Question

我正在使用Google API，特别是Youtube的数据API，使用视频ID在视频上方发表评论。我正在使用来自Google文档here的python示例，但我遇到以下错误：

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>'

import httplib2
import os
import sys
import json

from apiclient.discovery import build_from_document

def get_authenticated_service(args):
    flow = flow_from_clientsecrets(CLIENT_SECRETS_FILE, scope=YOUTUBE_READ_ONLY_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)

    with open("youtube-v3-discoverydocument.json", "r", encoding="utf8") as f:  
        doc = f.read()
        return build_from_document(doc, http=credentials.authorize(httplib2.Http()))

    results = youtube.commentThreads().list(
        part="snippet",
        videoId=video_id,
        textFormat="plainText"
    ).execute()

    for item in results["items"]:
        comment = item["snippet"]["topLevelComment"]
        author = comment["snippet"]["authorDisplayName"]
        text = comment["snippet"]["textDisplay"]
        print("Comment by " + author + ": " + text)

    return results["items"]


 def get_comments(youtube, parent_id):
    results = youtube.comments().list(
        part="snippet",
        parentId=parent_id,
        textFormat="plainText"
    ).execute()

    for item in results["items"]:
        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)
        parent_id = video_comment_threads[0]["id"]
        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.")

我该如何配置好我的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"
    }
}

我已经使用网址中的ID请求了我的个人视频，但在我被提示进入redirect_uri之后，我收到了错误。

在google developer console上创建项目时，系统会提示您下载JSon文件。您不应该更改此文件，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。

示例：

{  
   "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。这个是您的应用程序中用户被重定向到之后的路径他们已通过Google验证。路径将附加访问的授权代码。必须有一个协议。不能包含URL片段或相对路径。不能是公共IP 地址。

insufficientPermissions意味着您要进行身份验证的用户无权执行您尝试执行的操作。您已通过用户和频道进行身份验证。您只能访问该频道中的视频。
