使用Passport.js的login系统始终执行“failureRedirect”（nodejs）
我正在做一个教程，我卡在login区域。 当我使用Passport.jslogin时，它始终在validation中执行“failureRedirect”。
尝试debuggingreplacerouter.post（'login'）路由后，我收到以下消息：
错误：null用户：false信息：{“message”：“Missing credentials”}
在阅读一些论坛后，我认为这个问题可能与body-parser有关。 我一直在试图解决这个问题，但我还没有成功。 我会感激最有经验的node.js程序员的帮助。
该项目的结构是：app.js routes：users.js models：user.js
user.js的

谢谢你的帮助 ：）
首先..请尝试模块化代码。 将function放在不同的文件中可以帮助您更快地跟踪错误。 其次为什么有两个POST调用login路线？ 删除第一个，不需要发送jsonParser。 哟已经声明序列化和反序列化的用户。 所以护照会处理rest。
