示例 1：文件名：index.js

Javascript

// Node.js program to demonstrate the
// Http2ServerRequest.complete method
 
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) => {
 
  // Checking if the request has been
  // completed, aborted, or destroyed.
  // by using request.complete method
  const auth = request.complete;
 
  if(auth)
    console.log("request has been completed,"
      + " aborted, or destroyed")
  else
    console.log("request has not been completed,"
      + " aborted, or destroyed")
};
 
// Creating and initializing server
// by using http2.createServer() method
const server = http2.createServer(
    options, http2Handlers);
 
server.on('stream', (stream, requestHeaders) => {
  stream.respond({
    ':status': 200,
    'content-type': 'text/plain'
  });
  stream.write('hello ');
 
  // Getting all information of this http2stream object
  // by using state method
  const status = stream.state;
 
  stream.end("priority weight : " + status.weight);
 
  // Stopping the server
  // by using the 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');
 
const req = client.request({
  ':method': 'GET', ':path': '/' });
 
req.on('response', (responseHeaders) => {
  console.log("status : "
  + responseHeaders[":status"]);
});
 
req.on('data', (data) => {
  console.log('Received: %s ',
  data.toString().replace(/(\n)/gm,""));
});
 
req.on('end', () => {
  client.close(() => {
    console.log("client destroyed");
  })
});

使用以下命令运行index.js文件：

node index.js

输出：

request has not been completed, aborted, or destroyed
status : 200
Received: hello
Received: priority weight : 16
client destroyed
server destroyed
