在JSON模式中使用RegEx [英] Using RegEx in JSON Schema
问题描述
尝试编写使用RegEx验证项目值的JSON模式.
具有一个名为 progBinaryName 的项目,其值应与该RegEx字符串"^[A-Za-z0-9 -_]+_Prog\\.(exe|EXE)$"
相同.
找不到任何能真正说明在JSON模式中使用RegEx的教程或示例.
任何帮助/信息将不胜感激!
谢谢, D

错误:
警告!最好检查一下您的JSON.
实例不是必需的类型- http://json-schema.org/draft-03/hyper-schema#
模式是有效的JSON,但不是有效的模式.

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"])
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)$"
}
}
}
P.S. -如果您希望模式与属性的 key 相匹配(而不是值),则应使用"patternProperties"
(就像"properties"
一样,但是键是RegEx).>
Trying to write a JSON schema that uses RegEx to validate a value of an item.
Have an item named progBinaryName whose value should adhrere to this RegEx string "^[A-Za-z0-9 -_]+_Prog\\.(exe|EXE)$"
.
Can not find any tutorials or examples that actually explain the use of RegEx in a JSON schema.
Any help/info would be GREATLY appreciated!
Thanks, D

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"])
To test a string value (not a property name) against a RegEx, you should use the "pattern"
keyword:
{
"type": "object",
"properties": {
"progBinaryName": {
"type": "string",
"pattern": "^[A-Za-z0-9 -_]+_Prog\\.(exe|EXE)$"
}
}
}
P.S. - if you want the pattern to match the key for the property (not the value), then you should use "patternProperties"
(it's like "properties"
, but the key is a RegEx).
