>>> from requests import put, get

>>> put('http://localhost:5000/todo1', data={'data': 'Remember the milk'}).json()

{u'todo1': u'Remember the milk'}

>>> get('http://localhost:5000/todo1').json()

{u'todo1': u'Remember the milk'}

>>> put('http://localhost:5000/todo2', data={'data': 'Change my brakepads'}).json()

{u'todo2': u'Change my brakepads'}

>>> get('http://localhost:5000/todo2').json()

{u'todo2': u'Change my brakepads'}

语法：先导入requests中的方法，然后方法名('${url}',data={key:value}).json()
