pythonish-validator 0.4.1

安装

pip3 install pythonish-validator

错误消息

from pythonish_validator.common import validate

validator= validate({'name': str,
    'age': int,
    'skills': [str]}, {'name': 'Georgy',
    'age': None,
    'skills': ['Python', 'Perl', 42]})

assert validator.repr_errors()==["{'age'}->NoneType(None)",
    "{'skills'}->[2]->int(42)"]

功能

使用python类的语言：

from pythonish_validator.common import Validator


class User:
    __validation_schema__={'id': int,
        'name': str
    }validator= Validator({"users": [User]})# valid structure
validator.is_valid({"users": [{'id': 1, 'name': 'Alice'},
        {'id': 2, 'name': 'Bob'},
    ]})# invalid structure
validator.is_valid({"users": [{'id': '1', 'name': 'Alice'},
        {'id': 2},
    ]})

assert validator.repr_errors()==["{'users'}->[0]->{'id'}->str('1')",
    "{'users'}->[1]->{'name'}",
]

甚至自定义验证：

import re

from pythonish_validator.common import Validator


class EmailType:
    @staticmethod
    def __validation_schema__(data):
        if not isinstance(data, str):
            return False

        if re.match(r'\w+@\w+.\w{2,5}', data) is None:
            return False

        return True


class User:
    __validation_schema__={'id': int,
        'name': str,
        'email': EmailType,
    }validator= Validator({"users": [User]})

validator.is_valid({"users": [{'id': 1, 'name': 'Alice', 'email': 'alice@example.com'},
        {'id': 2, 'name': 'Bob', 'email': 'bob@example.com'},
    ]})
