Node.js 内部OAuth错误：无法获取用户配置文件NodeJs+；passport-google-oAuth2

我正在学习使用passport-google-oauth20进行身份验证。当我尝试使用Google+注册用户时，在提交请求失败后，我会不断收到此错误消息（InternalOAuthError:failed to fetch user profile）

我尝试了这个解决方案：

我启用了Google+API并等待

经过几次改变，它对我起了作用

在passport.deserializeUser（）方法中，应该使用“user”而不是“user”

在passport.use（新谷歌策略…）中，userProfileURL值有一个输入错误

userProfileURL:“https://www.googleapis.com/oauth2/v3/userinfo"

请尝试这些更改。希望有帮助。

注意：saveUninitialized的默认值也是true。在您的场景中，该值应该为false，但true也没有坏处。
