node.js - 在 Node.js 中使用 MongoDB 使用电子邮件或用户名登录

Question

我想知道是否有办法让用户同时使用用户名或电子邮件登录我搜索了很多次，但没有找到一种工作方法。我不知道如何做到这一点，请尽可能提供最简单的方法。这是我的用户架构的样子:

var mongoose = require("mongoose");
var passportLocalMongoose = require("passport-local-mongoose");

var UserSchema = new mongoose.Schema({
    fullname: String,
    username: { type : String , lowercase : true , unique: true ,  required: true, minlength: 3, maxlength: 10},
    email: String, 
    password: String,
    mobile: String,
    gender: String,
    profession: String,
    city: String,
    country: String,
    joining: {type: Date, default: Date.now}
});

UserSchema.plugin(passportLocalMongoose);

module.exports = mongoose.model("User", UserSchema);

附加信息:我正在使用 nodejs。非常感谢任何帮助。谢谢

 //the simple example of login// 
 router.post('/users/login', function(req, res) {
     var users = req.app;
     var email = req.body.email;
     var password = req.body.password;
     var username = req.body.username;
     var data;
     if (email.length > 0 && password.length > 0) {
         data = {
             email: email,
             password: password
         };
     }
     elseif(username.length > 0 && password.length > 0) {
         data = {
             username: username,
             password: password
         };
     } else {
         res.json({
             status: 0,
             message: err
         });
     }
     users.findOne(data, function(err, user) {
         if (err) {
             res.json({
                 status: 0,
                 message: err
             });
         }
         if (!user) {
             res.json({
                 status: 0,
                 msg: "not found"
             });
         }
         res.json({
             status: 1,
             id: user._id,
             message: " success"
         });
     })
 } else {
     res.json({
         status: 0,
         msg: "Invalid Fields"
     });
 }
 });

 //and if you have to create schema 

 var db_schema = new Schema({
     email: {
         type: String,
         required: true,
         unique: true
     },
     password: {
         type: String,
         required: true,
         unique: true
     },
 });
 // define this in your db.js
 var login_db = mongoose.model('your_db_name', db_schema);
 return function(req, res, next) {
     req.app = login_db;
     next();
 };
