在 JSON 模式中使用 RegEx

Question

尝试编写使用 RegEx 验证项目值的 JSON 模式。

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

找不到任何教程或示例来实际解释在 JSON 模式中使用 RegEx。

任何帮助/信息将不胜感激！

谢谢， D

警告！最好检查你的 JSON。

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

您的 JSON 架构语法不正确。改变

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

到

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

Answer 2

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)$"
        }
    }
}

附： - 如果您希望模式匹配属性的 key（而不是值），那么您应该使用 "patternProperties"（类似于 "properties"，但键是 RegEx）。
