如何生成私钥和公钥证书？
1。文件名:私钥
打开记事本，复制粘贴以下密钥，将文件保存为 私钥. PEMT0】
2。文件名:公共证书
打开记事本，复制粘贴以下密钥，将文件保存为 公共证书T0】
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

console.log("client destroyed");
})
});
使用以下命令运行 index.js 文件:
node index.js
输出:
Received: request has not been completed, aborted, or destroyed
client destroyed
server destroyed
