Name
SPVM::Mojo::UserAgent::Transactor - User agent transactor
Description
Mojo::UserAgent::Transactor class in SPVM is the transaction building and manipulation framework used by Mojo::UserAgent.
Usage
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" => [(object)form => {a => "b"}])->req->to_string;
# PUT request with JSON data
say $t->tx(PUT => "example.com" => [(object)json => {a => "b"}])->req->to_string;
Generators
These content generators are available by default.
form
$t->tx(POST => "http://example.com" => [(object)form => {a => "b"}]);
Generate query string, application/x-www-form-urlencoded
or multipart/form-data
content. See "tx" for more.

tx
method tx : Mojo::Transaction::HTTP ($method : string, $url : object of string|Mojo::URL, $args1 : object = undef, $args2 : object = undef);
Versatile general purpose Mojo::Transaction::HTTP transaction builder for requests, with support for "Generators".
Examples:
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" => [(object)form => {a => "b"}]);
my $tx = $t->tx(PUT => "http://example.com" => [(object)json => {a => "b"}]);
my $tx = $t->tx(PUT => "https://example.com" => [(object)multipart => ["a", "b"]]);
my $tx = $t->tx(POST => "example.com" => {Accept => "*/*"} => "Content!");
my $tx = $t->tx(PUT => "example.com" => {Accept => "*/*"} => [(object)form => {a => "b"}]);
my $tx = $t->tx(PUT => "example.com" => {Accept => "*/*"} => [(object)json => {a => "b"}]);
my $tx = $t->tx(PUT => "example.com" => {Accept => "*/*"} => [(object)multipart => ["a", "b"]]);
# 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");
(my $_ = $tx->res->content, $_->unsubscribe("read"), $_->on(read => method : void ($chunk : string) { say $string }));
# PUT request with content streamed from file
my $tx = $t->tx(PUT => "http://example.com");
$tx->req->content->asset((my $_ = Mojo::Asset::File->new, $_->set_path("/foo.txt"), $_));
The json
content generator uses 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" => [(object)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" => [(object)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" => [(object)form => {a => "b", c => "d"}]);
Parameters may be encoded with the foo
option.
# PUT request with Shift_JIS encoded form values
my $tx = $t->tx(PUT => "example.com" => [(object)form => {a => "b"} => {foo => "value"}]);
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" => [(object)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" => [(object)form => {mytext => {content => "lala"}]});
# POST request with multiple files sharing the same name
my $tx = $t->tx(POST => "http://example.com" => [(object)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" => [(object)form => {mytext => {file => "/foo.txt"}]});
# POST request with upload streamed from asset
my $asset = (my $_ = Mojo::Asset::Memory->new, $_->add_chunk("lalala"), $_);
my $tx = $t->tx(POST => "http://example.com" => [(object)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" => [(object)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 => [(object)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" => [(object)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" => [(object)multipart => [{file => "/foo.txt"}]]);
# PUT request with multipart content streamed from asset
my $headers = {"Content-Type" => "multipart/custom"};
my $asset = (my $_ = Mojo::Asset::Memory->new, $_->add_chunk("lalala"), $_);
my $tx = $t->tx(PUT => "http://example.com" => $headers => [(object)multipart => [{file => $asset}]]);
# POST request with multipart content and custom headers
my $tx = $t->tx(POST => "http://example.com" => [(object)multipart => [
{
content => "Hello",
"Content-Type" => "text/plain",
"Content-Language" => "en-US"
},
{
content => "World!",
"Content-Type" => "text/plain",
"Content-Language" => "en-US"
}
]]);
upgrade
method upgrade : Mojo::Transaction::WebSocket ($tx : Mojo::Transaction::HTTP);
Build Mojo::Transaction::WebSocket follow-up transaction for WebSocket handshake if possible.
