针对JSON模式的JSON验证：为什么这个显而易见的JSON数据没有通过验证

Question

这个JSON文件应该验证失败，但它没有验证。有人告诉我为什么。

插件以下JSON数据和模式进入这个网站，验证，
http://json-schema-validator.herokuapp.com 和我的骡子验证JSON模式相同的结果。它显然不符合模式（我添加了一些字段，我拼错了一些字段，日期时间值不是真正的日期时间），但它并没有使它失败。有人能告诉我为什么吗？

JSON模式：

{

    "serviceAuditLogData": {

     "title": "serviceAuditLogData",

     "sourceSystem" 
     ],

Answer 1

它不会失败，因为你的架构没有任何强制约束。请注意，definitions不是jsonschema关键字，表示约束验证。它通常用于放置在模式定义的其他部分重新使用的子模式。因此，首先，您应该更改definitions关键字properties。

jsonschema另一个常见的误解与properties关键字有关。让我们来看看下面的例子：

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

你必须把它读作：json必须是一个对象，并且它包含一个键等于key1的情况下，其值必须是一个字符串。根据以下两个JSON对象是有效的：

{ 
    "key2":12 
} 

和：

{ 
    "key1":"sdf" 
} 

最后，涉及到date-time格式，你必须检查section 6 of RFC3339，以确保你有一个有效的日期时间。在任何情况下，jsonschema验证器都不是强制实施格式。

谢谢@jruizaranguren我还了解到，我需要将 “additionalProperties”：false和“required”：确保在API中传递什么是预期的。

以下是我如何解决我的问题。

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

     "additionalProperties": false, 
     "required": [ 
     "auditCorrelationId", 
     "serviceRequestTimestamp", 
     "serviceProvider", 
     "serviceProviderVersion", 
     "serviceProviderTimestamp", 
     "eventType", 
     "hostName", 
     "sourceSystem", 
     "authenticationId" 
     ], 
     "properties": {
