Question

有什么方法可以在JSON模式中将数组定义为非空？

Answer 1

如您在documentation中看到的那样，您可以使用"minItems": 1定义最小的项目数:

{
    "id": "http://some.site.somewhere/entry-schema#",
    "$schema": "http://json-schema.org/draft-04/schema#",
    "description": "schema for an fstab entry",
    "type": "object",
    "properties": {
        "options": {
            "type": "array",
            "minItems": 1, // -> array must not be empty
            "items": { "type": "string" },
            "uniqueItems": true
        },
        "readonly": { "type": "boolean" }
    }
}
