原文:https://www . geesforgeks . org/node-js-http-server response-settimeout-method/
HTTP servereresponse . settimeout是 HTTP 模块中类 ServerResponse 的内置应用编程接口，用于将套接字的超时值设置为毫秒(毫秒)。
语法:
const response.setTimeout(msecs[, callback])
参数:该方法以毫秒为单位取第一个参数为套接字超时值，第二个参数为回调函数，可选。
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: Filename-index.js
java 描述语言
// Node.js program to demonstrate the
// response.setTimeout() method
// 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) {
// Setting the socket time out value
// by using setTimeout method
response.setTimeout(6000,() => {
console.log("socket is destroyed due to timeout")
})
});
// Listening to http Server
httpServer.listen(PORT, () => {
console.log("Server is running at port 3000...");
});
使用以下命令运行 index.js 文件:
node index.js
输出:
Server is running at port 3000...
socket is destroyed due to timeout
现在打开浏览器，转到http://localhost:3000/，会看到如下输出:
ERR_CONNECTION_REFUSED
示例 2:Filename-index . js
Javascript
// Node.js program to demonstrate the
// response.setTimeout() Method
// Importing http module
var http = require('http');
// Request and response handler
const httpHandlers = (request, response) => {
// Setting the socket time out value
// by using setTimeout method
response.setTimeout(5000,() => {
console.log("socket is destroyed due to timeout")
})
}
// Creating http Server
var httpServer = http.createServer(
httpHandlers).listen(3000, () => {
console.log("Server is running at port 3000...");
});
使用以下命令运行 index.js 文件:
node index.js
输出:
Server is running at port 3000...
socket is destroyed due to timeout
现在打开浏览器，转到http://localhost:3000/，会看到如下输出:
ERR_CONNECTION_REFUSED
