flask web后台启动后会发现默认是 localhost 127.0.0.1:5000
如果需要修改,方便调试发布
可以采用以下方式运行
from flask import Flask
from flask import request
app = Flask(__name__)
@app.route('/')
def index():
user_agent=request.headers.get('User_Agent')
return 'user_agent is %s' %user_agent
if __name__ == '__main__':
app.run(
host='0.0.0.0',
port= 5000,
debug=True
)
结果如下
- Serving Flask app “start” (lazy loading)
- Environment: production
WARNING: Do not use the development server in a production environment.
Use a production WSGI server instead. - Debug mode: on
- Running on http://0.0.0.0:5000/ (Press CTRL+C to quit)
