示例 1:Filename:index . js
Javascript
// Node.js program to demonstrate the
// Http2ServerResponse.setTimeout() API
const http2 = require('http2');
const fs = require('fs');
// Private key and public certificate for access
const options = {
key: fs.readFileSync('private-key.pem'),
cert: fs.readFileSync('public-cert.pem'),
};
// Request and response handler
const http2Handlers = (request, response) => {
// Setting timeout for the stream
response.setTimeout(3000,()=>{
response.end("surprise!!!")
})
};
// Creating and Initializing server using
// http2.createServer() method
const server = http2.createServer(options, http2Handlers);
server.on('stream', (stream, requestHeaders) => {
// Stopping the server by using close method
server.close(()=>{
console.log("server destroyed");
})
});
server.listen(8000);
// Creating and initializing client by
// using tls.connect() method
const client = http2.connect('http://localhost:8000');
// Handling the request
const req = client.request({
':method': 'GET', ':path': '/' });
req.on('response', (responseHeaders) => {
// Showing the response
console.log("status : " + responseHeaders[":status"]);
});
req.on('data', (data) => {
// Showing the data
console.log('Received: %s ',
data.toString().replace(/(\n)/gm,""));
});
req.on('end', () => {
// Closing the client
client.close(()=>{
console.log("client destroyed");
})
});
使用以下命令运行 index.js 文件:
node index.js
输出:
status : 200
Received: surprise!!!
client destroyed
server destroyed
