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:Filename:index . js
Javascript
// Node.js program to demonstrate the
// Http2ServerResponse.statusMessage 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) => {
// Getting status code
// using response.statusMessage method
const value = response.statusMessage;
// Display the display
console.log("status message : " + value)
};
// Creating and initializing server
// by using http2.createServer() method
const server = http2.createServer(options, http2Handlers);
server.on('stream', (stream, requestheader) => {
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('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:
status message :
(node:656) UnsupportedWarning: Status message is
not supported by HTTP/2 (RFC7540 8.1.2.4)
Received: hello
Received: priority weight : 16
client destroyed
server destroyed
示例 2:Filename:index . js
Javascript
// Node.js program to demonstrate the
// Http2ServerResponse.statusMessage method
const http2 = require('http2');
const fs = require('fs');
const { RSA_NO_PADDING } = require('constants');
// Private key and public certificate for access
const options = {

cert: fs.readFileSync('public-cert.pem'),
};
// Request and response handler
const http2Handlers = (request, response) => {
// Getting status code
// using response.statusMessage method
const value = response.statusMessage;
// Display the display
response.end("status message : " + value)
};
// Creating and initializing server
// by using http2.createServer() method
const server = http2.createServer(options, http2Handlers);
server.on('stream', (stream, requestHeaders) => {
// Getting all information of this http2stream object
// by using state method
const status = stream.state;
stream.end("The sum weight of all Http2Stream : " +
status.sumDependencyWeight);
// Stopping the server

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': '/www.geeksforgeeks.org' });
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:
(node:8360) UnsupportedWarning: Status message is not supported
by HTTP/2 (RFC7540 8.1.2.4)
Received: status message :
