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❤

添加

import atexit

import json

import os

import platform

import shutil

import subprocess

import tempfile

import time

import zipfile

from pathlib import Path

from threading import Timer

import requests

def _run_ngrok():

    ngrok_path = str(Path(tempfile.gettempdir(), "ngrok"))

    _download_ngrok(ngrok_path)

    system = platform.system()

    if system == "Darwin":

        command = "ngrok"

    elif system == "Windows":

        command = "ngrok.exe"

    elif system == "Linux":

        command = "ngrok"

    else:

        raise Exception(f"{system} is not supported")

    executable = str(Path(ngrok_path, command))

    os.chmod(executable, 777)

    ngrok = subprocess.Popen([executable, 'http', '5000'])

    atexit.register(ngrok.terminate)

    localhost_url = "http://localhost:4040/api/tunnels"  # Url with tunnel details

    time.sleep(1)

    tunnel_url = requests.get(localhost_url).text  # Get the tunnel information

    j = json.loads(tunnel_url)

    tunnel_url = j['tunnels'][0]['public_url']  # Do the parsing of the get

    tunnel_url = tunnel_url.replace("https", "http")

    return tunnel_url

def _download_ngrok(ngrok_path):

    if Path(ngrok_path).exists():

        return

    system = platform.system()

    if system == "Darwin":

        url = "https://bin.equinox.io/c/4VmDzA7iaHb/ngrok-stable-darwin-amd64.zip"

    elif system == "Windows":

        url = "https://bin.equinox.io/c/4VmDzA7iaHb/ngrok-stable-windows-amd64.zip"

    elif system == "Linux":

        url = "https://bin.equinox.io/c/4VmDzA7iaHb/ngrok-stable-linux-amd64.zip"

    else:

    download_path = _download_file(url)

    with zipfile.ZipFile(download_path, "r") as zip_ref:

        zip_ref.extractall(ngrok_path)

def _download_file(url):

    local_filename = url.split('/')[-1]

    ngrok_address = _run_ngrok()

    print(f" * Running on {ngrok_address}")

    print(f" * Traffic stats available on http://127.0.0.1:4040")

def run_with_ngrok(app):

    """

    The provided Flask app will be securely exposed to the public internet via ngrok when run,

    and the its ngrok address will be printed to stdout

    :param app: a Flask application object

    :return: None

    """

    old_run = app.run

    def new_run():

        thread = Timer(1, start_ngrok)

        thread.setDaemon(True)

        thread.start()

        old_run()

    app.run = new_run

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

不要在name == ' main '之前导入flask_ngrok添加此函数

def ngrok_url():

    global tunnel_url

    while True:

        try:

            print(ngrok_address)

        except Exception as e:

            print(e)

并在 app.run() 之前放置

thread = Timer(1, ngrok_url)

thread.setDaemon(True)

thread.start()

并运行警告：如果您不希望在 ngrok url 函数中将 print 替换为您想要对 url 执行的任何操作，这将使您的代码编辑器/或终端崩溃

Answer 2

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_request

def before_request():

    global url

    url = request.url

    # url = url.replace('http://', 'https://', 1)

    url = url.split('.ngrok.io')[0]

    url += '.ngrok.io'

Answer 3

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
