无法将从用户接收的Json转换为我的API服务器API中的类型

Question

我开发了一个web API，它接收json并将其转换为我预定义的格式，然后将其写入文件中。

当客户端尝试发送put请求时，我在服务器上收到以下json：

{
  "_entities": [
    {
      "_name": "wizardaccessprivilege",
      "_SourceUniqueId": "e",
      "_isIncludedInLibrary": false,
      "_isCustomEntity": false,
      "_sourceSchemaName": "WizardAccessPrivilege",
      "_isIncludedInConnection": false,
      "_uniqueId": "9",
      "_hasChanged": "",
      "_associatedLibrary": {
        "_description": "Privilege needed to access a Web-based wizard."
      },
      "_defaultLabel": "Web Wizard Access Privilege",
      "_description": "Privilege needed to access a Web-based wizard.",
      "_sourceApplication": 0,
      "_lastModifiedDate": ""
    },
    {
      "_name": "egcsapps_fcrisksubcategory",
      "_SourceUniqueId": "7",
      "_isIncludedInLibrary": false,
      "_isCustomEntity": true,
      "_sourceSchemaName": "egory",
      "_isIncludedInConnection": false,
      "_uniqueId": "f",
      "_hasChanged": "",
      "_associatedLibrary": {
        "_description": ""
      },
      "_defaultLabel": "FC Risk Subcategory",
      "_description": "",
      "_sourceApplication": 0,
      "_lastModifiedDate": ""
    }
        ]
}

而我的对象结构是：

{
  "_sourceClientVersionStamp": "06/05/2019 15:25:27",
  "_organizationName": null,
  "_organizationServerName": null,
  "_domain": null,
  "_workspace": null,
  "_entities": [
    {
      "_uniqueId": "gg",
      "_name": "wizardaccessprivilege",
      "_sourceSchemaName": "WizardAccessPrivilege",
      "_isCustomEntity": false,
      "_isIncludedInLibrary": false,
      "_isIncludedInConnection": false,
      "_SourceUniqueId": "e",
      "_sourceApplication": 0,
      "_sourceApplicationVersion": "5.0.0.0",
      "_defaultLabel": "Web Wizard Access Privilege",
      "_localizedLabels": null,
      "_lastModifiedDate": null,
      "_fields": null,
      "_daysSinceRecordLastModified": 0,
      "_hasChanged": null,
      "_description": "Privilege needed to access a Web-based wizard.",
      "_associatedLibrary": {
        "_library": null,
        "_libraryFolder": "/",
        "_name": null,
        "_description": ""
      },
      "_entityRelationshipSet": [],
      "_connectionSet": []
    }
  ]
}

如何将从user收到的json转换为我的类型？在请求中，我有我的对象的一个属性

注意:我使用了这个，但不起作用：

     [Route("api/entity/UpdateConfigurationForLibrary")]
     [HttpPut]
     public void UpdateConfigurationForLibrary([FromBody] JObject data)
     {

       string output = JsonConvert.SerializeObject(data);
       EntitySet dEntitiesOnly = JsonConvert.DeserializeObject<EntitySet>(output);
..
}

Answer 1

Route("api/entity/UpdateConfigurationForLibrary")]
[HttpPut]
public void UpdateConfigurationForLibrary([FromBody] EntitySet entity)
{
...
}

如果您的JSON包含一个对象列表，只需将[FromBody] EntitySet entity更改为[FromBody] List<EntitySet> entities。

如果属性名称匹配，或者如果您使用[JsonProperty("propertyName")]属性正确地修饰了属性，那么框架就足够智能，可以将您的JSON映射到类类型。
