ajv validate failed with correct schema「data should not have additional properties」

Question

我使用ajv在寫入數據庫之前驗證一些JSON數據。我的請求數據基本上看起來像這樣（作爲一個例子）：

DOC：

"name": "John", 
"id": "123-456-789" 

這被傳遞到ajv驗證：

const validator: ajv.Ajv = this.getValidator(); 
validator.validate("Testschema.out", doc) 

這是Testschema.out樣子

{ 
    "id": "Testschema.out", 
    "type": "object", 
    "allOf": [{ 
      "$ref": "anotherId#/definitions/someDefinition" 
     }, 
     { 
      "$ref": "Testschema" 
     } 
    ] 
} 

Testschema認爲：

{ 
    "id": "Testschema", 
    "type": "object", 
    "properties": { 
     "name": { 
      "type": "string" 
     } 
    }, 
    "additionalProperties": false, 
    "required": [ 
     "name" 
    ] 
} 

雖然someDefinition保持此：

{ 
    "id": "anotherId", 
    "type": "object", 
    "definitions": { 
     "someDefinition": { 
      "type": "object", 
      "properties": { 
       "id": { 
        "type": "string" 
       } 
      } 
     } 
    } 
} 

然而，驗證失敗，而我得到的錯誤是"data should NOT have additional properties"具體來說，由於某種原因，「anotherId」模式的任何驗證失敗。如果我在哪裏添加「id」屬性到Testschema，那麼驗證就會通過。

原來問題出在「Testschema」上的allOf關鍵字和"additionalProperties": false。請參閱：https://spacetelescope.github.io/understanding-json-schema/reference/combining.html#allof

看來，新$merge關鍵字是這個答案：https://github.com/epoberezkin/ajv-merge-patch
