检索时自签名 SSL 证书更改

Question

I have a very simple flask HTTPS server running using a self-signed certificate on a google compute instance.我有一个非常简单的 Flask HTTPS 服务器，它在 google 计算实例上使用自签名证书运行。 Here is the code for the server:这是服务器的代码：

from flask import Flask
app = Flask(__name__)

with open("test_certificate.pem",'r') as inputFile:
    print(inputFile.read())

if __name__=="__main__":
    app.run(ssl_context=("test_certificate.pem", "test_key.pem"), 
        debug=True, host="0.0.0.0", port=443)

When I start the server I receive the following output:当我启动服务器时，我收到以下输出：

I was having issues sending HTTPS requests (I was receiving SSL "bad handshake" errors), so I executed the following code to see what the certificate was that was being returned:我在发送 HTTPS 请求时遇到问题（我收到 SSL“握手错误”错误），所以我执行了以下代码以查看返回的证书是什么：

import ssl 

serverSSL = ssl.get_server_certificate(('20.42.490.329',443))
print(serverSSL)
with open(VERIFY_PATH, 'w') as outputFile:
    outputFile.write(serverSSL)

This code outputs the following:此代码输出以下内容：

Why do these certificates not match?为什么这些证书不匹配？ I am assuming this is why I am getting the bad handshake error.我假设这就是我收到错误握手错误的原因。 Any suggestions are much appreciated任何建议都非常感谢

Ok, so you are using invalid certificates, and the reason why the file changes every time is that you are corrupting it.好的，所以您使用的是无效证书，并且每次文件都更改的原因是您正在破坏它。

This is what I use to get a TRUSTED certificate that most browsers can use: https://certbot.eff.org/instructions .这是我用来获得大多数浏览器可以使用的受信任证书的方法： https://certbot.eff.org/instructions : https://certbot.eff.org/instructions 。 Comment and tell me if this works for you.评论并告诉我这是否适合您。

Tho, if you really want to test this, just use Tho，如果你真的想测试这个，只需使用

if __name__ == "__main__":
    app.run(ssl_context='adhoc')
