Node.js http2session.socket用法及代碼示例

http2session.socket是http2模塊內的類http2session的內置應用程序編程接口，用於返回充當net.Socket的Proxy對象。

用法:

const http2session.socket

參數：此方法不接受任何參數。

返回值：此方法返回充當net.Socket的Proxy對象。

如何生成私鑰和公共證書？

私鑰：打開記事本並複製粘貼以下 key ：

現在將文件另存為private-key.pem

公開證書：打開記事本並複製粘貼以下 key ：

現在將文件另存為public-cert.pem

範例1： 文件名：index.js

// Node.js program to demonstrate the 
// http2session.socket 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 '); 
  
   const http2session = stream.session; 
  
   // Getting socket associated with this session 
   // by using socket method 
   const status = http2session.socket; 
  
   stream.end("address family of socket:" 
      + status.address().family); 
  
   // Stopping the server 
   // by using the close() method 
   server.close(() => { 
     console.log("server localSettings"); 
  }) 
}); 
  
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 localSettings"); 
  }) 
});

使用以下命令運行index.js文件：

node index.js

輸出：

status:200
Received:hello
Received:address family of socket:IPv6
client localSettings
server localSettings

範例2： 文件名：index.js

// Node.js program to demonstrate the 
// http2session.socket 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 session object 
   // by using session method 
   const http2session = stream.session; 
  
   // Getting socket associated with this session 
   // by using socket method 
   const status = http2session.socket; 
  
   stream.end("port address of socket:" 
      + status.address().port); 
  
   // 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"); 
  })  
});

使用以下命令運行index.js文件：

node index.js

輸出：

Received:port address of socket:8000
client destroyed
server destroyed
