与ASP.Net的Web API空值燮preSS性能
问题描述:
我已经创建了将移动应用程序中使用的ASP.Net WEB API项目。我需要的响应JSON省略空的属性,而不是返回它们作为属性:空
I've created an ASP.Net WEB API Project that will be used by a mobile application. I need the response json to omit null properties instead of return them as property: null
.
我怎样才能做到这一点?
How can I do this?
答
在 WebApiConfig
:
config.Formatters.JsonFormatter.SerializerSettings = new JsonSerializerSettings {NullValueHandling = NullValueHandling.Ignore};
或者,如果你想要更多的控制,可以更换整个格式:
Or, if you want more control, you can replace entire formatter:
var jsonformatter = new JsonMediaTypeFormatter
{
SerializerSettings =
{
NullValueHandling = NullValueHandling.Ignore
}
};
config.Formatters.RemoveAt(0);
config.Formatters.Insert(0, jsonformatter);
