shift_JIS');

An array reference can be used for multiple form values sharing the same name.

  # POST request with form values sharing the same name
  my $tx = $t->tx(
    POST => 'http://example.com' => form => {a => ['b', 'c', 'd']});

A hash reference with a "content" or "file" value can be used to switch to the "multipart/form-data" content type for file uploads.

  # POST request with "multipart/form-data" content
  my $tx = $t->tx(
    POST => 'http://example.com' => form => {mytext => {content => 'lala'}});

  # POST request with multiple files sharing the same name
  my $tx = $t->tx(POST => 'http://example.com' =>
    form => {mytext => [{content => 'first'}, {content => 'second'}]});

The "file" value should contain the path to the file you want to upload or an asset object, like Mojo::Asset::File or Mojo::Asset::Memory.

  # POST request with upload streamed from file
  my $tx = $t->tx(
    POST => 'http://example.com' => form => {mytext => {file => '/foo.txt'}});

  # POST request with upload streamed from asset
  my $asset = Mojo::Asset::Memory->new->add_chunk('lalala');
  my $tx    = $t->tx(
    POST => 'http://example.com' => form => {mytext => {file => $asset}});

A "filename" value will be generated automatically, but can also be set manually if necessary. All remaining values in the hash reference get merged into the "multipart/form-data" content as headers.

  # POST request with form values and customized upload (filename and header)
  my $tx = $t->tx(POST => 'http://example.com' => form => {
    a      => 'b',
    c      => 'd',
    mytext => {
      content        => 'lalala',
      filename       => 'foo.txt',
      'Content-Type' => 'text/plain'
    }
  });

The "multipart/form-data" content type can also be enforced by setting the "Content-Type" header manually.

  # Force "multipart/form-data"
  my $headers = {'Content-Type' => 'multipart/form-data'};
  my $tx = $t->tx(POST => 'example.com' => $headers => form => {a => 'b'});

The "multipart" content generator can be used to build custom multipart requests and does not set a content type.

  # POST request with multipart content ("foo" and "bar")
  my $tx = $t->tx(POST => 'http://example.com' => multipart => ['foo', 'bar']);

Similar to the "form" content generator you can also pass hash references with "content" or "file" values, as well as headers.

  # POST request with multipart content streamed from file
  my $tx = $t->tx(
    POST => 'http://example.com' => multipart => [{file => '/foo.txt'}]);

  # PUT request with multipart content streamed from asset
  my $headers = {'Content-Type' => 'multipart/custom'};
  my $asset   = Mojo::Asset::Memory->new->add_chunk('lalala');
  my $tx      = $t->tx(
    PUT => 'http://example.com' => $headers => multipart => [{file => $asset}]);

  # POST request with multipart content and custom headers
  my $tx = $t->tx(POST => 'http://example.com' => multipart => [
    {
      content            => 'Hello',
      'Content-Type'     => 'text/plain',
      'Content-Language' => 'en-US'
    },
    {
      content            => 'World!',
      'Content-Type'     => 'text/plain',
      'Content-Language' => 'en-US'
    }
  ]);

 

upgrade

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

Build Mojo::Transaction::WebSocket follow-up transaction for WebSocket handshake if possible.  

websocket

  my $tx = $t->websocket('ws://example.com');
  my $tx = $t->websocket('ws://example.com' => {DNT => 1} => ['v1.proto']);

Versatile Mojo::Transaction::HTTP transaction builder for WebSocket handshake requests.
