问题描述
我正在使用 Python Web 应用程序控制 RaspBerry Pi GPIO 引脚。它在我使用flask-test-server的测试中工作正常，但它不能在另一个网络或互联网上工作。树莓派在局域网中，通过路由器的 DMZ 和 80 端口和互联网中的 Apache2 可见。引脚状态在我的测试中工作正常，但它在另一个网络中不起作用，尽管它从另一个网络访问我的服务器但没有改变 GPIO 引脚的状态。所以我知道“如果 request.method == 'POST'” 在“ @app.route('/profile',methods=['GET','POST']) "在我的代码中无法正常工作，但我不知道为什么 ???!!!!
