Question

我是新来的烧瓶Restful api我正在尝试制作一个获取JSON数据的休息api。虽然输入curl命令我得到404错误。这是代码可以任何人请帮助。

#flask/bin/python
from flask import Flask, jsonify, abort, request, make_response,url_for,render_template
from flask.ext.restful import Api, Resource
#from flask.ext.restful import restful, Api
app = Flask(__name__, static_folder ="\Flae\app\default")
api= Api(app)

@app.errorhandler(404)
def page_not_found(e):
return 'Sorry, Nothing at this URL.', 404


class Task(Resource):

    tasks = [
        {
            'id': 1,
            'message': u'You are notified'
        },
        {
            'id': 2,
            'message': u'You are notified'
        }
    ]

    def get_tasks():
        return jsonify( { 'tasks': tasks } )

api.add_resource(Task, '/api/v1/tasks')

if __name__ == '__main__':
    app.run()

显示的错误是：

  C:\Users\Chaitanya>curl http://127.0.0.1:5000/
  Sorry, Nothing at this URL.
  C:\Users\Chaitanya>curl http://127.0.0.1:5000/api/v1/tasks
  {"status": 500, "message": "Internal Server Error"}
  C:\Users\Chaitanya>

生成的日志是：
