模块，如下所示：
https我已经针对Google的透明度报告中列出的一些不安全网站对此进行了测试：https://transparencyreport.google.com/https/top-sites
部分结果：
const https = require('https');
const options = {
host: 'www.some-site.com',
method: 'get',
path: '/'
};
const req = https.request(options, res => {
console.log('Certificate Status: ', res.socket.authorized);
});
req.on('error', error => {
console.error('Error: ', error);
});
req.end();
- aliexpress.com更正Certificate Status: true - expired.badssl.com更正两者都正确。但是，当网站完全不使用SSL时，Certificate Status: false的值仍为真：
socket.authorized - alibaba.com错误Certificate Status: true - www.bbc.com错误验证域是否具有有效SSL证书的正确方法是什么？
答案 0 :(得分：0)
正如我的问题评论中指出的那样，这些网站恰好在加载网站后立即使用从https到http的重定向。因此，最初的有效证书＆＃39;结果是正确的。
为了解决这个问题，我使用了npm包zfollow-redirects`，这解决了这个问题。
来自包装说明：
自动替换节点http和https 跟随重定向。
