步骤 - 2:另存为public-cert.pem
范例1: 文件名:index.js
Javascript
// Node.js program to demonstrate the
// request.aborted property
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'),
};
// Creating and initializing server
// by using http2.createServer() method
const server = http2.createServer(options);
server.on('stream', (stream, requestHeaders) => {
stream.respond({
':status':200,
'content-type':'text/plain'
});
stream.write('hello ');
const http2session = stream.session;
// Getting state associated with this
// session by using state API
const status = http2session.state;
stream.end("local window size:"
+ status.localWindowSize);
// Stopping the server by
// using the close() method
server.close(()=>{
console.log("server localSettings");
})
});
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 localSettings");
})
const status = req.aborted;
if(status)
console.log("request is aborted")
else
console.log("request is not aborted");
});
输出:
status:200 Received:hello Received:local window size:65535 request is not aborted client localSettings server localSettings
使用以下命令运行index.js文件:
node index.js
范例2: 文件名:index.js
Javascript
// Node.js program to demonstrate the
// http2session.state property
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'),
};
// Creating and initializing server
// by using http2.createServer() method
const server = http2.createServer(options);
server.on('stream', (stream, requestHeaders) => {
// Getting session object
// by using session api
const http2session = stream.session;
// Getting state associated with this
// session by using state API
const status = http2session.state;
stream.end("numeric id of recent data:"
+ status.lastProcStreamID);
// 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('data', (data) => {
console.log('Received:%s ',
data.toString().replace(/(\n)/gm,""));
});
req.on('end', () => {
client.close(()=>{
console.log("client destroyed");
})
const status = req.aborted;
if(status)
console.log("request is aborted")
else
console.log("request is not aborted");
});
输出:
Received:numeric id of recent data:1 request is not aborted client destroyed server destroyed
