我已经使用 Google App Engine 应用程序中的 YouTube 数据 API 5 个月了，但没有收到服务不可用、503 错误响应。但是今天，我得到了这个：

YouTubeError: {
    'status': 503,

}

我正在使用 YouTube 上传用户的视频，也用于显示现有视频（用户只输入视频 URL）。有人知道它不起作用的可能原因吗？

我正在使用 gdata python 库。我在视频模型中定义了 yt_service 属性：

def yt_service(self):
    try:
        return self._yt_service
    except AttributeError:
        yt_service = gdata.youtube.service.YouTubeService()            
        yt_service.developer_key = settings.SYNCR_YT_DEVKEY
        yt_service.email = settings.SYNCR_YT_EMAIL
        yt_service.password = settings.SYNCR_YT_PASS
        yt_service.ProgrammaticLogin()
        self._yt_service = yt_service
        return yt_service

然后在创建上传表单时，查看调用yt_service.GetFormUploadToken以检索上传令牌。在这里失败了。
