在 Youtube 上获取视频评论

Question

我正在使用 Google API，特别是 Youtube 的数据 API，使用视频 ID 获取视频上方的 cmets。我正在使用来自 Google 文档 here 的 python 示例，但出现以下错误：

Missing property "redirect_uris" in a client type of "web"

所以，这是我的 client_secrets_....json 文件：

{
    "installed": {
        "client_id":"xxxxxxxxxxxx-xxxxje3a7fk4jbs63g6m1a2mand4sa3h.apps.googleusercontent.com",
        "project_id":"progettotesicuozzo",
        "auth_uri":"https://accounts.google.com/o/oauth2/auth",
        "token_uri":"https://accounts.google.com/o/oauth2/token",
        "auth_provider_x509_cert_url":"https://www.googleapis.com/oauth2/v1/certs",
        "client_secret":"XXXXXXXXXXX",
        "redirect_uris":[
            "urn:ietf:wg:oauth:2.0:oob",
            "http://localhost"
        ]
    }
}

这是代码：

# Usage example:
# python test.py --videoid='<video_id>' --text='<text>'

        author = item["snippet"]["authorDisplayName"]
        text = item["snippet"]["textDisplay"]
        print("Comment by " + author + ": " + text)

    return results["items"]

if __name__ == '__main__':
    # The "videoid" option specifies the YouTube video ID that uniquely
    # identifies the video for which the comment will be inserted.
    argparser.add_argument("--videoid", help="Required; ID for video for which the comment will be inserted.")
    # The "text" option specifies the text that will be used as comment.
    #argparser.add_argument("--text", help="Required; text that will be used as comment.")
    args = argparser.parse_args()

    if not args.videoid:
        exit("Please specify videoid using the --videoid= parameter.")

    youtube = get_authenticated_service(args)
    # All the available methods are used in sequence just for the sake of an example.
    try:
        video_comment_threads = get_comment_threads(youtube, args.videoid)

        video_comments = get_comments(youtube, parent_id)
        except HttpError as e:
        print("An HTTP error " + str(e.resp.status) + " occurred:\n" +  json.dumps(str(e.content)))
    else:
        print("Inserted, listed, updated, moderated, marked and deleted comments.")

请问如何配置好我的json文件？

修复我的 Json 文件后，我现在遇到了这个错误：

An HTTP error 403 occurred:
{
    "error": {
        "errors": [
            {
                "domain": "global",
                "reason": "insufficientPermissions",
                "message": "Insufficient Permission"
            }
        ],
        "code": 403,
        "message": "Insufficient Permission"
    }
}

我使用网络 URL 中的 ID 请求了我的个人视频，但在提示我重定向到 redirect_uri 后，我收到了错误。

当您在google developer console 上创建项目时，系统会提示您下载 JSON 文件。您不应更改此文件，因为您似乎已删除了重定向 URI。重定向 URI 是作为浏览器凭据的一部分创建的。需要告诉服务器将响应返回到哪里。

例子：

{  
   "web":{  
      "client_id":"xxxxx-i6cjd1hkjntu5bkdkjj5cdnpcu4iju8p.apps.googleusercontent.com",
      "project_id":"daimto-tutorials-101",
      "auth_uri":"https://accounts.google.com/o/oauth2/auth",
      "token_uri":"https://accounts.google.com/o/oauth2/token",
      "auth_provider_x509_cert_url":"https://www.googleapis.com/oauth2/v1/certs",
      "client_secret":"xxxxx",
      "redirect_uris":[  
         "http://localhost/google-api-php-client-samples/Analytics/Oauth2.php",
         "http://localhost/google-api-php-client-samples/Calendar/Oauth2.php"
      ],
      "javascript_origins":[  
         "https://www.example.com"
      ]
   }
}

授权重定向 URI 用于来自 Web 服务器的请求。这 是用户在之后被重定向到的应用程序中的路径 他们已通过 Google 进行了身份验证。路径将附加 访问的授权码。必须有协议。不能 包含 URL 片段或相对路径。不能是公网IP 地址。

insufficientPermissions 意味着您正在与之进行身份验证的用户无权执行您尝试执行的操作。您通过用户和频道进行了身份验证。您只能访问该频道中的视频。
