问使用Node js的基于Rest API的TCP客户端

EN

var Net = require('net');
var express = require("express");
var bodyParser = require('body-parser');
var app = express();

app.use(bodyParser.json());

app.post('/api/push', function (req, res) {

var reqBody = req.body.reqBody;

var req = JSON.stringify(reqBody);

const client = new Net.Socket({
        allowHalfOpen: true
    });

client.connect({
    port: req.body.port,
    host: req.body.host
}, function () {

    client.write(req);

});

client.on('data', function (chunk) {

    res.write(chunk.toString());

    //Tried to use client connection information, but didnt worked not sure if i missed something.
    console.log(JSON.stringify(client));

    // Tried commenting below client.end but no luck.
    client.end();

});

client.on('end', function () {
    res.end();

});

client.on('error', function (err) {

    console.log("Error: " + err.message);
    res.write(err.message);
    client.end();

});

});

app.listen(1234, () => {
    console.log("Server running on port 1234");
});
