Uploading Data

Guzzle provides several methods for uploading data.

You can send requests that contain a stream of data by passing a string, resource returned from fopen, or an instance of a Psr\Http\Message\StreamInterface to the body request option.

// Provide the body as a string.
$r = $client->request('POST', 'http://httpbin.org/post', [
    'body' => 'raw data'
]);
// Provide an fopen resource.
$body = fopen('/path/to/file', 'r');
$r = $client->request('POST', 'http://httpbin.org/post', ['body' => $body]);
// Use the stream_for() function to create a PSR-7 stream.
$body = \GuzzleHttp\Psr7\stream_for('hello!');
$r = $client->request('POST', 'http://httpbin.org/post', ['body' => $body]);

An easy way to upload JSON data and set the appropriate header is using the json request option:

$r = $client->request('PUT', 'http://httpbin.org/put', [
    'json' => ['foo' => 'bar']
]);

POST/Form Requests

In addition to specifying the raw data of a request using the body request option, Guzzle provides helpful abstractions over sending POST data.

Sending form fields

Sending application/x-www-form-urlencoded POST requests requires that you specify the POST fields as an array in the form_params request options.

$response = $client->request('POST', 'http://httpbin.org/post', [
    'form_params' => [
        'field_name' => 'abc',
        'other_field' => '123',
        'nested_field' => [
            'nested' => 'hello'
        ]
    ]
]);

Sending form files

You can send files along with a form (multipart/form-data POST requests), using the multipart request option. multipart accepts an array of associative arrays, where each associative array contains the following keys:

• name: (required, string) key mapping to the form field name.
• contents: (required, mixed) Provide a string to send the contents of the file as a string, provide an fopen resource to stream the contents from a PHP stream, or provide a Psr\Http\Message\StreamInterface to stream the contents from a PSR-7 stream.

$response = $client->request('POST', 'http://httpbin.org/post', [
    'multipart' => [
        [
            'name'     => 'field_name',
            'contents' => 'abc'
        ],
        [
            'name'     => 'file_name',
            'contents' => fopen('/path/to/file', 'r')
        ],
        [
            'name'     => 'other_file',
            'contents' => 'hello',
            'filename' => 'filename.txt',
            'headers'  => [
                'X-Foo' => 'this is an extra header to include'
            ]
        ]
    ]
]);
