使用 Superagent 和 Express 4 接收 POST 请求数据

Receiving POST request data using Superagent and Express 4

Express -v : 4.13.3

超级代理-v:1.4

从我的应用程序前端发送 POST 请求的函数:

search: () => {
    request.post('/api/search')
      .set('Content-Type', 'application/json')
      .send({hello: 'hello w'})
      .end((err, response) => {
        if (err) return console.error(err);

        serveractions.receiveTest(response);
      });
  }

我的 Express 路由器文件:

var express = require('express');
var router = express.Router();
var bodyParser = require('body-parser');

router.use(bodyParser.urlencoded({extended: false}));

router.post('/api/search', (req, res, next) => {
  console.log(req.body);
  res.json({test: 'post received'});
});

module.exports = router;

路由器已成功发送和接收请求,但 req.body 始终为空,即使我正在使用 Superagent .send({hello: 'hello w'})。我需要更改什么才能正确发送 json 对象并在我的路由器中接收它?

我找到答案了:

我将路由器文件更改为:

var express = require('express');
var router = express.Router();
var bodyParser = require('body-parser');

router.use( bodyParser.json() );
router.use(bodyParser.urlencoded({
  extended: true
}));

router.post('/api/search', (req, res, next) => {
  console.log(req.body);
  res.json({test: 'post received'});
});

module.exports = router;

我的请求方式为:

searchRequest : (data) => {
  request
    .post('/api/search')
    .send({ searchTerm : data })
    .end((err, res) => {
      if (err) console.log(err);
      console.log(res);
    })
}
