Node.js和ExpressJS主体解析器包检索数据

Question

OK first time user of Node, and I am trying to send data to backend/index.js

Requirements

• Post data to back-end node
• Retrieve posted data and store values as variables

Whats the problem

The post is 200 success, that works.

however when I navigate to :

http://localhost:8080/backend/index

I get :

Cannot GET /backend/index

Where am I going wrong ?

Here is my front end post post

var settings = {
  "async": true,
  "crossDomain": true,
  "url": "http://localhost:8080/backend/index.js",
  "method": "POST",
  "headers": {
    "content-type": "application/x-www-form-urlencoded"
  },
  "data": {
    "id": "1223",
    "token": "223",
    "geo": "ee"
  }
}

$.ajax(settings).done(function (response) {
  console.log(response);
});

I am trying to retrieve this data from and store as variable in the back end node.

backend/index.js

// grab the packages we need
var express = require('express');
var app = express();
var port = process.env.PORT || 8080;

// routes will go here

// start the server
app.listen(port);
console.log('Server started! At http://localhost:' + port);

var bodyParser = require('body-parser');
app.use(bodyParser.json()); // support json encoded bodies
app.use(bodyParser.urlencoded({ extended: true })); // support encoded bodies

// POST http://localhost:8080/api/users
// parameters sent with
app.post('/backend/index', function(req, res) {
    var user_id = req.body.id;
    var token = req.body.token;
    var geo = req.body.geo;

    res.send(user_id + ' ' + token + ' ' + geo);
});

Answer 1

I think you didn't specify GET method, you can do like this

app.get('/', function(req, res) {
    res.send('do something 1');
});

app.get('/backend/index', function(req, res) {
    res.send('do something 2');
});

Hope this will help!

Answer 2

Because you Post Api and you can not get result without parameter. Your Post Api will not give output until you hit only url on web browser, so need postman for Post Api.

Now you get Output without any problem.

Thanks in Advance
