Question

我正在将json从Java应用程序发送到节点js服务器，但是在服务器中，它仅显示密钥而不显示json的值。我得到正确的响应，但解析不正确。这是我将json发送到节点服务器和服务器代码时的Java代码

EXISTS

这是服务器代码

httpURLConnection = (HttpURLConnection) url.openConnection();
         httpURLConnection.setReadTimeout(10000);
         httpURLConnection.setRequestMethod("POST");
         httpURLConnection.setConnectTimeout(15000);
         httpURLConnection.setDoInput(true);
         httpURLConnection.setDoOutput(true);
         httpURLConnection.setInstanceFollowRedirects(false);
            httpURLConnection.connect();
            OutputStreamWriter writer=new OutputStreamWriter(httpURLConnection.getOutputStream(),"UTF-8");
            JSONObject student1 = new JSONObject();
           JSONObject map = new JSONObject();
           map.put("name", "abc");
            writer.write(map.toString());
            System.out.println(map.toString());
            writer.close();

当我在Java中打印map.toString（）时，它会显示正确的json

var express=require('express');
var app=express();
var mysql=require('mysql');
var bodyParser=require('body-parser');
var urlencodedParser = bodyParser.urlencoded({ extended: false });
app.use(bodyParser.json());
app.post('/',urlencodedParser,function(req,res)
{
res.setHeader('Content-Type', 'application/json');
console.log(req.body);

res.end(JSON.stringify({ a: '1' }));
});
app.listen(8080,'127.0.0.1');
console.log('Now listening to port 8080');

，但在服务器中显示为

 {"name","abc"}

如果有人找到解决方案，请回复!!

map.put("name", "abc");
JSONObject jsonObject = new JSONObject(map);
System.out.println(jsonObject);

Answer 2

发现错误添加

httpURLConnection.setRequestProperty("Content-Type", "application/json; 
charset=UTF-8");

从Java应用程序发送时在服务器中未获得正确的json
