json对象判断相等

支持dict、list、普通数据类型对象比较

def compare(src, des):
   if type(src) != type(des):
      return False
   if isinstance(src, (str, int, float)):
      if src == des:
         return True
      else:
         return False
   elif isinstance(src, dict):
      if len(src) != len(des):
         return False
      keys = set(list(src.keys()) + list(des.keys()))
      for key in keys:
         if key not in src or key not in des:
            return False
         result = compare(src[key], des[key])
         if not result:
            return result
      return True
   elif isinstance(src, list):
      if len(src) != len(des):
         return False
      length = len(src)
      for i in range(length):
         for lj in des:
            result = compare(src[i], lj)
            if result:
               des.remove(lj) # des列表中的元素匹配上后，des.remove掉元素， len(des)会-1；
               break
         length -= 1
         if length != len(des):
            return False

   return True
