原文:https://www . geesforgeks . org/node-js-tlssocket-getpeerffinished-method/

tlsSocket . GetPeerFinished()方法是 TLS 模块内 tlsSocket 类的内置应用程序编程接口，用于返回作为 SSL/TLS 握手的一部分发送到套接字的最新已完成消息，如果尚未发送已完成消息，则返回未定义的消息。

语法:

const tlsSocket.getPeerFinished()

参数:此方法不接受任何参数。

返回值:这个方法返回一个包含完整握手消息摘要的缓冲区对象。

示例 1: 文件名:index.js

java 描述语言

// 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:

    // Close the connection after

});

使用以下命令运行 index.js 文件:

node index.js

输出:
