Node.js readStream.isRaw用法及代碼示例

// Node.js program to demonstrate the 
// readStream.isRaw property 
  
// 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; 
  
    // 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");
