Node.js http2stream.id 方法

http2stream.id是 http2 模块中 Http2Stream 类的内置应用程序接口,用于返回该 Http2Stream 的数字流标识符。

句法:

const http2stream.id

参数:此方法不接受任何参数。

返回值:此方法返回此 Http2Stream 的数字流标识符。

如何生成私钥和公钥证书?

  1. 私钥:打开记事本并复制粘贴以下密钥:
    -----BEGIN RSA PRIVATE KEY-----
    MIICXQIBAAKBgQC38R9wXcUbhOd44FavgmE5R3K4JeYOHLnI7dUq1B8/Gv7l3SOg

    nUG9lYvH7DztWDTioXMrruPF7bdXfZOVJD8t0I4OUzvC
    -----END RSA PRIVATE KEY-----
    

    现在将文件保存为private-key.pem

  2. 公共证书:打开记事本并复制粘贴以下密钥:
    -----BEGIN CERTIFICATE-----
    MIICfzCCAegCCQDxxeXw914Y2DANBgkqhkiG9w0BAQsFADCBgzELMAkGA1UEBhMC

    hWF6W2H9+MAlU7yvtmCQQuZmfQ==
    -----END CERTIFICATE-----
    

    现在将文件保存为public-cert.pem

示例 1:文件名:index.js

// Node.js program to demonstrate the
// Http2Stream.id 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 stream identifier
   // by using id method
   const status = stream.id;
  
   stream.end("stream identifier : " + status);
  
   // 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:

status : 200
Received: hello
Received: stream identifier : 1
client destroyed
server destroyed

示例 2:文件名:index.js

// Node.js program to demonstrate the
// Http2Stream.id 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 stream identifier
   // by using id method
   const status = stream.id;
  
   stream.end("stream identifier : " + status);
    
   // 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:

Received: stream identifier : 1
client destroyed
server destroyed
