Passport.JS 卡在重定向答案

【问题描述】：

我的 Express 应用程序中的 Passport.JS 出现问题，更具体地说是注册/登录的成功重定向。用户名/密码没有问题地存储在数据库中，但两种情况下的重定向都不起作用。

我正在使用：Express、Body-Parser、Mongoose、Passport、Passport-local 和 Passport-local-mongoose。

护照配置

app.use(require("express-session")({
secret: "This is a test app",
resave: false,
saveUninitialized: false
}));
app.use(passport.initialize());
app.use(passport.session());
passport.use(new LocalStrategy(User.authenticate()));
passport.serializeUser(User.serializeUser);
passport.deserializeUser(User.deserializeUser);

报名路线

app.post("/register", function(req, res) {
  var newUser = new User({username: req.body.username});
  User.register(newUser, req.body.password, function (err, user) {
    if (err) {
      console.log(err);
      return res.render("register");
    }
    passport.authenticate("local"),(req, res, function(){
      res.redirect("/campgrounds");
    });
  });
});

登录路径

app.post("/login", 
passport.authenticate("local", {
  successRedirect: "/campgrounds",
  failureRedirect: "/login"
}));

【解决方案1】：

将其写入您的护照配置中并尝试在您的应用程序中将变量名称与您的匹配

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

  // asynchronous
  process.nextTick(function() {

  //  Whether we're signing up or connecting an account, we'll need
  //  to know if the email address is in use.
  User.findOne({'username' :  usernameCB}, function(err, existingUser) {

      // if there are any errors, return the error
      if (err)
          return done(err);

      // check to see if there's already a user with that email
      if (existingUser)
          return done(null, false);

      //  If we're logged in, we're connecting a new account.
      if(req.user) {
        console.log(req.user);
          var user              = req.user;
          User.username    = usernameCB;
          User.password = user.generateHash(passwordCB);
          User.save(function(err) {
              if (err)
                  throw err;
              return done(null, user);
          });
      }
      //  We're not logged in, so we're creating a brand new user.
      else {
          // create the user
          var User            = new User();

          User.username    = usernameCB;
          User.password =   User.generateHash(passwordCB);

          User.save(function(err) {
              if (err)
                  throw err;
              return done(null, user);
          });
      }});
  });
}));

在你的路线中

    app.post('/signup',passport.authenticate('local-signup',{
      successRedirect:'/campgrounds',
      failureRedirect:'/login'
    }))
