我可以获取flask_ngrok或py-ngrok的生成的IP地址或域名并将其返回到127.0.0.1/

问题描述

我正在尝试获取部署后生成的flask_ngrok或py-ngrok的域名或IP地址。我想将flask_app部署到localhost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 您现在可以通过https://aaf8447ee878.ngrok.io/

我尝试检查目录并阅读一些帮助，但仍然无法获取。在此先感谢❤

不要导入flask_ngrok 最后在 name == 'ma​​in' 之前添加这个函数

def ngrok_url():
    global tunnel_url
    while True:
        try:
            print(ngrok_address)
        except Exception as e:
            print(e)

和之前的 app.run() 放置

thread = Timer(1,ngrok_url)
thread.setDaemon(True)
thread.start()

并运行警告：如果您不希望在 ngrok url 函数中使用任何您想对 url 执行的操作替换打印，这将使您的代码编辑器/或终端崩溃

,

你不需要那个

global tunnel_url
def ngrok_url():
    while True:
        try:
            print(ngrok_address)
        except Exception as e:
                print(e)

导入集后也可以删除name == 'ma​​in'之前的线程部分 ngrok_address = '' 然后你可以在代码中的任何地方访问 ngrok_address

我发现最简单的方法是在用户访问网站时复制网址。你可以这样做...

@app.before_request
def before_request():
    global url
    url = request.url
    # url = url.replace('http://','https://',1)
    url = url.split('.ngrok.io')[0]
    url += '.ngrok.io'
