尝试将 Google API 与客户端机密文件和 OAuth 2.0 一起使用时出错

问题描述 投票:0回答:3

我只是不明白我在使用 YouTube API 时做错了什么,特别是 client secrets 文件.

我按照 google 开发者 网站上的步骤创建了一个 client secrets 文件

  1. 转到https://console.developers.google.com/
  2. 转到 API 管理器部分
  3. 转到凭据选项卡
  4. 添加凭据按钮 -> OAuth 2.0 客户端 ID
  5. 应用程序类型 -> Web 应用程序
  6. client secret文件现在可以下载了,所以我下载它并把它放在我的电脑上

现在,我尝试运行 google developers 网站上提供的这个基本代码片段https://developers.google.com/youtube/v3/code_samples/python#rate__like__a_video

    import httplib2
    import os
    import sys

    from apiclient.discovery import build
    from apiclient.errors import HttpError
    from oauth2client.client import flow_from_clientsecrets
    from oauth2client.file import Storage
    from oauth2client.tools import argparser, run_flow


    CLIENT_SECRETS_FILE = "C:\\Python27\\Projects\\YoutubeBot_client_secrets.json"

    # This variable defines a message to display if the CLIENT_SECRETS_FILE is
    # missing.
    MISSING_CLIENT_SECRETS_MESSAGE = "something went wrong."

    # This OAuth 2.0 access scope allows for full read/write access to the
    # authenticated user's account.
    YOUTUBE_READ_WRITE_SCOPE = "https://www.googleapis.com/auth/youtube"
    YOUTUBE_API_SERVICE_NAME = "youtube"
    YOUTUBE_API_VERSION = "v3"

    def get_authenticated_service(args):
      flow = flow_from_clientsecrets(CLIENT_SECRETS_FILE,
        scope=YOUTUBE_READ_WRITE_SCOPE,
        message=MISSING_CLIENT_SECRETS_MESSAGE)
      storage = Storage("%s-oauth2.json" % sys.argv[0])
      credentials = storage.get()
      if credentials is None or credentials.invalid:
        credentials = run_flow(flow, storage, args)
      return build(YOUTUBE_API_SERVICE_NAME, YOUTUBE_API_VERSION,
        http=credentials.authorize(httplib2.Http()))

    # Add the video rating. This code sets the rating to "like," but you could
    # also support an additional option that supports values of "like" and
    # "dislike."
    def like_video(youtube, video_id):
      youtube.videos().rate(
        id=video_id,
        rating="like"
      ).execute()

    if __name__ == "__main__":
      argparser.add_argument("--videoid", default="L-oNKK1CrnU", 
       help="ID of video to like.")
      args = argparser.parse_args()

      youtube = get_authenticated_service(args)
      try:
        like_video(youtube, "8hj6BK8WGtA" )
      except HttpError, e:
        print "An HTTP error %d occurred:\n%s" % (e.resp.status, e.content)
      else:
        print "%s has been liked." % args.videoid

我刚刚收到有关我的客户机密文件的错误(

MISSING_CLIENT_SECRETS_MESSAGE
错误):

SystemExit: something went wrong.

这就是根本原因-

---> 29     message=MISSING_CLIENT_SECRETS_MESSAGE)

我自己也遇到了这个问题,由于没有满意的答案,下面是我如何找到问题的根本原因: 删除

message
中的
flow_from_clientsecrets
参数应该会给你一个更具描述性的消息:

flow = flow_from_clientsecrets(
    CLIENT_SECRETS_FILE,
    scope=YOUTUBE_READ_WRITE_SCOPE,
    # message=MISSING_CLIENT_SECRETS_MESSAGE
)

例如,我自己实现了“缺少凭据文件”错误,但由于它似乎不是强制性的,我删除了它,并得到以下错误,这帮助我解决了真正的问题,因为该文件存在于文件系统,根据 Riccati 的回答:

oauth2client.clientsecrets.InvalidClientSecretsError: Invalid file format.
See https://developers.google.com/api-client-library/python/guide/aaa_client_secrets
Expected a JSON object with a single property for a "web" or "installed" application

注意这不仅可以解决 google api 的 youtube 组件的问题,还可以解决所有 api 的问题,就像我的 bigquery api 一样。

检查它是服务帐户密钥还是客户端密钥。 客户端密钥应以 {"installed":{"client_id".......

免责声明:这可能不是答案。

您是否尝试过这样的完整性检查:

if os.path.exists(CLIENT_SECRETS_FILE):
    print('yes, the client secrets file exists')
else:
    print('the client secrets file does not exist!')

也许实际问题更精彩。我之所以提供这个,是因为我总是犯这种愚蠢的错误……:)
