pycharm2019 flask项目, 允许通过外网IP地址访问，而非127.0.0.1

from flask import Flask
 
app = Flask(__name__)
 
 
@app.route('/hi')
def hello_world():
    return 'Hello World!'
 
 
if __name__ == '__main__':
    app.run(debug=True,host='0.0.0.0', port=8080)


运行输出：
FLASK_APP = app.py
FLASK_ENV = development
FLASK_DEBUG = 1
In folder D:/python/lean/site1
D:\python\lean\site1\venv\Scripts\python.exe -m flask run --host=0.0.0.0

在其他环境下,设定访问ip与 端口,直接在最后一句设定好host 和port就好.但在pycharm2018， pycharm2019 中不行.需要去

run-Edit-Configuration 中,找到Additinal options栏 ：手动写入 --host=x.x.x.x --port=xxxx。

好坑....
