Google OAuth 令牌请求 returns "invalid_client": "Unauthorized"

Question

正在尝试让 OAuth2 Google 登录正常工作，这是我的应用发出的原始请求：

方法：POST

URL: https://www.googleapis.com/oauth2/v3/token

Headers: Content-Type: application/x-www-form-urlencoded

值：

client_id: XXX-0123456789abcdef0123456789abcdef.apps.googleusercontent.com

client_secret: A1b2C3d4E5f6G7h8I9j0K1l2M

code: 1/A1b2C3d4E5f6G7h8I9j0K1l2M3n4O5p6Q7r8S9t0U1v

grant_type: authorization_code

redirect_uri: http://localhost:5000/callback/google/

这是回复：

状态：401 Unauthorized

Body:

{
    "error": "invalid_client",
    "error_description": "Unauthorized"
}

已验证这正是我的应用程序正在发出的请求/响应（Python 应用程序使用 Flask 和 rauth），并且已验证我可以使用 Postman 重现完全相同的请求/响应。

根据其他线程中的说明，我在 Google API 控制台中完成了以下所有操作：

在 "OAuth consent screen" 设置中，将 "Product name" 设置为不同于 "Project name"
同样在 "OAuth consent screen" 设置中，double-check 已设置电子邮件
启用 Google+ API
启用 Gmail API
重新创建客户端 ID/密码
Double-check 客户端 ID / 秘密值中没有前导或尾随空格，我已从 API 控制台

无论我做什么，仍然得到与 "invalid_client": "Unauthorized" 相同的响应。

我们将不胜感激。我正在尝试在我的应用程序中设置 OAuth2-powered "Log in with X" 功能，让 Facebook 和 Twitter 正常工作，也想让 Google 正常工作，但如果我不能解决这个问题，那么我'恐怕我将不得不放弃 Google auth.

Answer 1

无效客户端 表示您使用的客户端 ID 或客户端密码无效。它们必须是您从 Google 开发者控制台下载的。

提示：您可能需要考虑使用 Google python client 库，它会为您完成所有繁重的工作。

from __future__ import print_function
import pickle
import os.path
from googleapiclient.discovery import build
from google_auth_oauthlib.flow import InstalledAppFlow
from google.auth.transport.requests import Request

# If modifying these scopes, delete the file token.pickle.
SCOPES = ['https://www.googleapis.com/auth/drive.metadata.readonly']

def main():
    """Shows basic usage of the Drive v3 API.
    Prints the names and ids of the first 10 files the user has access to.
    """
    creds = None
    # The file token.pickle stores the user's access and refresh tokens, and is
    # created automatically when the authorization flow completes for the first
    # time.
    if os.path.exists('token.pickle'):
        with open('token.pickle', 'rb') as token:
            creds = pickle.load(token)
    # If there are no (valid) credentials available, let the user log in.
    if not creds or not creds.valid:
        if creds and creds.expired and creds.refresh_token:
            creds.refresh(Request())
        else:
            flow = InstalledAppFlow.from_client_secrets_file(
                'credentials.json', SCOPES)
            creds = flow.run_local_server(port=0)
        # Save the credentials for the next run
        with open('token.pickle', 'wb') as token:
            pickle.dump(creds, token)

    service = build('drive', 'v3', credentials=creds)

    # Call the Drive v3 API
    results = service.files().list(
        pageSize=10, fields="nextPageToken, files(id, name)").execute()
    items = results.get('files', [])

    if not items:
        print('No files found.')
    else:
        print('Files:')
        for item in items:
            print(u'{0} ({1})'.format(item['name'], item['id']))

if __name__ == '__main__':
    main()

刷新 https://console.cloud.google.com/apis/credentials 上的客户端机密文件并删除令牌 pickle 文件夹
