JSON模式驗證 - 爲什麼不需要強制執行？

Question

我一直在試圖創建一個JSON Schema並且使用在線驗證工具http://jsonschemalint.com/。我對我的JSON對象做了一些改變，我預計會對我的模式失敗，但它沒有 - 所以我認爲我一定在某個地方犯了錯誤。任何人都可以解釋爲什麼以下更改不會導致驗證錯誤？

變化

在enabled或display依賴項下找到「targetID」：「ConfigType」。刪除這一行。這應該會失敗，因爲這些都是根據模式的必需字段。然而，它似乎並沒有失敗...

Answer 1

首先，我會建議你轉移到草案4有一些改進（需要提供一個數組）。

jsonschemalint正在使用草案3.Afaik「項目」約束沒有改變。您可以提供一個布爾值，一個對象或一個對象數組。

就你而言，你提供了一個對象模式，但不正確。 「組」和「配置」標籤是沒有必要的。例如，給出下面的JSON對象在草案3：

[{}] 

此架構（如您的類似）對數據進行驗證：

{ 
    "type" : "array", 
"minItems" : 1, 
"items" : { 
    "unnecesaryLabel" : { 
     "type" : "object", 
     "properties" : { 
      "one" : { 
       "required" : true 
      } 
     } 
    } 
} 
} 

，這使得數據無效：

{ 
"type" : "array", 
"minItems" : 1, 
"items" : { 
    "type" : "object", 
    "properties" : { 
     "one" : { 
      "required" : true 
     } 
    } 
} 
}
