示例 1: 文件名:index.js
java 描述语言
// Node.js program to demonstrate the
// readStream.setRawMode() method
// Importing dgram module
var dgram = require('dgram');
// Creating and initializing client
// and server socket
var client = dgram.createSocket("udp4");
var server = dgram.createSocket("udp4");
// Catching the message event
server.on("message", function (msg) {
// Creating and initializing a
// ReadStream object
let ReadStream = process.stdin;
// Setting the read stream Raw mode
// by using setRawMode() method
ReadStream.setRawMode(false);
// Checking if it is configured or not
// by using isRaw() method
const status = ReadStream.isRaw;
// Displaying the result
if (status)
process.stdout.write(msg + "configured" + "\n");
else
process.stdout.write(msg + "not configured" + "\n");
// Exiting process
process.exit();
})
// Binding server with port
.bind(1234, () => {
});
// Client sending message to server
client.send("It is ", 0, 7, 1234, "localhost");
输出:
It is not configured
