在JSON模式使用正则表达式(Using RegEx in JSON Schema)

尝试编写使用正则表达式来验证项目的值的JSON模式。

有一个名为progBinaryName一个项目，其价值应该adhrere这个正则表达式的字符串"^[A-Za-z0-9 -_]+_Prog\\.(exe|EXE)$"

找不到实际解释一个JSON模式使用正则表达式的任何教程或例子。

任何帮助/信息将不胜感激！

错误：

警告！ 更好地检查你的JSON。

模式是有效的JSON，但不是一个有效的模式。

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:

要测试字符串值（不是属性名）对正则表达式，你应该使用"pattern"的文章：

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

PS -如果你想在模式匹配的财产（不是值），那么你应该使用的关键 "patternProperties" （这就像"properties" ，但关键是一个正则表达式）。

Answer 2:

你的JSON模式语法不正确。 更改

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

至

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