Node.js tlsSocket.getPeerFinished()用法及代码示例

tlsSocket.getPeerFinished()方法是tls模块内TLSSocket类的内置应用程序编程接口，用于返回已作为SSL /TLS握手的一部分发送到套接字的最新的Finished消息，如果尚未完成，则未定义已发送。

用法:

const tlsSocket.getPeerFinished()

参数：此方法不接受任何参数。

返回值：此方法返回一个缓冲区对象，其中包含完整握手的消息摘要。

如何生成私钥和公共证书？

私钥：打开记事本并复制粘贴以下 key ：

将文件另存为private-key.pem

公开证书：打开记事本并复制粘贴以下 key ：

将文件另存为public-cert.pem

范例1： 文件名：index.js

// Node.js program to demonstrate the 
// tlsSocket.getPeerFinished() method 
  
var tls = require('tls'), 
    fs = require('fs'), 
  
    // Port and host address for server     
    PORT = 1337, 
    HOST = '127.0.0.1', 
    value = null; 
  
// Private key and public  
// certificate for acess 
var options = { 
    key:fs.readFileSync('private-key.pem'), 
    cert:fs.readFileSync('public-cert.pem'), 
    rejectUnauthorized:false
}; 
  
// Creating and initializing server 
var server = tls.createServer(options,  
                    function (socket) { 
  
    // Print the data that we received 
    socket.on('data', function (data) { 
        console.log('\nReceived:%s ', 
            data.toString().replace(/(\n)/gm, "")); 
    }); 
  
    // Stopping the server 
    // by using the close() method 
    server.close(() => { 
        console.log("Server closed successfully"); 
    }); 
}); 
  
  
// Start listening on a specific port 
// and address by using listen() method 
server.listen(PORT, HOST, function () { 
    console.log("I'm listening at %s, "
        + "on port %s", HOST, PORT); 
}); 
  
// Creating and initializing client 
var client = tls.connect(PORT, HOST,  
                options, function () { 
  
    // Getting finished message digest 
    // by using tlsSocket.getPeerFinished() 
    // method 
    value = client.getPeerFinished(); 
  
    client.write("Finisher message:" 
            + value.toJSON().data); 
  
    client.end(() => { 
        console.log("Client closed successfully"); 
    }); 
});

输出：

I’m listening at 127.0.0.1, on port 1337
Client closed succefully

Received:Finisher message:133, 120, 218, 179, 42, 34, 167, 40, 96, 3, 66, 211, 61, 190, 255, 206, 180, 162, 245, 65, 237, 69, 57, 234, 179, 148, 65, 62, 113, 30, 160, 106, 134, 175, 176, 198, 52, 25, 248, 25, 76, 129, 167, 159, 166, 241, 2, 97
Server closed successfully

范例2： 文件名：index.js

// Node.js program to demonstrate the 
// tlsSocket.getPeerFinished() method 
  
var tls = require('tls'), 
    fs = require('fs'), 
  
    // Port and host address for server     
    PORT = 1337,

}; 
  
// Creating and initializing server 
var server = tls.createServer(options,  
                function (socket) {

    value = socket.getPeerFinished(); 
  
    socket.write("Finisher message:" 
            + value.toJSON().data); 
  
    // Stopping the server 
    // by using the close() method 
    server.close(() => { 
        console.log( 
        "Server closed successfully") 
    }); 
}); 
  
// Start listening on a specific  
// port and address by using  
// listen() method 
server.listen(PORT, HOST, function () { 
    console.log("I'm listening at %s, "
        + "on port %s", HOST, PORT); 
}); 
  
// Creating and initializing client 
var client = tls.connect(PORT, HOST,  
            options, function () { 
    console.log("client is connected"); 
}); 
  
client.on("data", function (data) { 
  
    console.log('Received:%s', 
        data.toString().replace(/(\n)/gm, "")); 
  
    // Close the connection after  
    // receiving the message 
    client.end(() => { 
        console.log("client closed successfully") 
    }); 
});

使用以下命令运行index.js文件：

node index.js

输出：

I’m listening at 127.0.0.1, on port 1337
client is connected
Received:Finisher message:114, 99, 193, 23, 71, 139, 48, 221, 208, 160, 177, 63, 186, 157, 188, 76, 188, 83, 85, 24, 2, 10, 53, 8, 21, 150, 189, 35, 162, 118, 153, 232, 246, 60, 18, 225, 24, 29, 4, 113, 16, 126, 156, 69, 105, 16, 24, 151
client closed successfully
Server closed successfully
