我可以获取flask_ngrok或py-ngrok生成的IP地址或域名并将其返回到

Question

我正在尝试获取部署后 Flask_ngrok 或 py-ngrok 生成的域名或 IP 地址。我想将flask_app部署到本地主机并在主页上获取新的IP地址或域名。

IE：如果我访问127.0.0.1/我希望它返回类似的内容 You can now log in through https://aaf8447ee878.ngrok.io/

我尝试检查目录并阅读一些帮助，但我仍然无法得到它。预先感谢❤

我发现最简单的方法是在用户访问该网站时复制网址。你可以通过...来做到这一点@app.before_requestdef before_request():    global url    url = request.url    # url = url.replace('http://', 'https://', 1)    url = url.split('.ngrok.io')[0]    url += '.ngrok.io'

你不需要那个global tunnel_urldef ngrok_url():    while True:        try:            print(ngrok_address)        except Exception as e:                print(e)您也可以在导入集之后 删除name == ' main '之前的线程部分ngrok_address = '' ，然后您可以在代码中的任何位置访问 ngrok_address
