python对两个json文件排序并判断两个json文件是否相等

方法1：递归比较每一个字段。
缺点：对jsonArray中每个字段需要特殊处理并排序。

    x1 = [{"nrfProfileId": "12345678-provision-0001", "servingPlmn": {"mcc": "310", "mnc": "003"},

方法2：对dict和list对象的json分别进行排序
优点：代码简洁通用。

def ordered(obj):
    if isinstance(obj, dict):
        return sorted((k, ordered(v)) for k, v in obj.items())
    if isinstance(obj, list):
        return sorted(ordered(x) for x in obj)
    else:
        return obj

    yy = {"111": None,
          "23456": {"22222": 9999, "33333": "0000"}}
    x1 = [{"nrfProfileId": "12345678-provision-0001", "servingPlmn": {"mcc": "310", "mnc": "003"},

    print(ordered(x1)==ordered(x2))
