我有一个使用 http 运行良好的简单代码（不安全），但随后我将其更新为 https 出现错误ssl.SSLCertVerificationError

我正在使用具有有效 ssl 的 heroku 服务器，当然，mac 上的 python 3.7.3，ssl.OPENSSL_VERSION= 1.1.0，certifi=2019.3.9，Flask=1.0.2，Flask-SocketIO=3.3.2

这是代码：

import socketio

sio = socketio.Client()

@sio.on('connect')
def on_connect():
    print('Connected ...')

@sio.on('message')
def on_message(data):
    print('I received a message!')
    print(data)

if __name__ == '__main__':
    sio.connect('https://heroku.server.url')

这就是我使用 https 得到的：

Traceback (most recent call last):

    self._sslobj.do_handshake()
ssl.SSLCertVerificationError: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1056)

有任何想法吗 ？

最后我让它工作了，我在另一台具有相同软件条件的 Mac 计算机上尝试了相同的代码，它工作正常，也在 aPC with Ubuntu和 a上Raspberry Pi with Raspbian，一切正常，所以再次回到有问题的第一台 Mac 上，我开始调试再次，重新安装和更新软件包，pip但什么也没发生。

我尝试过的其他解决方案是重新安装certifi软件包，pip但没有得到任何修复。

最后，解决问题的方法是运行 Python 附带的位于 中的脚本/Applications/Python 3.X/Install Certificates.command，您可以直接Finder在其上双击运行它，也可以在终端上转到该文件夹​​并执行它。

完成此操作后，我进行了测试python-socketio 3.1.2，python-socketio 4.0.1一切正常。

最后的建议，如果您在尝试运行脚本后仍然遇到相同的错误，您可以尝试一个替代python-socketio方法socketIO-client-2初始条件（在运行脚本之前）。运行上面的脚本后，现在都运行完美了。
