在JSON模式中使用RegEx

尝试编写使用RegEx验证项目值的JSON模式。

有一个名为 的项目，该项目的值应预适应此RegEx字符串"^[A-Za-z0-9

-_]+_Prog\\.(exe|EXE)$"。

找不到任何实际解释JSON模式中RegEx用法的教程或示例。

任何帮助/信息将不胜感激！

感谢：D

警告！更好地检查您的JSON。

实例不是必需的类型-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"])

回答：

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

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

PS-如果您希望模式与属性的 键

（而不是值）相匹配，则应使用"patternProperties"（就像"properties"，但键是RegEx）。
