Node.js how to pass Ajax success message to app.js, because i need to know user Log-in status

Node.js如何将Ajax成功消息传递给app.js,因为我需要知道用户登录状态

ex:If user have not logged in, redirect to log-in.html, so I need to know success message.

例如:如果用户尚未登录,请重定向到log-in.html,因此我需要知道成功消息。

index.html

...
<script src="//code.jquery.com/jquery-1.11.3.min.js"></script>
<script type="text/javascript>

            $.ajax({
                url: URLs,
                data: $('#sentToBack').serialize(),
                type:"POST",
                dataType:'text',

                success: function(msg){
                   if(msg == "True")
                   {
                     location.href = '/index.html';
                   }

                },

                 error:function(msg){ 
                    console.log(msg);
                 }
            });

</script>

app.js

var express = require('express');
var app = express();

app.get('/', function(req, res){
  // I want to send to here !!
});

app.listen(3000);

There are many different ways to do this.

有很多不同的方法可以做到这一点。

This here

app.get('/', function(req, res){
  // I want to send to here !!
});

is defining the function that will handle get requests to your root route.

正在定义将处理对根路由的请求的函数。

If you are sending AJAX requests, you need to think about what METHOD (GET/POST/PUT/DELETE) you are using, and what CONTENT you are sending. You may need something to parse the body if you are, for example, using JSON.

如果您要发送AJAX请求,则需要考虑您正在使用的METHOD(GET / POST / PUT / DELETE)以及您要发送的内容。例如,如果您使用JSON,则可能需要一些东西来解析主体。

If you want to maintain session information and logins etc, I would suggest looking into some middleware like PassportJS.

如果你想维护会话信息和登录等,我建议你研究一些像PassportJS这样的中间件。

You can configure Passport to automatically redirect to the login page whenever a request is received from an unauthenticated user.

您可以将Passport配置为在收到未经身份验证的用户的请求时自动重定向到登录页面。
