我不知道如何在注册表单中使用带有passport.js的快速验证器，以及哪些用户将数据保存在数据库中我发送这些文件以检查它并检查错误 当我在没有expressvalidator的情况下单独使用护照时，它总是会给我带来失败的重定向没有成功的重定向
``在这里输入代码`这是用户模型
var express = require('express');
var router = express.Router();
var User = require("../models/user");

});

"use strict";

});

"use strict";

});
router.get("/profile", function (req, res, next) {
"use strict";
res.render("user/profile");

router.post("/signup", function (req, res, next) {
