使用KoaJS和PassportJS自动登录用户 [英] Automatically logging in a user with KoaJS and PassportJS

问题描述

我正在尝试使用 PassportJS 自动登录用户.

I'm trying to automatically log in a user with PassportJS.

这是我当前的代码:

myRouter.get('/signin', function* (next) {

    user = {...};

    var res = this.res; // needed for the function below
    this.req.login(user, function(err) {
        if (err)
            console.log('error logging in user - '+err);
        return res.redirect('/'); // <--- line 439
    });
});

但是当我运行它时，出现错误:

But when I run it, I get the error:

  error logging in user - TypeError: undefined is not a function
  TypeError: undefined is not a function

推荐答案

一个简短的半derp瞬间，我意识到要在koa中重定向，它不使用res而是使用this，您必须执行以下操作:

A quick semi-derp moment and I realize to redirect in koa it does not use res but this, you must do the following:

var res = this; // needed for the next function
this.req.login(user, function(err) {
    if (err)
        console.log('error logging in user - '+err);
    return res.redirect('/');
});
