语法:
const server.close()
参数:此方法不接受任何参数。
返回值:这个方法只返回一个监听服务器实例的回调函数。

示例 1: 文件名:index.js
// Node.js program to demonstrate the
// server.close() method
var tls = require('tls'),
fs = require('fs'),
// Port and host address for server
PORT = 1337,
HOST = '127.0.0.1';
// Private key and public certificate for access
var options = {
key: fs.readFileSync('private-key.pem'),
cert: fs.readFileSync('public-cert.pem'),
rejectUnauthorized: false
};
// Creating and initializing server
var server = tls.createServer(options, function(socket) {
// Print the data that we received
socket.on('data', function(data) {
console.log('\nReceived: %s ',
data.toString().replace(/(\n)/gm, ""));
});
// Stopping the server
// by using the close() method
server.close(()=>{
console.log("server closed successfully");
})
});
// Start listening on a specific port and address
server.listen(PORT, HOST, function() {
console.log("I'm listening at %s, on port %s", HOST, PORT);
});
// Creating and initializing client
var client = tls.connect(PORT, HOST, options, function() {
// Getting the bound address
// by using address method
const value = client.address();
client.write("Bound address : " + value);
client.end();
});
使用以下命令运行 index.js 文件:
node index.js
输出:
I'm listening at 127.0.0.1, on port 1337
Received: Bound address : [object Object]
server closed successfully
