Youtube Oauth 2.0 API 视频上传失败

Question

所以我设法构建了 oauth 2.0 youtube 视频上传，但每次我上传视频时，我都会收到 HTTP 400 错误，请求无效。

但最奇怪的是，视频上传到 youtube 时出现：失败（上传中止）。

我没有使用任何框架，因为谷歌还没有任何 oauth 2.0，所以我自己构建了所有代码。

而且我确实设法发送了 cmets 和其他东西......唯一的问题是视频上传本身。

我的代码：

public function uploadVideo($video, $title, $description, $category, $keywords) {
$url       = 'http://uploads.gdata.youtube.com/feeds/api/users/FacebookDevelopersIL/uploads';
$boundary  = uniqid();

$accessToken = $this->refreshAccessToken("13", "11313", 'REFRESHTOKEN');
$xmlString = "<?xml version='1.0'?><entry xmlns='http://www.w3.org/2005/Atom' xmlns:media='http://search.yahoo.com/mrss/'  xmlns:yt='http://gdata.youtube.com/schemas/2007'><media:group><media:title type='plain'>".$title."</media:title><media:description type='plain'>".$description."</media:description> <media:category scheme='http://gdata.youtube.com/schemas/2007/categories.cat'>".$category."</media:category><media:keywords>".$keywords."</media:keywords></media:group></entry>";
$videoData = file_get_contents($video);

$headers   = array(
    'POST /feeds/api/users/FacebookDevelopersIL/uploads HTTP/1.1',
    'Host: uploads.gdata.youtube.com',
    'Authorization: Bearer '.$accessToken,
    'GData-Version: 2',
    'X-GData-Key: key='.YOUTUBE_SRM_DEVELOPER_KEY,
    'Slug: IMG_0047.mp4',
    'Content-Type: multipart/related; boundary='.$boundary,
    'Content-Length:'.strlen($videoData),
    'Connection: close'
);

$postData  = "--".$boundary . "\r\n"
    ."Content-Type: application/atom+xml; charset=UTF-8\r\n\r\n"
    .$xmlString . "\r\n"
    ."--".$boundary . "\r\n"
    ."Content-Type: video/mp4\r\n"
    ."Content-Transfer-Encoding: binary\r\n\r\n"
    .$videoData . "\r\n"
    ."--".$boundary . "--";

$ch  = curl_init($url);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $postData);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 0);
$response = curl_exec($ch);
curl_close($ch);
Trace::dump($response); }

我得到的错误：HTTP/1.1 400 Bad Request Server: HTTP Upload Server Built on May 7 2012 18:16:42 (1336439802) Content-Type: text/html; Charset = UTF-8 X-GUPLOODER-UNENB2UQ7CHCF6RS4BCAMU18CHAF3GNKJQSF6U_DK2QB4WR9GHAOTL_-IUEJITGEAD-GH-1FPJCCKE1Z68TAXOOPS2VYIGMCWW69A日期：THU，2012年5月11日11:55:24 GMT Pragma：No-Cache到期：FRI，20190 00:00 GMT缓存-控制：无缓存，无存储，必须重新验证内容长度：15 连接：关闭

无效请求

谢谢大家！

我注意到一些事情：对 POST 和 Host 标头进行硬编码是一种糟糕的形式，因为 curl 会自动为您处理它们。我怀疑部分问题是在 $videoData 和最后一个边界标记之间插入了回车/换行符。这将被解释为视频文件的一部分。您所需要的只是换行符作为行分隔符。也许回车会使视频文件无效？

也许 curl_setopt($ch, CURLOPT_VERBOSE, true) 会提供一些照明。

这对我有用（在 Linux 主机上）：

        log_msg("Obtaining access token");
