使用pycharm打开fish文件夹，新建一个fisher.py文件
from flask import Flask from flask_restful import Api,Resource app = Flask(__name__) api = Api(app) class HelloWorld(Resource): def get(self): return {'hello': 'world'} api.add_resource(HelloWorld, '/') if __name__ == '__main__': app.run(debug=True)
命令行运行
(fish) macname@MacdeMBP fish % python3 fisher.py * Serving Flask app "fisher" (lazy loading) * Environment: production WARNING: This is a development server. Do not use it in a production deployment. Use a production WSGI server instead. * Debug mode: on * Running on http://127.0.0.1:5000/ (Press CTRL+C to quit) * Restarting with stat * Debugger is active! * Debugger PIN: 315-121-294
打开浏览器
测试
from flask import Flask app = Flask(__name__) app.run()
