YouTube的API - 直接上传 - 413请求实体过大(YouTube API - Dir

我一直在试图将视频上传到通过直接上传YouTube的API。我终于破解了OAuth的过程，我有一个有效的令牌。我真的只需要做两件事情与YouTube，验证和上传。我不是浏览，或者使用任何其他功能。用户视频上传到这个网站，我送他们到YouTube上播放。

我觉得我对我自己来的方式80-90％在这里，所以我不想放弃这一点，并使用Zend库，谷歌提供。

问题：当我发送请求我得到这样的回应：

HTTP/1.1 413 Request Entity Too Large
Content-Type: text/html; charset=UTF-8
Content-Length: 171
Date: Thu, 18 Apr 2013 18:33:22 GMT
Expires: Thu, 18 Apr 2013 18:33:22 GMT
Cache-Control: private, max-age=0
X-Content-Type-Options: nosniff
X-Frame-Options: SAMEORIGIN
X-XSS-Protection: 1; mode=block
Server: GSE
Connection: close

如果我打开的警告，我也得到一个破裂的管道警告，这可能只是想通过封闭的上传数据的代码/拒绝连接。

我的要求是这样的：

POST /feeds/api/users/default/uploads HTTP/1.1 
Host: gdata.youtube.com Connection: close 
User-Agent: PHP Accept-encoding: identity 
Authorization: Bearer <TOKEN IS HERE> 
GData-Version: 2.0 
X-GData-Key: key=<MYKEYISHERE>
Slug: throwing_can.mp4 
Content-Type: multipart/related; boundary="5170429d1b193" 
Content-Length: 3920610

随着文件本身分块并写入流。

function ytapi_write_file($handle, $path, $chunksize = 8192){
    $filehandle = fopen($path, 'r');
    while(!feof($filehandle)){
        fwrite($handle, fread($filehandle, $chunksize));
    }
    fclose($filehandle);
    $filehandle = null;
}

function ytapi_write($handle, $request){
    fwrite($handle, $request);
    return $request;
}

像这样。

ytapi_write($handle, $start); //This writes the header.
ytapi_write_file($handle, $path, 8192); //This writes the file raw/binary.
ytapi_write($handle, $end); //This writes the final boundary.

另外，我用这个标题信息：

$_header = array(
    'Host'=>'gdata.youtube.com',
    'Connection'=>'close',
    'User-Agent'=>'PHP',
    'Accept-encoding'=>'identity'
);

任何想法，我做错了什么？如果需要，我可以提供更多的信息。我上传的文件多一点3MB，就是坐在问题的服务器上的文件。我已经验证的位置是否正确。

UPDATE

更改为uploads.gdata.youtube.com

现在，我得到这个错误信息：

Host: uploads.gdata.youtube.com
Connection: close
User-Agent: PHP

这是我实现：

$data = '<?xml version="1.0"?>

        <media:category scheme="http://gdata.youtube.com/schemas/2007/categories.cat">Music</media:category>

$headers = array(
    'Authorization: GoogleLogin auth=' . $auth,
    'GData-Version: 2',
    'X-GData-Key: key=<KEY>',
    'Slug: ' . basename($videoPath)
);

$tmpfname = tempnam("/tmp", "youtube");
$handle = fopen($tmpfname, "w");
fwrite($handle, $data);
fclose($handle);

$post = array(
    'xml' => '@' . $tmpfname . ";type=application/atom+xml",
    'video' => '@' . $videoPath . ";type=video/mp4",
);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "uploads.gdata.youtube.com/feeds/api/users/default/uploads");
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$content = curl_exec($ch);
curl_close($ch);
