Javascript Nodejs post未访问文件所在的目录

我来自php背景，现在正在学习Nodejs。几个小时以来，我一直试图将电子邮件和短信从dashboard.html发送到服务器端user.js，但出现了错误

 Cannot POST /email
Cannot POST /sms

短信和电子邮件表单post似乎无法找到文件user.js

下面是目录结构

短信息和电子邮件表单都在dashboard.html中

转换

/routes/users.js

文件以正确生成和导出路由：

const express = require('express');

const router = express.Router();

router.post('/email', function(req, res){
    var post  = req.body;
    var title= post.subject;
    var mess= post.message;

    console.log(title);
    console.log(mess);

    ...
    // do your logic
    ...

    res.json(response); // being response the info you want to return, commonly an object    
});


router.post('/sms', function(req, res){
    var post  = req.body;
    var sms_message= post.sms_m;

    ...
    // do your logic
    ...

    res.json(response); // being response the info you want to return, commonly an object    
}

module.exports = router;

然后，您可以在执行以下操作时导入它们：

  var user = require('./routes/user');
  ...
  //And you will use them thus:
  app.use('/', user);

“短信和电子邮件表单post似乎无法找到user.js文件”-如果这是问题所在，那么当您试图请求该文件时，程序将抛出异常。您需要提供一个。我的代码没有任何错误。问题在于将电子邮件或sms表单从位于view目录内的dasboard.html发布到位于route目录内的user.js。表单上写着Cannot POST/email Cannot POST/sm我的意思是，既然没有出现错误，问题不在于找不到文件。您仍然需要提供一个。如果你不向我们展示如何将函数连接到服务器上，那么向我们展示你是如何创建几个可以用作路由的函数是不好的。这涉及到etcI在屏幕截图上显示的路由
