用于分页的函数
如果 url 里面不含有paging=true，那么将返回全部数据。类似
[
{
"username": "1111111",
"password": "123456"
}
]
如果 url 中有 paging=true 的参数，
然后还需要读取其余的两个参数，page=[int]，需要的页码，p
age_size=[int]，一页的数据条数
参数错误的时候，返回{"code": 1, "data": u"参数错误"}
返回的数据格式
{
"code": 0,
"data": {
"previous_page": null,
"results": [
{
"username": "1111111",
"password": "123456"
}
],
"next_page": 2
}
}
