如何在PHP中调用HTTP多部分/相关请求？

从this site，有一个我想要调用的HTTP请求。（不完全相同的凭据和内容，但结构相同）它用于发送彩信。如何在PHP中调用HTTP多部分/相关请求？

要发送请求，我在PHP中使用curl函数，但如果需要，我打开使用其他库。

问题是我在调用中看到多个Content-Type，据我所知，我不能在curl_setopt多次设置Content-Type？但是，它似乎不是多个HTTP请求，因为Host只出现一次。我如何在PHP中创建这样的HTTP请求？

最简单的将使用狂饮库：

https://guzzle.readthedocs.io/en/latest/request-options.html#multipart

$client = new \GuzzleHttp\Client([ 
    // Base URI is used with relative requests 
    'base_uri' => 'http://europe.ipx.com', 
    // You can set any number of default request options. 
    'timeout' => 2.0, 
]); 

$options = [ 
    'multipart' => [ 
     [ 
      'name'  => 'foo', 
      'contents' => 'data', 
      'headers' => ['Content-Type' => 'text/xml'] 
     ], 
     [ 
      'name'  => 'baz', 
      'contents' => fopen('/path/to/file', 'r'), 
      'headers' => ['Content-Type' => 'image/jpeg'] 
     ], 
     [ 
      'name'  => 'qux', 
      'contents' => fopen('/path/to/file', 'r'), 
      'filename' => 'custom_filename.txt', 
      'headers' => ['Content-Type' => 'text/plain'] 
     ], 
    ] 
]);

由于@hanshenrik正确地指出在他的评论中，狂饮客户端无法发送多重/相关要求，所以有些黑客是为了如Guzzle multipart/related content type feature request中所述。

$url = '/post'; 

    $headers = isset($options['headers']) ? $options['headers'] : []; 
    $body = new \GuzzleHttp\Psr7\MultipartStream($options['multipart']); 
    $version = isset($options['version']) ? $options['version'] : '1.1'; 
    $request = new \GuzzleHttp\Psr7\Request('POST', $url, $headers, $body, $version); 

    $modify['set_headers']['Content-Type'] = 'multipart/related; boundary=' . $request->getBody()->getBoundary(); 

    $request = \GuzzleHttp\Psr7\modify_request($request, $modify); 

    $response = $client->send($request);

在这个例子中，'headers'可能会设置Content-Type，以使它更清楚地回答OP，它回答了问题的这一部分。对？ –

@DanielStenberg对。 – Finwe

我并不熟悉guzzle（但知道它是什么），但我敢打赌这个代码导致'multipart/form-data'请求，而不是'multipart/related'请求，不管那是 – hanshenrik
