from pyngrok import ngrok
public_url = ngrok.connect(5000).public_url

我从 twilio 的文档中获取了这 2 行代码，用于自动化 ngrok 连接。基本上我只是想建立一个连接，然后将 web url 用作 webhook。但我的日志一直给我这个错误：

它适用于我同事的计算机，但不适用于我的计算机。我不确定错误是什么

当您使用某些代理或 VPN 时，这可以在 Python 中出现。但是，您可以轻松解决此问题，因为install_ngrok()需要kwargs传递到urlopen，如此处所述。

有无数种方法可以解决这个问题，因为它并不特定于任何一个 Python 包，但如果绕过 SSL 验证对您的应用程序来说是可接受的安全风险，那么这里有一个这样做的示例pyngrok（也在本期中突出显示）：

import ssl
from pyngrok import ngrok, conf, installer

pyngrok_config = conf.get_default()

if not os.path.exists(pyngrok_config.ngrok_path):
    myssl = ssl.create_default_context();
    myssl.check_hostname=False
    myssl.verify_mode=ssl.CERT_NONE
    installer.install_ngrok(pyngrok_config.ngrok_path, context=context)

public_url = ngrok.connect(5000).public_url

您应该更改：installer.install_ngrok(pyngrok_config.ngrok_path, context=context) 为 installer.install_ngrok(pyngrok_config.ngrok_path, context=myssl)
