Flask 服务器设置host=0.0.0.0之后外部仍然无法访问，使用命令python *.py run启动OK

IP设置成0.0.0.0，还是不能外部访问

if __name__ == '__main__':
    app.run(host="0.0.0.0", port=5000, debug=True)

使用的Pycharm IDE，使用的三角号运行的Flask程序，启动后，显示信息仍然是127.0.0.1:5000

 * Serving Flask app "app.py"
 * Environment: development
 * Debug mode: off
 * Running on http://127.0.0.1:5000/ (Press CTRL+C to quit)

百度一下，发现有IDE造成的问题，改用命令行运行Flask程序，之后正常了，可以外部访问了

(venv) D:\pycharm\sensor_test>python app.py
