done 不是 passport js 中的函数错误

Question

我正在使用 passportjs 进行身份验证和会话。我从 mysql 获取用户名，从客户端获取输入字段，但是当在验证时调用 done 时，我得到 done is not a function.

server.js :

    var express = require('express');
var app = express();
var path = require('path');
var bodyParser = require('body-parser');
var passport = require('passport');
var LocalStrategy = require('passport-local').Strategy;
var cookieParser = require('cookie-parser');

// app.use(app.router);
app.use(passport.initialize());

app.use(passport.session());
app.use(bodyParser.json());

app.use(express.static(__dirname+"/staticFolder"));

var mysql = require('mysql');
var connection = mysql.createConnection({
    host:'127.0.0.1',
    user:'root',
    password:'sdf',
    database:'abc'
});
connection.connect(function(err){
    if(err){
        throw err;
    }
});

passport.serializeUser(function(user,done){
    console.log("serializeUser" + user);
    done(null,user.body.username);
})
passport.deserializeUser(function(id, done) {
     done(null, user);

 });


passport.use(new LocalStrategy({
    passReqToCallback : true

},function(username, password, done) {

    connection.query("select * from employeedetails where empid = "+username.body.username,function(err,user,w){
    if(err)
    {
        console.log(err+"fml $$$$$$$$$$");  
         return done(err);           
    }
    if(username.body.password == user[0].password){
    console.log(user[0].empid+" login");
     return done(null,user[0].empid);
  }
  else{
     return done(null,false,{message: 'Incorrect password'});
   console.log(user[0].empid+" fml"); 
  }

  });

}));



app.get('/',function(request,response){
    response.sendFile(__dirname+"/staticFolder/view/");
})

app.post('/saveEmployeeDetails',function(request,response){
    response.end();
})

app.get('/login',function(request,response){ //the file sent when /login is requested
    response.sendFile(__dirname+"/staticFolder/view/login.html");
})

app.post('/loginCheck',passport.authenticate('local', {
            successRedirect : '/', 
            failureRedirect : '/login', 
            failureFlash : true // 
    }),
        function(req, res) {
            console.log("hello");
            res.send("valid");
            res.redirect('/');
    });

能否请您参考下面的link，其中谈到了同样的错误

https://github.com/jaredhanson/passport/issues/421

它说当您删除 (passReqToCallBack: true) 选项时不会发生错误

Answer 2

在您的 passport.js 配置文件中，passport.use(new LocalStrategy) 回调功能取决于您使用的策略，您将需要一定数量的 arguments.I 只需添加 "req" 作为我的第一个参数。

passport.use(new LocalStrategy({
    passReqToCallback: true
},
function (req, apikey, done) {
    //ADD REQ UP HERE
    process.nextTick(function () {
        findByApiKey(apikey, function (err, user) {
            if (err) {
                return done(err);
            }
            if (!user) {
                return done(null, false, {
                    message: 'Unknown apikey : ' + apikey
                });
            }
            return done(null, user);
        })
    });
}));

可能是函数中缺少参数的问题。
这是 passport-openidconnect 策略的示例源代码：

// Using 'passport-openidconnect' strategy
var OpenidConnectStrategy = require('passport-openidconnect');

var strategy = new OpenidConnectStrategy(
  {
    issuer: process.env.OAUTH_ISSUER,
    authorizationURL: process.env.OAUTH_AUTHORIZATION_URL,
    tokenURL: process.env.OAUTH_TOKEN_URL, 
    userInfoURL: process.env.OAUTH_USERINFO_URL,
    clientID: process.env.OAUTH_CLIENT_ID,
    clientSecret: process.env.OAUTH_CLIENT_SECRET,
    callbackURL: process.env.OAUTH_CALLBACK_URL,
  },
  // Parameters in the function should be appropriate with the strategy
  function (issuer, sub, profile, accessToken, refreshToken, done) {
    return done(null, profile);
  }
);

done 不是 passport js 中的函数错误

done is not a function error in passport js

node.js

express

passport.js
