Python：使用 cerberus 进行验证

Question

我想验证 a dict，其中字段可能包含 anint或 a List[int]。此外，一切都int必须是积极的。我需要一些帮助来设置架构。下面的架构无法正常工作。他们不检查负数。也就是说，负数正在通过验证，这是不正确的。import cerberusv = cerberus.Validator()schema1 = {    "int_or_list_of_int": {        "type": ["integer", "list"],        "schema": {"type": "integer", "min": 0},    },}schema2 = {    "int_or_list_of_int": {        "type": ["integer", "list"],        "valuesrules": {"type": "integer", "min": 0},    },}num1 = {"int_or_list_of_int": 5}num2 = {"int_or_list_of_int": [5, 10]}num3 = {"int_or_list_of_int": -5}num4 = {"int_or_list_of_int": [5, -10]}# schema 1assert v.validate(num1, schema1)assert v.validate(num2, schema1)assert not v.validate(num3, schema1)  # Evaluates to Trueassert not v.validate(num3, schema1)  # Evaluates to True# schema 2assert v.validate(num1, schema2)assert v.validate(num2, schema2)to Trueassert not v.validate(num3, schema2)  # Evaluates to Trueassert not v.validate(num4, schema2)  # Evaluates to True

Answer 1

首先，schemaforint_or_list_of_int应该在int_or_list_of_intdict里面。其次，min应该适用于整数（内部int_or_list_of_int）和列表（内部schema）。

schema = {

    "int_or_list_of_int": {

        "type": ["integer", "list"],

        "min": 0,

        "schema": {"type": "integer", "min": 0}

    }

}
