Flask 开启服务后，默认是本机访问的，使用localhost:5000可以访问Web服务，但是使用如192.168.1.10这类本机IP地址却访问不了。
启动Falsk服务后信息如下，
1 2 3 4 5 6 7 8 9

* Serving Flask app "app" (lazy loading) * Environment: production WARNING: Do not use the development server in a production environment. Use a production WSGI server instead. * Debug mode: on * Restarting with stat * Debugger is active! * Debugger PIN: 228-080-042 * Running on ://127.0.0.1:5000/ (Press CTRL+C to quit)

除本机外是不能访问的，需要在run参数中设置,端口自定，主机为0.0.0.0

app.run(host='0.0.0.0', port=5000)

再次启动后就可以了。
