信息发布系统 Jquery+MVC架构开发(7) Controller层

 Controller 这一层首先要添加对WCF 的引用：



如下，输入我们自己的wcf地址 http://localhost:8732/Design_Time_Addresses/InfoPub.BLLService/Service1/mex  
为了解析嵌套结构的类，我们加入JsonBinderusing System;using System.Collections.Generic;using System.Linq;using System.Web;using System.Web.Mvc;using System.Web.Script.Serialization; namespace InfoPub.Controllers{    public class JsonBinder<T> : IModelBinder    {        public object BindModel(ControllerContext controllerContext, ModelBindingContext bindingContext)        {            // 从䨮请?求¨®中D获?取¨?提¬¨¢交?的Ì?参?数ºy数ºy据Y             var json = controllerContext.HttpContext.Request.Form[bindingContext.ModelName] as string;             // 提¬¨¢交?参?数ºy是º?对?象¨®             if (json.StartsWith("{") && json.EndsWith("}"))            {                JavaScriptSerializer js = new JavaScriptSerializer();                object obj = js.Deserialize<T>(json);                return obj;            }             // 提¬¨¢交?参?数ºy是º?数ºy组Á¨¦             if (json.StartsWith("[") && json.EndsWith("]"))            {                JavaScriptSerializer js = new JavaScriptSerializer();                List<T> obj = js.Deserialize<List<T>>(json);                 return obj;            }              return null;        }    }}我们依次添加三个controller,Infocontroller,InfoTypeContrller,UserInfoContrller,如下：

注意我们添加空的controller即可，别的controller我们暂用不到，如下：

下面我们添加Controller方法，于InfoController为例说明：using System;using System.Collections.Generic;using System.Linq;using System.Web;using System.Web.Mvc;using InfoPub.InfoPubService; namespace InfoPub.Controllers{    public class InfoController : Controller    {        private InfoPubServiceClient infoPubService = new InfoPubServiceClient();         public JsonResult GetInfoList([ModelBinder(typeof(JsonBinder<SearchInfo>))]SearchInfo searchInfo)        {            InfoList infoList = new InfoList();            infoList = infoPubService.GetInfoList(searchInfo);            if (infoList.infoResult.Code != 0)            {                return Json(new { Data = infoList, isSuccess = false, message = "GetInfoList fail ", errorCode = infoList.infoResult.Code }, "text/json", JsonRequestBehavior.AllowGet);            }             return Json(new { Data = infoList, isSuccess = true }, "text/json", JsonRequestBehavior.AllowGet);        }         public JsonResult GetInfoById(int infoId)        {            InfoList infoList = new InfoList();            infoList = infoPubService.GetInfoById(infoId);            if (infoList.infoResult.Code != 0)            {                return Json(new { Data = infoList, isSuccess = false, message = "GetInfoById fail ", errorCode = infoList.infoResult.Code }, "text/json", JsonRequestBehavior.AllowGet);            }             return Json(new { Data = infoList, isSuccess = true }, "text/json", JsonRequestBehavior.AllowGet);        }         public JsonResult AddInfo(Info info)        {            InfoResult infoResult = new InfoResult();            infoResult = infoPubService.AddInfo(info);            if (infoResult.Code != 0)            {                return Json(new { Data = infoResult, isSuccess = false, message = "AddInfo fail ", errorCode = infoResult.Code }, "text/json", JsonRequestBehavior.AllowGet);            }             return Json(new { Data = infoResult, isSuccess = true }, "text/json", JsonRequestBehavior.AllowGet);        }         public JsonResult UpdateInfo(Info info)        {            InfoResult infoResult = new InfoResult();            infoResult = infoPubService.UpdateInfo(info);            if (infoResult.Code != 0)            {                return Json(new { Data = infoResult, isSuccess = false, message = "UpdateInfo fail ", errorCode = infoResult.Code }, "text/json", JsonRequestBehavior.AllowGet);            }             return Json(new { Data = infoResult, isSuccess = true }, "text/json", JsonRequestBehavior.AllowGet);        }         public JsonResult DeleteInfo(int infoId)        {            InfoResult infoResult = new InfoResult();            infoResult = infoPubService.DeleteInfo(infoId);            if (infoResult.Code != 0)            {                return Json(new { Data = infoResult, isSuccess = false, message = "DeleteInfo fail ", errorCode = infoResult.Code }, "text/json", JsonRequestBehavior.AllowGet);            }             return Json(new { Data = infoResult, isSuccess = true }, "text/json", JsonRequestBehavior.AllowGet);        }     }}
