http.ClientRequest.setNoDelay()是HTTP模块内ClientRequest类的内置应用程序编程接口,该接口用于设置套接字,例如在不需要限制请求时延迟过多的请求。
用法:
const request.setNoDelay([noDelay])
参数:此方法将布尔值作为参数。
返回值:此方法无返回值。
范例1:Filename-index.js
Javascript
// Node.js program to demonstrate the
// request.setNoDelay() method
// Importing http module
const http = require('http');
// Create an HTTP server
const server = http.createServer((req, res) => {
res.writeHead(200, { 'Content-Type':'text/plain' });
res.end('okay');
});
// Now that server is running
server.listen(3000, '127.0.0.1', () => {
// Make a request
const options = {
port:3000,
host:'127.0.0.1',
headers:{
'Connection':'Upgrade',
'Upgrade':'websocket'
}
};
// Getting clinet request
const req = http.request(options);
req.host = '127.0.0.1'
// Setting the nodelay for the socket
// by using setNoDelay method
req.setNoDelay(true);
// Display the result
console.log("no delay is set")
process.exit(0)
});
使用以下命令运行index.js文件:
node index.js
输出:
no delay is set
示例2:Filename-index.js
Javascript
// Node.js program to demonstrate the
// request.setNoDelay() method
// Importing http module
const http = require('http');
// Create an HTTP server
http.createServer((req, res) => {}).listen(3000, '127.0.0.1', () => {
// Getting clinet request
const req = http.request({
port:3000,
host:'127.0.0.1',
});
// Setting the nodelay for the socket
// by using setNoDelay method
req.setNoDelay(true);
// Display the result
console.log("no delay is set")
process.exit(0)
});
使用以下命令运行index.js文件:
node index.js
输出:
no delay is set
