WebAPI 笔记

一、基本配置

---

　　1. 全局配置 Global.asax

public class WebApiApplication : System.Web.HttpApplication
{
　　protected void Application_Start()
　　{
　　　　GlobalConfiguration.Configure(WebApiConfig.Register);
　　　　GlobalConfiguration.Configuration.Filters.Add(new WebApiActionDebugFilter());

　　　　//配置返回的时间类型数据格式 
　　　　GlobalConfiguration.Configuration.Formatters.JsonFormatter.SerializerSettings.Converters.Add(
　　　　　　new Newtonsoft.Json.Converters.IsoDateTimeConverter()
　　　　{
　　　　　　DateTimeFormat = "yyyy-MM-dd HH:mm:ss"
　　　　}
　　　　);
　　　　GlobalConfiguration.Configuration.Formatters.XmlFormatter.SupportedMediaTypes.Clear();

　　}
}

　　2. 日志记录 WebApiActionDebugFilter
