Question

尝试在node.js上使用passport，passport-local和pasport-local-mongoose在我的网络应用程序中实现身份验证（使用cloud9）。

我的身份验证成功，但是当我尝试重定向到我的应用中的其他页面时（重定向到http://www.google.com正常工作！）我得到了这个堆栈跟踪（需要一个方向）：

TypeError: user.get is not a function

    at pass (/home/ubuntu/workspace/attendance/v4/node_modules/passport/lib/authenticator.js:347:9)

    at authenticate (/home/ubuntu/workspace/attendance/v4/node_modules/passport/lib/middleware/authenticate.js:349:7)

    at initialize (/home/ubuntu/workspace/attendance/v4/node_modules/passport/lib/middleware/initialize.js:53:5)

    at Function.process_params (/home/ubuntu/workspace/attendance/v4/node_modules/express/lib/router/index.js:330:12)

我的app.js如下：

var express = require('express'),
    app = express(),
    BodyParser = require("body-parser"),
    mongoose = require("mongoose"),
    students_class = require("./models/class"),
    passport= require("passport"),
    localstrategy=require ("passport-local"),
 //   passportlocalmongoose=("passport-local-mongoose"),
    student = require ("./models/student");
    mongoose.connect("mongodb://localhost/attendance");



app.set("view engine", "ejs");
app.use(express.static ("public"));
app.use(BodyParser.urlencoded({extended: true}));
app.use (require("express-session")( {
    secret: "liran",
    resave:false,
    saveUninitialized:false
}));
app.use(passport.initialize());
app.use(passport.session());
passport.use(new localstrategy(student.authenticate()));    
passport.serializeUser(student.serializeUser());
passport.deserializeUser(student.serializeUser());

// ====
// routes
// =====
app.get("/", function(req, res) {
    student.find({}, function(err, student) {
        if (err) {
            console.log(err);
        } else {
            res.render("home/index.ejs", {
                students: student
            });
        }

    });
});

app.post ("/login",passport.authenticate("local"),function (req,res) {
    res.redirect("/");

})

和我的用户模型：

var mongoose = require("mongoose"),
    passportlocalmongoose=require("passport-local-mongoose")
var studentsSchema = new mongoose.Schema({
    username: String,
    passport:String
   // name: String,
 //   image: String,
 //   description:String,
   // classes: [{ type: mongoose.Schema.Types.ObjectId, ref: 'class' }]
});


studentsSchema.plugin(passportlocalmongoose);
module.exports= mongoose.model("student", studentsSchema);

让我们检查堆栈跟踪以查看是否可以找到提示：

TypeError: user.get is not a function
    at /home/ubuntu/workspace/attendance/v4/node_modules/passport-local-mongoose/index.js:217:21
    at pass (/home/ubuntu/workspace/attendance/v4/node_modules/passport/lib/authenticator.js:347:9)
    at Authenticator.deserializeUser (/home/ubuntu/workspace/attendance/v4/node_modules/passport/lib/authenticator.js:352:5)
    ...

嗯，deserializeUser可能导致问题。

让我们看看它是如何设置的：

passport.serializeUser(student.serializeUser());
passport.deserializeUser(student.serializeUser());

也许您打算将student.deserializeUser()传递给passport.deserializerUser()？

使用passport-local和passport-local-mongoose进行身份验证错误
