调用：

namespace Rongzi.RZR.Huoke.Filters

{

    public class ApiFormAuthFilterAttribute : System.Web.Mvc.ActionFilterAttribute

    {

        public AccountService AccountService { get; set; }

        public ApiFormAuthFilterAttribute()

        {

            this.AccountService = ContainerConfig.Resolve<AccountService>();

        }

        public override void OnActionExecuting(ActionExecutingContext actionContext)

        {

            if (actionContext == null || actionContext.HttpContext.Request == null || actionContext.HttpContext.Request.RawUrl == null) { return; }

            string OrgUserAccountInfo = actionContext.HttpContext.Request.QueryString["OrgUserAccountInfo"];

            if (!String.IsNullOrEmpty(OrgUserAccountInfo))

            {

                OrgUserAccountInfo info = new RSAEncryptHelper().DecryptString<OrgUserAccountInfo>(OrgUserAccountInfo);

                OrganizationUserModel oUser = AccountService.GetOrganizationUserByPhone(info.CellPhone);

                if (oUser == null || oUser.OrgId!=info.OrgId)

                {

                    actionContext.Result = GetAuthJsonResult("手机号或机构id错误"); return;

                }

                if (DateTime.Now.AddMinutes(-10) > info.timespan)

                {

                    actionContext.Result = GetAuthJsonResult("该链接已超时"); return;

                }

                FormsAuth.SignIn(oUser);

                base.OnActionExecuting(actionContext);

                return;

            }

            base.OnActionExecuting(actionContext);

        }

        public static JsonResult GetAuthJsonResult(string msg = "用户还未登录")

        {

            var errResponse = new ResponseContext<string>();

            errResponse.Head = new ResponseHead(-2, ErrCode.AuthError, msg);

            return new JsonResult

            {

                Data = errResponse,

                ContentEncoding = System.Text.Encoding.UTF8,

                JsonRequestBehavior = JsonRequestBehavior.AllowGet

            };

        }

        public override void OnActionExecuted(ActionExecutedContext actionExecutedContext)

        {

            base.OnActionExecuted(actionExecutedContext);

        }

    }

}

var obj = container.Resolve<Interface>(); //只有有特殊需求的时候可以通过这样的形式来拿。一般情况下没有必要这样来拿，因为AutoFac会自动工作

（即：会自动去类的带参数的构造函数中找与容器中key一致的参数类型，并将对象注入到类中，其实就是将对象赋值给构造函数的参数）
