現在將另存為public-cert.pem
示例1:Filename:index.js
// Node.js program to demonstrate the
// Http2Stream.sentInfoHeaders 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'),
};
// Creating and initializing server
// by using http2.createServer() method
const server = http2.createServer(options);
server.on('stream', (stream, requestHeaders) => {
stream.additionalHeaders({
':status':100,
'content-type':'text/plain'
});
// Getting rst stream code
// by using sentInfoHeaders api
const status = stream.sentInfoHeaders;
console.log(status)
stream.end("the end");
// 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");
})
});
使用以下命令運行index.js文件:
node index.js
輸出:
[ [Object:null prototype] { ':status':100, 'content-type':'text/plain' } ] Received:the end client destroyed server destroyed
範例2: 文件名:index.js
// Node.js program to demonstrate the
// Http2Stream.sentInfoHeaders 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'),
};
// Creating and initializing server
// by using http2.createServer() method
const server = http2.createServer(options);
server.on('stream', (stream, requestHeaders) => {
// Getting rst stream code
// by using sentInfoHeaders api
const status = stream.sentInfoHeaders;
stream.end("header object:" + status);
// Stopping the server
// by using the close() method
server.close(() => {
console.log("server destroyed");
})
});
server.listen(8000);
// Creating and intializing 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");
})
});
使用以下命令運行index.js文件:
node index.js
輸出:
Received:header object:undefined client destroyed server destroyed
