Node.js readStream.setRawMode()用法及代碼示例

// 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"); 
  
// Cathing the message event 
server.on("message", function (msg) { 
  
    // Creating and intializing 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");
