【问题描述】：
I am trying to send a TCP Request to a server via IP:PORT...
此代码适用于我：
var net = require('net'); var client = new net.Socket();
const port = 1337; const HOST = "192.168.1.101";
function connect() {
client.connect({ port: PORT, host: HOST });
client.on('data', (data) => {
console.log(data);
client.destroy();
});
client.on('close', function() {
console.log('Connection closed');
});
}
此代码挂起，无响应： （另请注意：我在 io.connect 中的 IP 之前输入“http://”以响应不将主机名返回为未定义（见下文））：
console.log(socket); //returns=> undefined://192.168.1.101:1337
//uri: 'undefined//192.168.1.101:730',
const io = require('socket.io-client');
const socket = io.connect('192.168.1.101:1337');//=undefined hostname; works, but hangs
//const socket = io.connect('http://192.168.1.101:1337'); //works, but hangs as well...
function connect() {
console.log('connecting...');
**socket.on('connect', () => {**
console.log('Successfully connected!');
// add handlers for socket events
}); //I never receive response from socket.on('connect', ()=> {...
无论我尝试发送一个套接字，我都没有得到响应...... 它只是挂起，等待响应...
任何帮助都将不胜感激！
console.log(socket); //this command returns the following response from command down below:
