Flask 服務器設置host=0.0.0.0之后外部仍然無法訪問， 使用命令python *.py run啟動OK

IP設置成0.0.0.0，還是不能外部訪問

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

 

使用的Pycharm IDE，使用的三角號運行的Flask程序，啟動后，顯示信息仍然是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，發現有IDE造成的問題，改用命令行運行Flask程序，之后正常了，可以外部訪問了

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