Python 3.x 如何修复重定向uri与Google的重定向uri不匹配

当我试图访问谷歌日历api时，我遇到了这个错误

错误：

错误400:重定向\u uri\u不匹配 请求中的重定向URI，http://localhost:37461/，与为OAuth客户端授权的不匹配。要更新授权重定向URI，请访问：

上面提到的端口

http://localhost:37461/

总是在变化

这就是我如何设置我的

凭证.json

{
  "web": {
    "client_id": "<id>.apps.googleusercontent.com",
    "project_id": "stunning-surge-291419",
    "auth_uri": "https://accounts.google.com/o/oauth2/auth",
    "token_uri": "https://oauth2.googleapis.com/token",
    "auth_provider_x509_cert_url": "https://www.googleapis.com/oauth2/v1/certs",
    "client_secret": "***",
    "redirect_uris": ["http://localhost:3000/create"],
    "javascript_origins": ["http://localhost:3000"]
  }
}

我还在控制台中设置了重定向URL：

有人能帮我吗？

实际上，您可以指定要修复的重定向uri的端口，以便将您重定向到正确的url，如果您已经被重定向到http://localhost:37461/

：37461

当您不指定特定端口时，此数字是随机的，正如@Tanaike提到的，您需要将端口修复为3000，如屏幕截图所示。

---

creds=flow。运行本地服务器（端口=3000）

在您的情况下，如何从

http://localhost:3000/create

至

http://localhost:3000

脚本将从

creds=flow.run\u local\u server（port=0）

修改为

creds=flow.run\u local\u server（port=3000）

。顺便说一下，从您的

credentials.json

和图像来看，似乎

http://localhost

未保存。因此，当您修改重定向URL时，请单击“保存”按钮。请小心这个。如果这个评论对你的情况没有帮助，我道歉。@Tanaike的建议对你的问题有用吗？
