webconfig 中增加配置：

<system.webServer>
<httpProtocol>
<customHeaders>
<add name="Access-Control-Allow-Origin" value="*" />
<add name="Access-Control-Allow-Headers" value="Origin,X-Requested-With,Content-Type,accept,key" />
<add name="Access-Control-Allow-Methods" value="GET, POST, PUT, DELETE, OPTIONS" />
</customHeaders>
</httpProtocol>
</system.webServer>

Global.asax.cs文件中增加对于options支持

protectedvoid Application_BeginRequest(object sender, EventArgs e)
        {
var req = System.Web.HttpContext.Current.Request;
if (req.HttpMethod == "OPTIONS")//过滤options请求，用于js跨域
            {
                Response.StatusCode = 200;
                Response.SubStatusCode = 200;
                Response.End();
            }
        }
