public static class WebApiConfig
{
public static void Register(HttpConfiguration config)
{
// Web API 配置和服务 // Web API 路由
config.MapHttpAttributeRoutes(); config.Routes.MapHttpRoute(
name: "DefaultApi",
routeTemplate: "api/{controller}/{id}",
defaults: new { id = RouteParameter.Optional }
); config.Routes.MapHttpRoute(
name: "ActionApi",
routeTemplate: "{controller}/{action}/{id}",
defaults: new { id = RouteParameter.Optional }
); config.Formatters.JsonFormatter.AddQueryStringMapping("$format", "json", "application/json");
config.Formatters.XmlFormatter.AddQueryStringMapping("$format", "xml", "application/xml"); }
}
WebAPI 只使用JSON格式响应
public static class WebApiConfig
{
public static void Register(HttpConfiguration config)
{
// Web API 配置和服务 // Web API 路由
config.MapHttpAttributeRoutes(); config.Routes.MapHttpRoute(
name: "DefaultApi",
routeTemplate: "api/{controller}/{id}",
defaults: new { id = RouteParameter.Optional }
); config.Routes.MapHttpRoute(
name: "ActionApi",
routeTemplate: "{controller}/{action}/{id}",
defaults: new { id = RouteParameter.Optional }
); config.Formatters.XmlFormatter.SupportedMediaTypes.Clear();
}
}
使用方式
http://localhost:8081/api/home?$format=json
http://localhost:8081/api/home?$format=xml
