python代码

from flask import Flask, request, jsonifyapp = Flask(__name__)#用/data路径路由
@app.route('/data')
def get_data():## 以下一行是从URL中获取参数的get方法data = request.args.get('data')return jsonify(data = data,info = "success !",code = "200"
)if __name__ == '__main__':app.debug = Trueapp.run(host='192.111.111.111', port=5555)# app.run()

get方法可以不需要任何前端代码，直接运行以上Python代码，控制端会有以下输出

 * Serving Flask app 'flask_service'* Debug mode: on
WARNING: This is a development server. Do not use it in a production deployment. Use a production WSGI server instead.* Running on http://127.0.0.1:5000
Press CTRL+C to quit* Restarting with stat* Debugger is active!* Debugger PIN: 631-444-681

http://127.0.0.1:5000为我们的URL，因为我们做了/data的路由，所以在浏览器地址栏输入http://127.0.0.1:5000/data?data=2013.9

页面可以返回python文件中设定的json格式数据：

{"code": "200","data": "2013.4.4","info": "success !"
}
