node.js - 捕获对等证书以供以后使用

问题描述

我正在尝试捕获连接的对等证书，以便以后可以在我的代码中使用这些证书。

'use strict';

const tls = require('tls');

console.log('Hello World!');
var certs = {};
const socket = tls.connect(
  { host: '192.168.1.23', port: 8080, rejectUnauthorized: false },
  () => {
    certs = socket.getPeerCertificate();
  },
);

console.log('Outside');
console.log(JSON.stringify(certs));
console.log('Good Bye World');

预期输出为

Hello World!

解决方案

我看到的问题是，tls.connect() 是一个异步函数，它会在一段时间后返回值，在此之前您尝试打印它并获取 {}。

在这种情况下，您可以使用事件。检查下面的代码，它工作正常并正确打印事件的预期内容。

 'use strict';

const tls = require('tls');
var events = require('events');
var eventEmitter = new events.EventEmitter();
var certs = {};
//Create an event handler:
var myEventHandler = function () {
    console.log('On Event');
    console.log(JSON.stringify(certs));
    console.log('Good Bye World');
  }
eventEmitter.on('GotTheCert', myEventHandler);

console.log('Hello World!');

const socket = tls.connect(
  { host: 'smtp-relay.gmail.com',port:465,  rejectUnauthorized: true },
  () => {
    

    certs = socket.getPeerCertificate();
    console.log('Inside ');
    console.log(JSON.stringify(certs));
    
  
    eventEmitter.emit('GotTheCert');


  },
);
