PHP代理 - 使用cURL上传文件

问题描述：

I'm currently building an application written in AngularJS with a Laravel based API for the backend, data is passed via a simple PHP proxy to keep my API key secure(ish).

For POST requests the proxy simply json_decode PHPs input stream (php://input) as Angular serialises POST data to JSON, passes it through http_build_query then forwards it via cURL to the API - so far, it's been working flawlessly.

I've managed to get the file over to the proxy - however, as it's sent with multipart/form-data headers, it's only available in $_FILES and not the input stream.

Relevant snippets from the proxy below:

function curlRequest($url, $post = false, $data = null)
{
  $ch = curl_init();

  curl_setopt($ch, CURLOPT_URL, $url);
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

  if($post == true) {
    curl_setopt($ch, CURLOPT_POST, 1);
    curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($data));
  }

  $data = curl_exec($ch);
  $httpcode = curl_getinfo($ch, CURLINFO_HTTP_CODE);

  curl_close($ch);
}

$data = json_decode(file_get_contents('php://input'), true);
$data['api_key'] = API_KEY;

// File data available here!
var_dump($_FILES);

$result = curlRequest(URL, true, $data);

The problem I'm having, I'm unsure how to correctly POST the file to the API endpoint once I've got it in $_FILES.

Any help would be greatly appreciated!

我正在构建一个用AngularJS编写的应用程序，后端使用基于Laravel的API，数据通过简单的PHP代理保证我的API密钥安全（ish）。 p>

我已成功将文件传递给代理 - 但是，因为它是通过 multipart / form-data code>标头发送的，它只能在 $ _ FILES code>中使用，而不是输入流。 p >

下面代理的相关代码段： p>


  function curlRequest（$ url，$ post = false，$ data = null）
 {
  $ ch = curl_init（）; 
 
 curl_setopt（$ ch，CURLOPT_URL，$ url）; 
 curl_setopt（$ ch，CURLOPT_RETURNTRANSFER，true）; 
 
 if（$ post == true）{
 curl_setopt  （$ ch，CURLOPT_POST，1）;

 $ data = curl_exec（$ ch）; 
 $ httpcode = curl_getinfo（$ ch，CURLINFO_HTTP_CODE）; 
 
 curl_close（$  ch）; 
} 
 
 $ data = json_decode（file_get_contents（'php：// input'），true）; 
 $ data ['api_key'] = API_KEY; 
 
 //文件数据可用 在这里！
var_dump（$ _ FILES）; 
 
 $ result = curlRequest（URL，true，$ data）;

 我遇到的问题， 我不确定如何在 $ _ FILES  code>中将文件正确地发布到API端点。 p> 
 
 
任何帮助都将不胜感激！

This may send files over as well :

$data = json_decode(array_merge($_REQUEST, $_FILES));
$data['api_key'] = API_KEY;

// File data available here!
var_dump($_FILES);

$result = curlRequest(URL, true, $data);
