node.js - 无法调用 Passport 本地策略

Question

我是 Angular 5 的初学者，目前正在开发一个应用程序。所以在登录模块中，passport本地策略不起作用，passport.authenticate函数不起作用，我似乎在代码中找不到问题。

现在我不知道出了什么问题，因为控制台上没有错误，而且每次都返回 null。这就是为什么我复制粘贴大量代码。

代码附在下面。

这里只是我的两分钱......无论你在哪里返回完成(空......) Passport.use()，您可以针对不同的 done() 调用将 null 值替换为不同的错误，并查看调用哪一个以及原因。
