Correct way to define array of enums in JSON schema
提问by senasi
I want to describe with JSON schema array, which should consist of zero or more predefined values. To make it simple, let's have these possible values: one, twoand three.
我想用 JSON 模式数组来描述，它应该由零个或多个预定义值组成。为了简单起见，让我们有这些可能的值：one,two和three。
Correct arrays (should pass validation):
正确的数组（应该通过验证）：
[]
["one", "one"]
["one", "three"]
Incorrect:
不正确：
["four"]
Now, I know the "enum"property should be used, but I can't find relevant information where to put it.
现在，我知道"enum"应该使用该属性，但找不到相关信息将其放在哪里。
Option A (under "items"):
选项A（下"items"）：
{
"type": "array",
"items": {
"type": "string",
"enum": ["one", "two", "three"]
}
}
Option B:
选项 B：
{
"type": "array",
"items": {
"type": "string"
},
"enum": ["one", "two", "three"]
}

According to the json-schemadocumentation, the enumerated values of an arraymust be included in the "items"field:
根据json-schema文档，字段中array必须包含an 的枚举值"items"：
{
"type": "array",
"items": {
"type": "string",
"enum": ["one", "two", "three"]
}
}
If you have an arraythat can hold e.g. items of different type, then your schema should look like the one below:
如果您有一个array可以容纳不同类型的项目，那么您的架构应该如下所示：
{
"type": "array",
"items": [
{
"type": "string",
"enum": ["one", "two", "three"]
},
{
"type": "integer",
"enum": [1, 2, 3]
}
]
}
