OpenSwoole\Coroutine\Http\Client->setData(...)

Description

Set the body of the HTTP request, in other words the data to be sent with the request.

• If the header Content-Type is set to urlencoded format, then the client will automatically parse the data through http_build_query
• Any data which is set is not preserved once a request is made
• If the request is additionally using addFile or addData and setData is a string and not an array, the string value will be ignored because of differing formats. When using addFile or addData the format is form-data which is not compatible with a string. However, if setData is using an array, that key-value array will be added to the request

Example

Using Execute Method

<?php
use OpenSwoole\Coroutine\HTTP\Client;

co::run(function()
{
    $client = new Client('127.0.0.1', 80);

    $client->set(['timeout' => 1]);

    $client->setHeaders([
        'Host' => "localhost",
        "User-Agent" => 'Chrome/49.0.2587.3',
        'Accept' => 'text/html,application/xhtml+xml,application/xml',
        'Accept-Encoding' => 'gzip',
    ]);

    $client->setMethod('POST');

    // Add data to the request
    $client->setData(['msg'=> 'Hello','from'=>'Swoole']);

    $status = $client->execute('/index.php');

    echo $status . "\n";

    var_dump($client->body);

    $client->close();
});

The execute() function just takes the path only, not the domain. This allows you set use setMethod() to select a HTTP request type like GET, POST, PUT etc. and then add data and execute the request when ready.

Using Post Method

<?php
use OpenSwoole\Coroutine\HTTP\Client;

co::run(function()
{
    $client = new Client('127.0.0.1', 80);

    $client->set(['timeout' => 1]);

    $client->setHeaders([
        'Host' => "localhost",
        "User-Agent" => 'Chrome/49.0.2587.3',
        'Accept' => 'text/html,application/xhtml+xml,application/xml',
        'Accept-Encoding' => 'gzip',
    ]);

    // No need to set the method, post() does it for us, we send the data as well here
    $client->post('/index.php', ['msg'=> 'Hello','from'=>'Swoole']);

    echo $client->getStatus() . "\n";

    var_dump($client->getBody());

    echo $client->body;

    $client->close();
});

No need to use setMethod() when using post() as it is done for you and forced to use POST. Using the post() method means you must add the path but not the domain and then data as the second parameter.
