原因是api里面写了注入参数，还有web.config里面也有，去到web.config里面那部分配置就可以了。
//授权的请求域名
actionContext.Response.Headers.Add("Access-Control-Allow-Origin", Origin);
//授权的请求方式
actionContext.Response.Headers.Add("Access-Control-Allow-Methods", "*"); //GET,POST,PUT,DELETE,OPTION
actionContext.Response.Headers.Add("Access-Control-Allow-Headers", "x-requested-with");
actionContext.Response.Headers.Add("Access-Control-Allow-Credentials", "true");
