示例 1:文件名-index.js
Javascript
// Node.js program to demonstrate the
// response.writeProcessing() 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) {
// Sending a HTTP/1.1 102 Processing message
// by using socket method
response.writeProcessing();
// Display result
// by using end() method
response.end("HTTP/1.1 102 Processing message"
+ " has been sent", 'utf8', () => {
console.log("displaying the result...");
httpServer.close(() => {
console.log("server is closed")
})
});
});
// Listening to http Server
httpServer.listen(PORT, () => {
console.log("Server is running at port 3000...");
});
Javascript
// Node.js program to demonstrate the
// response.writeProcessing() method
// Importing http module
var http = require('http');
// Request and response handler
const http2Handlers = (request, response) => {
// Sending a HTTP/1.1 102 Processing message
// by using socket method
response.writeProcessing();
// Display result
// by using end() method
response.end("HTTP/1.1 102 Processing message"
+ " has been sent", 'utf8', () => {
console.log("displaying the result...");
httpServer.close(() => {
console.log("server is closed")
})
});
};
// Creating http Server
var httpServer = http.createServer(
http2Handlers).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...
displaying the result...
server is closed
现在在浏览器中运行http://localhost:3000/ ,您将在屏幕上看到以下输出:
HTTP/1.1 102 Processing message has been sent
