节点JS：登录不工作

Question

我在Node上使用了Express .hbs模板。我使用护照来验证特定用户。我在MongoDB中使用的数据库。

这是我的注册路线：

var express = require('express');
var router = express.Router();
var passport = require('passport');
var userServices = require('../services/user-services');

router.get('/', function(req, res, next) {

    var vm = {
    title: 'Join this web',
    };
  res.render('signup', vm);
});

router.post('/', function(req, res, next) {
  userServices.addUser(req.body, function(err){
    if(err){
    var vm = {
      title: 'Create an account',
      input: req.body,
      error: err
    };
    delete vm.input.password;
    return res.render('signup', vm);
  }
      req.login(req.body, function(err) {
      res.redirect('/profile');
    });
   });
});
router.post('/login', passport.authenticate('local'), function(req, res, next){
  res.redirect('/profile');
});

module.exports = router;

这是我的登录路线：

var express = require('express');
var router = express.Router();
router.get('/', function(req, res, next) {
  if (req.user) {
    return res.redirect('/profile');
  }
  res.render('login', { title: 'Login' });
});

module.exports = router;

我已在passport-congig文件中定义了护照的配置：

module.exports=function(){
    var passport = require('passport');
    var passportLocal = require('passport-local');
    var userServices = require('../services/user-services');

    passport.use(new passportLocal.Strategy({usernameField: 'email'}, function(email, password, next) {
        userServices.findUser(email, function(err, user){
            if(err){
                return next(err);
            }
            if(!user||user.password!==password){
                return next(null, null);
            }
            next(null, user);
        });
    }));

    passport.serializeUser(function(user, next){
        next(null, user.email);
    });

    passport.deserializeUser(function(user, next){
        userServices.findUser(email, function(err, user){
            next(err, user);
        });
    });
};

此外，这是我的app.js与护照相关的代码：

var passportConfig = require('./auth/passport-config');
passportConfig();

var app = express();

app.use(expressSession({
    secret:'trawel man',
    saveUninitialized: false,
    resave: false
}));

app.use(passport.initialize());
app.use(passport.session());

以下是我收到的错误的堆栈跟踪：

Error: Not Found

这是我在服务器控制台上得到的：

POST /login 404 32.453 ms - 2847

我不知道为什么这不起作用。我是Node的新手。有人帮助我。

您错过了@model MVC_myfirst_Mvcapplication.Models.Person @{ ViewBag.Title = "Create"; } <h2>Create</h2> <script src="@Url.Content("~/Scripts/jquery.validate.min.js")" type="text/javascript"></script> <script src="@Url.Content("~/Scripts/jquery.validate.unobtrusive.min.js")" type="text/javascript"></script> @using (Html.BeginForm()) { @Html.ValidationSummary(true) <fieldset> <legend>Person</legend> <div class="editor-label"> @Html.LabelFor(model => model.First) </div> <div class="editor-field"> @Html.EditorFor(model => model.First) @Html.ValidationMessageFor(model => model.First) </div> <div class="editor-label"> @Html.LabelFor(model => model.Last) </div> <div class="editor-field"> @Html.EditorFor(model => model.Last) @Html.ValidationMessageFor(model => model.Last) </div> <div class="editor-label"> @Html.LabelFor(model => model.Birthdate) </div> <div class="editor-field"> @Html.EditorFor(model => model.Birthdate) @Html.ValidationMessageFor(model => model.Birthdate) </div> <p> <input type="submit" value="Create" /> </p> </fieldset> } <div> @Html.ActionLink("Back to List", "Index") </div> 的路线，这就是为什么您的最终“未找到”路线被调用的原因。

使用

添加路线

/profile

并且不会抛出该错误

编辑：

好像你在尝试登录时遇到错误，而不是之后。那是因为您router.get('/profile', function (req, res, next) { var vm = { name : req.user ? req.user.name:null }; res.render('profile', vm); }) 的路线位于错误的文件中。在您的登录路由文件中，添加以下内容：

POST login

（确保导入依赖项）

从注册路线中删除router.post('/', passport.authenticate('local'), function(req, res, next){ res.redirect('/profile'); }); 。
