egg-passport/egg-passport-local登录失败怎么获取错误信息？

[lijinshanmx]

const localStrategy = app.passport.authenticate('local', { successRedirect: '/', failureRedirect: '/signin', }); 怎么在登录失败的时候，传递错误信息，比如说用户名不存在或者密码错误等等，翻了好多issue和文档都找不到啊，egg-cnode里面的处理就是直接再次跳转登录页了，没办法给用户一直观的提示。。。failureRedirect回调只是一个简单的url地址，没办法获取到错误信息

egg-passport/egg-passport-local How do I get an error message when I log in failed?

const localStrategy = app.passport.authenticate('local', {     successRedirect: '/',     failureRedirect: '/signin',   }); How to pass the error message when the login fails, for example, the user name does not exist or the password is wrong, etc., many issues and documents can not be found, the processing inside the egg-cnode is to jump to the login page again. There is no way to give the user an intuitive reminder. . . The failureRedirect callback is just a simple url address, there is no way to get the error message.

现在我这边的解决是在passport校验user的时候，如果校验不通过，直接throw(401, errormsg),然后在中间件中catch(next())，然后判断code，再把error信息render到view上去。不知道这样是不是符合规范。。。但是好像能解决问题。

egg-passport-local 不要用了，直接自己写个 POST 的 Controller 处理
