返回值:这个方法只返回一个回调函数做进一步操作。
示例 1:文件名:index.js
java 描述语言
// Node.js program to demonstrate the
// server.setTimeout() APi
// Importing http module
var http = require('http');
// Setting up PORT
const PORT = process.env.PORT || 3000;
// Creating http Server
var httpServer = http.createServer(
function(request, response){
// Getting the reference of the
// underlying socket object
// by using socket API
const value = response.socket;
// Display result
// by using end() api
response.end( "socket buffersize : "
+ value.bufferSize, 'utf8', () => {
console.log("Displaying the result...");
});
});
// Listening to http Server
// by using listen() api
httpServer.listen(PORT, () => {
console.log(
"Server is running at port 3000...");
});
httpServer.setTimeout(3000,()=>{
console.log(
"Socket is destroyed due to timeout")
// Closing server
// by using close() api
httpServer.close(()=>{
console.log("Server is closed")
})
})
使用以下命令运行 index.js 文件:
node index.js
控制台输出:
Server is running at port 3000...
Displaying the result...
Displaying the result...
Socket is destroyed due to timeout
Socket is destroyed due to timeout
Server is closed
Server is closed
浏览器输出:在浏览器的搜索栏中粘贴 localhost 地址 http://localhost:3000/即可。
socket buffersize : 0

// Display result
// by using end() api

+ value.localAddress, 'utf8', () => {
