java 描述语言
// Node.js program to demonstrate the
// response.statusMessage 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){
response.writeHead(200, {
'Content-Length': Buffer.byteLength("GeeksforGeeks"),
'Content-Type': 'text/plain'
})
// Getting the statusMessage
// by using statusMessage API
const value = response.statusMessage;
// Display result
// by using end() api
response.end( "hello World", 'utf8', () => {
console.log("displaying the result...");
httpServer.close(()=>{
console.log("server is closed")
})
});
console.log("status message : " + value)
});
// 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
控制台输出:
Server is running at port 3000...
status message : OK
displaying the result...
server is closed
示例 2:Filename:index . js
Javascript
// Node.js program to demonstrate the
// response.statusMessage APi

'Content-Type': 'text/plain'
}).end( "hello World", 'utf8', () => {

})
console.log("status message : " + value)
};
// Creating http Server
var httpServer = http.createServer(
http2Handlers).listen(3000, () => {
console.log("Server is running at port 3000...");
