快速路由在json中调用意外令牌

Question

我需要帮助我在Express中使用路由并进行后期调用，并在postrequest中检索数据。

我尝试通过登录req.body来检索数据，但是返回{}，我尝试将bodyParser添加到我的App.js中，当我拨打电话时会出现以下错误：

  

POST http://localhost:3000/enquete/test/ 400（错误请求）

SyntaxError: Unexpected token # in JSON at position 0

这是我的代码：

App.js

const express = require('express')
const app = express()
var MongoClient = require('mongodb').MongoClient
  , co = require('co')
  , assert = require('assert')
  , bodyParser = require('body-parser');
var indexRouter = require('./routes/index.js');
var enqueteRouter = require('./routes/enquete.js');

// support parsing of application/json type post data
app.use(bodyParser.json());

//support parsing of application/x-www-form-urlencoded post data
app.use(bodyParser.urlencoded({ extended: true }));

app.set('view engine', 'pug');
app.use('/', indexRouter);
app.use('/enquete', enqueteRouter);
app.use(express.static(__dirname + '/routes'));
app.use(express.static(__dirname + '/public'));

app.listen(3000, () => console.log('Example app listening on port 3000!'))

路由/ enquete.js

const express = require('express')
var router = express.Router()

router.post('/test/', function(req,res,next){
  console.log('request:',req.body);
  res.send('hello');
})
module.exports = router;

调用Ajax

function save(array){
    $.ajax({
        type: 'POST',
        data: { name: "Test", location: "TestUSA" },
        contentType: 'application/json',
                url: 'http://localhost:3000/enquete/test/',
                success: function(data) {
                        console.log('success');
                        console.log(JSON.stringify(data));
                },
                error: function(error) {
                        console.log('error:', error)
                 }
        });
}

您可以使用Postman来测试路线吗？由于您使用x-www-form-urlencoded

，请务必选择bodyparser.urlencoded({ extended: true })作为正文格式
