PHP curl将Content-Type更改为application / x-www-form-urlencoded。不应该这样做 [英] PHP curl changes the Content-Type to application/x-www-form-urlencoded. Shouldn't do that

问题描述

我要从我使用PHP curl的服务器上传视频直接到YouTube。

我需要此请求格式：

  POST / feeds / api / users / default / uploads HTTP / 1.1 
 Host：uploads.gdata.youtube.com 
授权：承载ACCESS_TOKEN 
 GData-Version：2 
 X-GData-Key：key = adf15ee97731bca89da876c ... a8dc 
 Slug：video-test.mp4 
 Content-Type：multipart /有关; boundary =f93dcbA3
 Content-Length：1941255 
 Connection：close 
 
 --f93dcbA3 
 Content-Type：application / atom + xml; charset = UTF-8 
 
<？xml version =1.0？> 
< entry xmlns =http://www.w3.org/2005/Atom
 xmlns：media =http://search.yahoo.com/mrss/
 xmlns：yt =http://gdata.youtube.com/schemas/2007> 
< media：group> 
< media：title type =plain> Bad Wedding Toast< / media：title> 
< media：description type =plain> 
我在朋友的婚礼上给了一个糟糕的烤面包。 
< / media：description> 
< media：category 
 scheme =http://gdata.youtube.com/schemas/2007/categories.cat> People 
< / media：category> 
< media：keywords> toast，wedding< / media：keywords> 
< / media：group> 
< / entry> 
 --f93dcbA3 
 Content-Type：video / mp4 
内容传送编码：二进制
 
<二进制文件数据> 
 --f93dcbA3-- 
  

这是我有的：

  $ content = $ this-> buildRequestContent（）; 
 
 $ ch = curl_init（）; 
 
 $ curlConfig = array（
 CURLOPT_URL =>'http://uploads.gdata.youtube.com/feeds/api/users/default/uploads'，
 CURLOPT_POST => true，
 CURLOPT_RETURNTRANSFER => true，
 CURLOPT_BINARYTRANSFER => true，
 CURLOPT_POSTFIELDS => $ content，
 CURLOPT_HTTPHEADER，array（
 => sprintf（GoogleLogin auth =％s，$ this-> accessToken），
GData-Version=> 2，
X-GData-Key=& sprintf（key =％s，$ this-> developerKey），
Slug=> sprintf（％s，$ this-> video-> getFilename（）），
Content-Type=> sprintf（multipart / related; boundary = \％s\，$ this-> boundaryString），
Content-Length=> strlen （$ content），
Connection=>close
），
）; 
 
 curl_setopt_array（$ ch，$ curlConfig）; 
 
 $ result = curl_exec（$ ch）; 
  

转储结果显示curl更改了 Content-Type 到应用程序/ x-www-form-urlencoded ，当然不是由youtube支持。

我把我的二进制内容（视频）放入 CURLOPT_POSTFIELDS ，也许这是错误的，但我不知道如何设置请求体除此之外。 >

那么如何保留我设置的Content-Type呢？

解决方案

根据关于选项参数的文档部分，将HTTP方法设置为 POST 默认为内容类型设置为 application / x-www-form-urlencoded 。所以我的怀疑是，一次设置所有选项，导致您的 Content-Type 被覆盖。

我的建议是设置内容类型

  $ curlConfig = array（
 CURLOPT_URL => ;'http://uploads.gdata.youtube.com/feeds/api/users/default/uploads'，
 CURLOPT_POST => true，
 CURLOPT_RETURNTRANSFER => true，
 CURLOPT_BINARYTRANSFER => true，
 CURLOPT_POSTFIELDS => $ content，
）; 
 
 curl_setopt_array（$ ch，$ curlConfig）; 
 
 curl_setopt（$ ch，CURLOPT_HTTPHEADER，array（
'Authorization：'。sprintf（'GoogleLogin auth =％s'，$ this-> accessToken），
'GData -Version：2'，
'X-GData-Key：'。sprintf（'key =％s'，$ this-> developerKey），
'Slug：'。 '，$ this-> video-> getFilename（）），
'Content-Type：'。sprintf（'multipart / related; boundary =％s'，
 $ this-> ; boundaryString），
'Content-Length：'。strlen（$ content），
'Connection：close'
） 
  

I want to upload a video direct to Youtube from my server for which I am using PHP curl.

I need this request format:

POST /feeds/api/users/default/uploads HTTP/1.1
Host: uploads.gdata.youtube.com
Authorization: Bearer ACCESS_TOKEN
GData-Version: 2
X-GData-Key: key=adf15ee97731bca89da876c...a8dc
Slug: video-test.mp4
Content-Type: multipart/related; boundary="f93dcbA3"
Content-Length: 1941255
Connection: close

--f93dcbA3
Content-Type: application/atom+xml; charset=UTF-8

<?xml version="1.0"?>
<entry xmlns="http://www.w3.org/2005/Atom"
  xmlns:media="http://search.yahoo.com/mrss/"
  xmlns:yt="http://gdata.youtube.com/schemas/2007">
  <media:group>
    <media:title type="plain">Bad Wedding Toast</media:title>
    <media:description type="plain">
      I gave a bad toast at my friend's wedding.
    </media:description>
    <media:category

  </media:group>
</entry>
--f93dcbA3
Content-Type: video/mp4
Content-Transfer-Encoding: binary

<Binary File Data>
--f93dcbA3--

This is what I have:

$content = $this->buildRequestContent();

$ch = curl_init();

$curlConfig = array(
    CURLOPT_URL => 'http://uploads.gdata.youtube.com/feeds/api/users/default/uploads',
    CURLOPT_POST => true,
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_BINARYTRANSFER => true,
    CURLOPT_POSTFIELDS => $content,
    CURLOPT_HTTPHEADER, array(
        "Authorization" => sprintf("GoogleLogin auth=%s", $this->accessToken),
        "GData-Version" => 2,
        "X-GData-Key" => sprintf("key=%s", $this->developerKey),
        "Slug" => sprintf("%s", $this->video->getFilename()),
        "Content-Type" => sprintf("multipart/related; boundary=\"%s\"", $this->boundaryString),
        "Content-Length" => strlen($content),
        "Connection" => "close"
    ),
);

curl_setopt_array($ch, $curlConfig);

$result = curl_exec($ch);

Dumping the result shows me that curl changed the Content-Type to application/x-www-form-urlencoded which is of course not supported by youtube.

I put my binary content (the video) into CURLOPT_POSTFIELDS, maybe this is wrong, but I don't know how to set the request body other than that.

So how do I preserve my Content-Type that I set?

解决方案

According to the documentation section regarding the options' parameter setting the HTTP method to POST defaults to content type being set to application/x-www-form-urlencoded. So my suspicion is that setting all the options at once, results in your Content-Type being overwritten.
My suggestion would be to set the content type in a single statement, after you've set the method, i.e.

$curlConfig = array(
    CURLOPT_URL => 'http://uploads.gdata.youtube.com/feeds/api/users/default/uploads',
    CURLOPT_POST => true,
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_BINARYTRANSFER => true,
    CURLOPT_POSTFIELDS => $content,
);

curl_setopt_array($ch, $curlConfig);

curl_setopt($ch, CURLOPT_HTTPHEADER, array(
    'Authorization: ' . sprintf('GoogleLogin auth=%s', $this->accessToken),
    'GData-Version: 2',
    'X-GData-Key: ' . sprintf('key=%s', $this->developerKey),
    'Slug: ' . sprintf('%s', $this->video->getFilename()),
    'Content-Type: ' . sprintf('multipart/related; boundary="%s"',
                                  $this->boundaryString),
    'Content-Length: ' . strlen($content),
    'Connection: close'
));
