在real s中测试YouTube数据API

Question

我正在尝试使用YouTube数据API在Python中搜索视频。我已经阅读了完整的教程，我能够从本地机器授权和验证用户，但是当我在服务器上部署相同的代码时，我在日志中得到下面列出的错误。浏览器显示“内部服务器错误”

我在试来自This guide from Google的女生

我已经在googleapi控制台中替换了重定向的URL路径。你知道吗

下面是我的密码。你知道吗

def oauth2callback():
  # Specify the state when creating the flow in the callback so that it can
  # verified in the authorization server response.
  state = flask.session['state']

  flow = google_auth_oauthlib.flow.Flow.from_client_secrets_file(
      CLIENT_SECRETS_FILE, scopes=SCOPES, state=state)
  flow.redirect_uri = flask.url_for('oauth2callback', _external=True)

  # Use the authorization server's response to fetch the OAuth 2.0 tokens.
  authorization_response = flask.request.url
  flow.fetch_token(authorization_response=authorization_response)

  # Store credentials in the session.
  # ACTION ITEM: In a production app, you likely want to save these
  #              credentials in a persistent database instead.
  credentials = flow.credentials
  flask.session['credentials'] = credentials_to_dict(credentials)

  return flask.redirect(flask.url_for('test_api_request'))

使用命令flow.fetch_token获取令牌时出错
