如何生成私钥和公共证书？

1.FileName：私钥

第 1 步：打开记事本并复制粘贴以下密钥并将文件保存为private-key.pem

-----BEGIN RSA PRIVATE KEY-----

2.FileName：公共证书

步骤 - 1 ：打开记事本并复制粘贴以下密钥并将其另存为public-cert.pem

示例 1：文件名：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
