快递员req.body是空的

Question

我知道这已经被问了很多次了，但是我一直在四处寻找，仍然找不到我的问题的答案。

这是我的代码，我确保在定义路由之前使用并配置body解析器。我只是在用。带bodyParser的json（），因为现在我只测试了一个POST函数，但我甚至尝试了应用程序。使用（bodyParser.urlencoded（{extended:true}））；

var express = require('express'),
    bodyParser = require('body-parser'),
    app = express();

app.use(bodyParser.json());
app.set('port', (process.env.PORT || 5000));

app.listen(app.get('port'), function() {
    console.log("Node app is running at localhost:" + app.get('port'))
});

app.post('/itemSearch', function(req, res) {
    //var Keywords = req.body.Keywords;
    console.log("Yoooooo");
    console.log(req.headers);
    console.log(req.body);
    res.status(200).send("yay");
});

这是我收到的答复

Node app is running at localhost:5000
Yoooooo
{ host: 'localhost:5000',
  connection: 'keep-alive',
  'content-length': '146',
  'cache-control': 'no-cache',
  origin: 'chrome-extension://fhbjgbiflinjbdggehcddcbncdddomop',
  'content-type': 'multipart/form-data; boundary=----WebKitFormBoundarynJtRFnukjOQDaHgU',
  'user-agent': 'Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/45.0.2454.101 Safari/537.36',
  'postman-token': '984b101b-7780-5d6e-5a24-ad2c89b492fc',
  accept: '*/*',
  'accept-encoding': 'gzip, deflate',
  'accept-language': 'en-GB,en-US;q=0.8,en;q=0.6' }
{}

在这一点上，我真的非常感谢任何帮助。谢谢

Answer 1

试试这个

 // create application/json parser
    app.use(bodyParser.json());
    // parse various different custom JSON types as JSON
    app.use(bodyParser.json({ type: 'application/*+json' }));
    // parse some custom thing into a Buffer
    app.use(bodyParser.raw({ type: 'application/vnd.custom-type' }));
    // parse an HTML body into a string
    app.use(bodyParser.text({ type: 'text/html' }));
    // parse an text body into a string
    app.use(bodyParser.text({ type: 'text/plain' }));
    // create application/x-www-form-urlencoded parser
    app.use(bodyParser.urlencoded({ extended: false }));

AFAIK您需要使用Body解析器：https://github.com/expressjs/body-parser

bodyParser = require('body-parser').json();
app.post('/itemSearch', bodyParser, function(req, res) {
  //var Keywords = req.body.Keywords;
  console.log("Yoooooo");
  console.log(req.headers);
  console.log(req.body);
  res.status(200).send("yay");
});

然后尝试使用PostMan将正文设置为rajson：

{
  "test": "yay"
}
