在flask中处理自定义验证的正确方法是什么？

Question

以下是我使用自定义消息处理多个自定义验证的方法。

def social_login_validation(data):
    """Login validation schema."""
    schema = Schema({
        Required('first_name'):All(str, Length(min=1, max=30)),
        Required('last_name'):All(str, Length(min=1, max=30)),
        Optional('phone_number'):All(str, Length(min=10, max=10), validate_phone_number),
        Optional('profile_picture'):Any(str, Length(min=1, max=255)),
        Optional('email'):All(str, Length(min=10, max=255), validate_email),
        Optional('auth_token'):Any(str, Length(min=10, max=255)),
        Optional('auth_token_expiry_date'):Any(str, Length(min=10, max=255)),
        Required('social_media_login_type'):All(str, Length(min=1, max=255),\
                validate_social_media_login_type),
        Required('social_id'):All(str, Length(min=10, max=255))
    })
    try:
        schema(data)
    except MultipleInvalid as error:
        if "length" in str(error) and "['first_name']" in str(error) and "at most" in str(error):
            message = RESPONSES['LENGTH_FIRST_NAME']
            code = RESPONSES_CODE['BAD_REQUEST']
        elif "length" in str(error) and "['last_name']" in str(error) and "at most" in str(error):
            message = RESPONSES['LENGTH_LAST_NAME']
            code = RESPONSES_CODE['BAD_REQUEST']
        elif "length" in str(error) and "['social_media_login_type']"\
            in str(error) and "at most" in str(error):
            message = RESPONSES['LENGTH_LOGIN_TYPE']
            code = RESPONSES_CODE['BAD_REQUEST']
        elif "length" in str(error) and "['social_id']" in str(error) and "at most" in str(error):
            message = RESPONSES['LENGTH_SOCIAL_ID']
            code = RESPONSES_CODE['BAD_REQUEST']
        elif "length" in str(error) and "['phone_number']" in str(error):
            message = RESPONSES['LENGTH_PHONE_NUMBER']
            code = RESPONSES_CODE['BAD_REQUEST']
        elif "expected str" in str(error) and "['email']" in str(error):
            message = RESPONSES['TYPE_EMAIL']
            code = RESPONSES_CODE['BAD_REQUEST']
        elif "data['first_name']" in str(error):
            message = RESPONSES['EMPTY_FIRST_NAME']
            code = RESPONSES_CODE['BAD_REQUEST']
        elif "data['last_name']" in str(error):
            message = RESPONSES['EMPTY_LAST_NAME']
            code = RESPONSES_CODE['BAD_REQUEST']
        elif "data['social_media_login_type']" in str(error):
            message = RESPONSES['EMPTY_LOGIN_TYPE']
            code = RESPONSES_CODE['BAD_REQUEST']
        elif "data['social_id']" in str(error):
            message = RESPONSES['EMPTY_SOCIAL_ID']
            code = RESPONSES_CODE['BAD_REQUEST']
        else:
            return jsonify({'message':str(error.error_message)}), 400
        return jsonify({'message':message}), code

处理这些许多自定义消息的更好方法是什么？

看来您使用的是voluptuous包装？

您可能要使用软件包的humanize功能，而不是自己编写每个错误消息。

如果稍微看一下源代码 ，就会发现可以通过error.errors访问错误。 我会仔细研究一下，看看是否可以以比将错误转换为字符串小的方式改变错误的方式来访问错误。

我从未使用过此软件包，但请将其添加到问题标签中，以便人们知道他们在看什么。
