Node.js tlsSocket.getPeerFinished() 方法

tlsSocket.getPeerFinished()方法是 tls 模块中 TLSSocket 类的内置应用程序编程接口，用于返回作为 SSL/TLS 握手的一部分发送到套接字的最新完成消息，如果没有完成消息，则返回未定义已经发送了。

句法：

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密钥：

将文件另存为private-key.pem
公共证书：打开记事本并复制粘贴以下密钥：

将文件另存为public-cert.pem

javascript

// 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 access
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 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
