node.js express.js发布数据

我在获取客户端POST数据时遇到如下问题：

http.createServer(function onRequest(request, response) {               
    request.setEncoding("utf8");
    var content = [];

    request.addListener("data", function(data) {
        content.push(data); //Collect the incoming data});

    //At the end of request call
    request.addListener("end", function() {
    response.writeHead( 200, {"Content-Type": "text/plain"} );
    ms = content[0];
    if(ms.toString() != "")
    {
        var msg = ms.toString();    //Parse the ms into string      
        console.log(msg); // Prints the message in the console
        var reqObj = JSON.parse(msg);   // If the incoming message is in JSON format, it can be parsed as JSON.
        console.log(reqObj); 
        response.end(); //Close the response
    }
});

{ "{\"account\": \"123456\"}": "" }
undefined

我的客户发送了：

content-type:application/x-www-form-urlencoded

内容：

{"value":"123456"}

在node.js中，将内容解析为json对象没有问题，我的代码如下：

http.createServer(function onRequest(request, response) {               
    request.setEncoding("utf8");
    var content = [];

    request.addListener("data", function(data) {
        content.push(data); //Collect the incoming data});

    //At the end of request call
    request.addListener("end", function() {
    response.writeHead( 200, {"Content-Type": "text/plain"} );
    ms = content[0];
    if(ms.toString() != "")
    {
        var msg = ms.toString();    //Parse the ms into string      
        console.log(msg); // Prints the message in the console
        var reqObj = JSON.parse(msg);   // If the incoming message is in JSON format, it can be parsed as JSON.
        console.log(reqObj); 
        response.end(); //Close the response
    }
});

{ "{\"account\": \"123456\"}": "" }
undefined

上述代码的输出： {“account”：“48264”}//解析为JSON之前 {account:'48264'}//解析为JSON后

但当我改成express.js并使用bodyParser时，它就错了

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

/* GET users listing. */
router.post('/', function(req, res, next) {
    req.setEncoding('utf8');
    console.log(req.body);
    console.log(req.body.value);
});
module.exports = router;

控制台中的上述输出如下所示：

http.createServer(function onRequest(request, response) {               
    request.setEncoding("utf8");
    var content = [];

    request.addListener("data", function(data) {
        content.push(data); //Collect the incoming data});

    //At the end of request call
    request.addListener("end", function() {
    response.writeHead( 200, {"Content-Type": "text/plain"} );
    ms = content[0];
    if(ms.toString() != "")
    {
        var msg = ms.toString();    //Parse the ms into string      
        console.log(msg); // Prints the message in the console
        var reqObj = JSON.parse(msg);   // If the incoming message is in JSON format, it can be parsed as JSON.
        console.log(reqObj); 
        response.end(); //Close the response
    }
});

{ "{\"account\": \"123456\"}": "" }
undefined

我在网上搜索了一下，但找不到答案。请帮忙。

提前感谢

在定义任何路由之前，您需要使用express body解析器中间件

var bodyParser = require('body-parser');
var app = express();
port = parseInt(process.env.PORT, 10) || 8080;

// parse application/x-www-form-urlencoded
app.use(bodyParser.urlencoded({ extended: true }));

// parse application/json
app.use(bodyParser.json());

app.listen(port);

app.post("/someRoute", function(req, res) {
  console.log(req.body);
  res.status(200).json({ status: 'SUCCESS' });
});

代码输出中有一个错误，应该是：{“value”：“48264”}我还在app.js app.use（bodyParser.json（））中设置了bodyParser；use（bodyParser.urlencoded（{extended:true}））；你应该编辑你的问题，而不是评论你的更正。谢谢Kunal，我会尝试反馈Kunal，我检查过了，我已经在我的app.js中包含了你的代码。但还是不适合我。我会设法弄清楚会发生什么。谢谢。
