节点 js 发布 request.body undefined

Question

服务器.js

var express = require('express');
var app = express();
var bodyParser = require('body-parser');
var session = require('express-session');
var fs = require('fs');
var router = require('./router/main')(app, fs);

var server = app.listen(3000, function(){
  console.log('Express server has started on port 3000');
});

app.use(bodyParser.json());
app.use(bodyParser.urlencoded());

路由器/main.js

module.exports = function(app, fs)
{
  app.post('/addUser/', function(req, res){
        console.log(req.body);
    });
}

我使用 postman 工具：，请求参数 {"password": "pass","name" : "dltlsdn"}

但是... req.body 未定义... 为什么...？？

重新排序app.use语句。 早些时候，您在通过正文解析器之前处理请求。

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

//body parser before routes
app.use(bodyParser.json());
app.use(bodyParser.urlencoded());

var router = require('./router/main')(app, fs);

var server = app.listen(3000, function(){
   console.log('Express server has started on port 3000');
});

希望对您有所帮助。
