Node.js http2session.destroy()方法

原文:https://www . geesforgeks . org/node-js-http2 session-destroy-method/

http2session.destroy() 是 http2 模块中类 http2session 的内置应用程序编程接口，用于销毁该特定会话。

语法:

const http2session.destroy([error][, code])

参数:该方法采用以下两个可选参数作为参数:

  • 错误:如果由于错误导致 Http2Session 被销毁，则为错误对象。

  • 代码:为 HTTP/2 错误代码，否则为 NO_ERROR 代码。

返回值:这个方法没有什么可返回的。 如何生成私钥和公钥证书？

  1. 私钥:打开记事本，如下图复制粘贴如下密钥:

示例 1:文件名:index.js

java 描述语言

// Node.js program to demonstrate the
// http2session.destroy() 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.respond({
      ':status': 200,
      'content-type': 'text/plain'
   });

   stream.write('hello ');

   // Getting session object
   // by using session method
   const http2session = stream.session;

   // Getting alpnProtocol of this session
   // by using alpnProtocol method
   const alpnProtocol = http2session.alpnProtocol;

   stream.end("session protocol : " + alpnProtocol);

   // If any error occur
   http2session.on('error', (code) => {
     console.log(code);
   })

   // Callback for close event
   http2session.on('close', () => {
     console.log("session is destroyed");
   })

   // Stopping the server
   // by using the close() method
   server.close(() => {
      console.log("server destroyed");
      http2session.destroy();
  })
});

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:

status : 200
Received: hello
Received: session protocol : h2c
client destroyed
server destroyed
session is destoryed

示例 2: 文件名:index.js

使用以下命令运行 index.js 文件:

node index.js

输出:

session is closed
server destroyed
