在JSON模式中使用RegEx

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,其值应该与此RegEx字符串相同"^[A-Za-z0-9 -_]+_Prog\\.(exe|EXE)$".

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/信息将非常感谢!

感谢:D

警告!更好地检查你的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

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)$"
        }
    }
}

PS - 如果你想让模式匹配属性的键(而不是值),那么你应该使用"patternProperties"(就像"properties",但键是RegEx).

Answer 2

您的JSON架构语法不正确.更改

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

至

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