針對JSON模式的JSON驗證：爲什麼這個顯而易見的JSON數據沒有通過驗證

Question

這個JSON文件應該驗證失敗，但它沒有驗證。有人告訴我爲什麼。

插件以下JSON數據和模式進入這個網站，驗證，
http://json-schema-validator.herokuapp.com 和我的騾子驗證JSON模式相同的結果。它顯然不符合模式（我添加了一些字段，我拼錯了一些字段，日期時間值不是真正的日期時間），但它並沒有使它失敗。有人能告訴我爲什麼嗎？

JSON模式：

Answer 1

它不會失敗，因爲你的架構沒有任何強制約束。請注意，definitions不是jsonschema關鍵字，表示約束驗證。它通常用於放置在模式定義的其他部分重新使用的子模式。因此，首先，您應該更改definitions關鍵字properties。

jsonschema另一個常見的誤解與properties關鍵字有關。讓我們來看看下面的例子：

{ 
    "type" : "object", 
    "properties" : { 
     "key1" : { 
      "type" : "string" 
     } 
    } 
} 

你必須把它讀作：json必須是一個對象，並且它包含一個鍵等於key1的情況下，其值必須是一個字符串。根據以下兩個JSON對象是有效的：

{ 
    "key2":12 
} 

和：

{ 
    "key1":"sdf" 
} 

最後，涉及到date-time格式，你必須檢查section 6 of RFC3339，以確保你有一個有效的日期時間。在任何情況下，jsonschema驗證器都不是強制實施格式。

謝謝@jruizaranguren我還了解到，我需要將 「additionalProperties」：false和「required」：確保在API中傳遞什麼是預期的。

以下是我如何解決我的問題。

    "$schema": "http://json-schema.org/draft-04/schema#", 
    "type": "object",

     "required": [ 
     "auditCorrelationId", 
     "serviceRequestTimestamp", 
     "serviceProvider", 
     "serviceProviderVersion", 
     "serviceProviderTimestamp", 
     "eventType", 
     "hostName", 
     "sourceSystem", 
     "authenticationId" 
     ],
