jsoncensor
Check json data in your python web service.
作用
1,检查key数目是否一致
2,检查key是否一致
3,检查value的type是否一致, 若value为一个对象，则递归地检查它的key number，Key name, value type.
Usage
Support both python2.7 and python3
pip install jsoncensor
创建一个标准json数据的字典，把它和待检查字典作为初始化JsonCensor对象的参数传入
调用JsonCensor对象的check方法.
from jsoncensor import JsonCensor
standard = {...}
suspect = {...}
jc = JsonCensor(standard, suspect)
ret = jc.check()
if ret['statu'] == True:
print("ok")
else:
print(ret)
返回结构体:
{
"statu": True Or False,
"error": string 若有错误为错误类型，否则为None,
"error_indicator": string 错误对象的字符串,
"should_be": string 错误对象应有的状态
}
