Picasa 图片/视频可恢复上传问题

Question

我正在尝试使用 google api 可恢复上传选项上传视频/图像。

如果我有 200MB 的文件，那么我必须进行 N 次块上传。 我的代码 N-1 次返回 308 状态代码（最后一次除外）。对于最后一块谷歌没有回应我（我的 php 服务器说“empty-reply-from-server”）

请帮助我哪里错了。

global $access_token;
$title = basename($videoPath);
$mimeType = mime_content_type($videoPath);
$content_length = getSize($videoPath);

代码：400 msg：文件过早结束。

读完这个话题，I found the solution 是给第一个会话请求一些东西。你不能离开它没有身体。

$xmldata =
'<entry xmlns="http://www.w3.org/2005/Atom">
    <title>cats.jpg</title>
    <summary>Real cat wants attention too.</summary>
    <category scheme="http://schemas.google.com/g/2005#kind" term="http://schemas.google.com/photos/2007#photo"/>
 </entry>';
$request  = new Google_Http_Request(
    "https://picasaweb.google.com/data/upload/resumable/media/create-session/feed/api/user/{$person->id}/albumid/6185252512807301377?alt=json&access_token=" .$token['access_token'],
    "POST",
    array('GData-Version' => 2,
        'Content-Type' => 'application/atom+xml',
        'MIME-Version' => '1.0',
        'Content-Length' => strlen($xmldata),
        'X-Upload-Content-Length' => $size,
        'X-Upload-Content-Type' => 'image/jpeg',
        'Slug' => 'xxxx.jpg',
        'Authorization' => "Bearer {$token['access_token']}"),
        $xmldata
);
$response = Google_Http_REST::doExecuteRaw($client, $request);

Slug 标头是必需的，但文件名将是 cats.jpg (xml)。
