未知的策略「本地」，nodejs和護照

Question

我檢查了這個常見的isue的答案，但它似乎是它的一個個案，我不能找出wth是錯誤的與我的代碼。在這裏，我首先設置了本地註冊，然後登錄，當我嘗試登錄時，無論輸入什麼內容，我都會收到「未知策略」本地錯誤。

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

    // expose this function to our app using module.exports 
    module.exports = function(passport) { 
     passport.serializeUser(function(user, done) { 
     done(null, user.id); 
     }); 

     // used to deserialize the user 
     passport.deserializeUser(function(id, done) { 
     connection.query("select * from users where id = "+id,function(err,rows){ 
      done(err, rows[0]); 
     }); 
     }); 

     passport.use('local-signup', new LocalStrategy({ 
      // by default, local strategy uses username and password, we will override with email 
      usernameField : 'email', 
      passwordField : 'password', 
      passReqToCallback : true // allows us to pass back the entire request to the callback 
     }, 
     function(req, email, password, done) { 

      connection.query("select * from users where email = '"+email+"'",function(err,rows){ 
      console.log(rows); 
      console.log("above row object"); 
      if (err) 
        return done(err); 
      if (rows.length) { 
        return done(null, false, req.flash('signupMessage', 'That email is already taken.')); 
       } else { 

      // if there is no user with that email 
        // create the user 
        var newUserMysql = new Object(); 

      newUserMysql.email = email; 
        newUserMysql.password = password; // use the generateHash function in our user model 

      var insertQuery = "INSERT INTO users (email, password) values ('" + email +"','"+ password +"')"; 
       console.log(insertQuery); 
      connection.query(insertQuery,function(err,rows){ 
      newUserMysql.id = rows.insertId; 

      return done(null, newUserMysql); 
      }); 
       } 
     }); 
     })); 

     passport.use('local-login', new LocalStrategy({ 
      // by default, local strategy uses username and password, we will override with email 
      usernameField : 'email', 
      passwordField : 'password', 
      passReqToCallback : true // allows us to pass back the entire request to the callback 
     }, 
     function(req, email, password, done) { // callback with email and password from our form 

      connection.query("SELECT * FROM `users` WHERE `email` = '" + email + "'",function(err,rows){ 
      if (err) 
        return done(err); 
      if (!rows.length) { 
        return done(null, false, req.flash('loginMessage', 'No user found.')); // req.flash is the way to set flashdata using connect-flash 
       } 

      // if the user is found but the password is wrong 
       if (!(rows[0].password == password)) 
        return done(null, false, req.flash('loginMessage', 'Oops! Wrong password.')); // create the loginMessage and save it to session as flashdata 

       // all is well, return successful user 
       return done(null, rows[0]);  

     }); 



     })); 

    } 


    app.use(passport.initialize()); 


    ... 

編輯：忘了寫這部分。林與調用它：

app.post('/login', 
    passport.authenticate('local', { successRedirect: '/', 
            failureRedirect: '/login', 
            failureFlash: true }) 
);

既然你定義的策略爲passport.use('local-login', ...)，我想你應該在你的端點定義中使用passport.authenticate('local-login')（未示出）。
