Node.js http2.createServer()用法及代码示例


http2.createServer()是http2模块内的类http2的内置应用程序编程接口，用于创建net.Server对象。

用法:

http2.createServer(options[, onRequestHandler])

参数：此方法将以下参数作为参数：

  • options:根据需要，它可以是maxDeflateDynamicTableSize，maxSettings，maxSessionMemory等。
  • onRequestHandler:它是作为函数类型的参数传递的可选参数。

返回值：此方法返回net.Server的对象。

如何生成私钥和公共证书？



  1. 私钥：打开记事本并复制粘贴以下 key ：
    -----BEGIN RSA PRIVATE KEY-----
MIICXQIBAAKBgQC38R9wXcUbhOd44FavgmE5R3K4JeYOHLnI7dUq1B8/Gv7l3SOg
JKef/m9gM1KvUx951mapXGtcWgwB08J3vUE2YOZ4tWJArrVZES0BI/RmFAyhQFP5

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

    现在将文件另存为private-key.pem

  2. 公开证书：打开记事本并复制粘贴以下 key ：
    -----BEGIN CERTIFICATE-----
MIICfzCCAegCCQDxxeXw914Y2DANBgkqhkiG9w0BAQsFADCBgzELMAkGA1UEBhMC

-----END CERTIFICATE-----

    现在将文件另存为public-cert.pem

范例1： 文件名：index.js

// Node.js program to demonstrate the 
// http2.createServer() 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 '); 
    stream.end('world'); 
  
    // Stopping the server 
    // by using the close() method 
    server.close(() => { 
        console.log("server closed"); 
    }) 
}); 
  
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 closed"); 
    }) 
});

使用以下命令运行index.js文件：

node index.js

输出：

status:200
Received:hello
Received:world
client closed
server closed

范例2： 文件名：index.js

// Node.js program to demonstrate the 
// http2.createServer() 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.end('world'); 
  
    // Stopping the server 
    // by using the close() method 
    server.close(() => { 
        console.log("server closed"); 
    }) 
}); 
  
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 closed"); 
    }) 
});

使用以下命令运行index.js文件：

node index.js

输出：

Received:world
client closed
server closed
