json schema校驗

工作中使用到了json schema格式校驗的問題，在網上查了些資料，結合自己的理解記錄一下。

json schema可以對json結果字符串做出一些約束，例如：

1. 值類型是：array, object, number, string等等

2.值類型必須是枚舉中的一個

3. 字符串的長度限制

4. 對字符串判斷是否符合正則表達式

5. array元素個數

6. object對象必要屬性

 

測試schema文件

{
    "$schema": "http://json-schema.org/draft-04/schema#",
    "title": "Product set",
    "type": "array",  5     "items": {
        "title": "Product",
        "type": "object",  8         "properties": {
            "name": {
                "type": "string"
            },
            "price": {
                "type": "number",
                "minimum": 0,
                "maximum":30,
                "exclusiveMinimum": true
            },
            "tags": {
                "type": "array",
                "items": {
                    "type": "string",
                    "minLength":10,
                    "maxLength":1024,
                    "pattern":"http://.*"
                },
                "minItems": 2, 27                 "uniqueItems": true
            },
            "city":{
              "type":"string",
              "enum" : ["bj", "sh", "hk"] 32             }
        },
        "required": ["name", "price"] 35     }
}

 

測試json

[
  {
    "name":"san",
    "price":29,
    "tags":["http://sdtr/sdg", "http://qwewret/qsdf"],
    "city":"bj"
  },
  {
    "name":"dong",
    "price":30,
    "tags":["http://test", "http://sina"],
    "city":"hk"
  },
]
