我试图在部署后获取flask_ngrok或py-ngrok的生成域名或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 You can now login through https://aaf8447ee878.ngrok.io/

我已经尝试检查目录并阅读了一些帮助，但我仍然无法得到它。提前谢谢❤</p>

    system = platform.system()
    if system == "Darwin":

####################

不要在name == ' main '之前的末尾导入 flask_ngrok添加此功能

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

在 app.run() 之前放

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

并运行警告：如果您不希望在 ngrok url 函数中使用您想要对 url 执行的任何操作替换 print，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)

您也可以在导入集 之后删除名称== ' 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

我发现最简单的方法是在用户访问网站时复制 url。您可以通过...

@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'
