How to send files using Guzzle in PHP?

To send a file using Guzzle, you can utilize Guzzle’s multipart request method. Here is an example code demonstrating how to send a file with Guzzle:

require 'vendor/autoload.php'; //加载Guzzle库

use GuzzleHttp\Client;
use GuzzleHttp\Psr7\Request;
use GuzzleHttp\Psr7;

// 创建一个Guzzle客户端
$client = new Client();

// 要上传的文件
$file = '/path/to/file.jpg';

// 发送文件
$response = $client->request('POST', 'http://example.com/upload', [
    'multipart' => [
        [
            'name'     => 'file',
            'contents' => fopen($file, 'r'),
            'filename' => 'file.jpg'
        ]
    ],
]);

// 输出响应内容
echo $response->getBody();

In the example above, we start by creating a Guzzle client. Next, we specify the path of the file to upload and use the multipart option to add the file to the request. Finally, we send a POST request to http://example.com/upload and output the response content.

Please note that you may need to install the guzzlehttp/guzzle library, which can be done through Composer.

composer require guzzlehttp/guzzle

This way, you can use Guzzle to send files.
