根据 JSON Schema C# 验证 JSON [英] Validate JSON against JSON Schema C#

问题描述

有没有办法根据该结构的 JSON 模式验证 JSON 结构?我查看并发现了 JSON.Net 验证，但这并没有达到我想要的效果.

Is there a way to validate a JSON structure against a JSON schema for that structure? I have looked and found JSON.Net validate but this does not do what I want.

JSON.net 确实:

JsonSchema schema = JsonSchema.Parse(@"{
  'type': 'object',
  'properties': {
    'name': {'type':'string'},
    'hobbies': {'type': 'array'}
  }
}");

JObject person = JObject.Parse(@"{
  'name': 'James',
  'hobbies': ['.NET', 'LOLCATS']
}");

bool valid = person.IsValid(schema);
// true

这验证为真.

JsonSchema schema = JsonSchema.Parse(@"{
  'type': 'object',
  'properties': {
    'name': {'type':'string'},
    'hobbies': {'type': 'array'}
  }
}");

JObject person = JObject.Parse(@"{
  'surname': 2,
  'hobbies': ['.NET', 'LOLCATS']
}");

bool valid = person.IsValid(schema);

这也验证为真

JsonSchema schema = JsonSchema.Parse(@"{
  'type': 'object',
  'properties': {
    'name': {'type':'string'},
    'hobbies': {'type': 'array'}
  }
}");

JObject person = JObject.Parse(@"{
  'name': 2,
  'hobbies': ['.NET', 'LOLCATS']
}");

bool valid = person.IsValid(schema);

仅此验证为 false.

Only this validates to false.

理想情况下，我希望它验证那里没有不应该在那里又名 surname 的字段，即 name.

Ideally I would like it to Validate that there are no fields aka name in there that shouldn't be in there aka surname.

推荐答案

我认为你只需要添加

'additionalProperties': false

到您的架构.这将停止提供未知的属性.

to your schema. This will stop unknown properties being provided.

所以现在你的结果将是:-对、错、错

So now your results will be:- True, False, False

测试代码....

void Main()
{
var schema = JsonSchema.Parse(
@"{
    'type': 'object',
    'properties': {
        'name': {'type':'string'},
        'hobbies': {'type': 'array'}
    },
    'additionalProperties': false
    }");

IsValid(JObject.Parse(
@"{
    'name': 'James',
    'hobbies': ['.NET', 'LOLCATS']
  }"), 
schema).Dump();

IsValid(JObject.Parse(
@"{
    'surname': 2,
    'hobbies': ['.NET', 'LOLCATS']
  }"), 
schema).Dump();

IsValid(JObject.Parse(
@"{
    'name': 2,
    'hobbies': ['.NET', 'LOLCATS']
  }"), 
schema).Dump();
}

public bool IsValid(JObject obj, JsonSchema schema)
{
    return obj.IsValid(schema);
}

输出:-

True
False
False

您还可以将 "required":true 添加到必须提供的字段中，这样您就可以返回包含缺少/无效字段详细信息的消息:-

You could also add "required":true to the fields that must be supplied that way you can return a message with details of missing/invalid fields:-

Property 'surname' has not been defined and the schema does not allow additional     properties. Line 2, position 19. 
Required properties are missing from object: name. 

Invalid type. Expected String but got Integer. Line 2, position 18.
