Question

尝试编写一个使用RegEx来验证项目值的JSON模式。

有一个名为 progBinaryName 的项目，其值应与此RegEx字符串"^[A-Za-z0-9 -_]+_Prog\\.(exe|EXE)$"相同。

找不到任何实际解释在JSON模式中使用RegEx的教程或示例。

任何帮助/信息都会非常感激！

谢谢， d

警告！更好地检查你的JSON。

实例不是必需类型 - http://json-schema.org/draft-03/hyper-schema#

架构是有效的JSON，但不是有效的架构。

Problem with schema#/properties/progBinaryName/patternProperties/progBinaryName : Instance is not a required type
Reported by http://json-schema.org/draft-03/hyper-schema#
Attribute "type" (["object"])

Answer 1

要针对RegEx测试字符串值（不是属性名称），您应该使用"pattern"关键字：

{
    "type": "object",
    "properties": {
        "progBinaryName": {
            "type": "string",
            "pattern": "^[A-Za-z0-9 -_]+_Prog\\.(exe|EXE)$"
        }
    }
}

P.S。 - 如果您希望模式匹配属性的键（而不是值），那么您应该使用"patternProperties"（它类似于"properties"，但关键是RegEx ）。

Answer 2

您的JSON架构语法不正确。变化

"patternProperties": {
    "progBinaryName": "^[A-Za-z0-9 -_]+_Prog\\.(exe|EXE)$"
    }

到

"patternProperties": {
    "^[A-Za-z0-9 -_]+_Prog\\.(exe|EXE)$": {}
    }

在JSON模式中使用RegEx
