webapi返回泛型给easyui

由于之前遇到的easyui调用webapi的问题。

参见 ：http://blog.csdn.net/hanjun0612/article/details/51144991

所以就考虑，封装一个泛型用来返回 HttpResponseMessage

直接上代码：

泛型封装：

public class APIResult<T> : HttpResponseMessage
    {
        private T Data;

        public APIResult(T Data, string DataType = "application/json")
        {
            this.Data = Data;
            string jsonStr = GetJson(this.Data);
            this.Content = new StringContent(jsonStr, System.Text.Encoding.UTF8, DataType);
        }
//返回值
        public bool ResponseResult = false;
//返回message
        public string ResponseMsg = "failed";

        private string GetJson(T Data)
        {
            if (Data is string || Data is StringBuilder)
                return Data.ToString();
            else if (Data is DataTable)
                return JsonConvert.SerializeObject(Data, new DataTableConverter());
            else
                return JsonConvert.SerializeObject(Data);
        }
    }

webapi：

这里是返回DataTable类型

public APIResult<DataTable> GetProductParentType(string PT_Name=null, string PT_Code=null, int PT_ParentID = 0)
        {
            DataTable dt = pt.GetProductParentType(PT_Name, PT_Code,PT_ParentID);
            APIResult<DataTable> result = new APIResult<DataTable>(dt);
            return result;

        }

这里是返回对象类型

public APIResult<Rootobject> Get(int id)
        {
            Rootobject resp=new Rootobject();
            APIResult<Rootobject> api = new APIResult<Rootobject>(resp);

            return api;
        }

前台HTML ：

<div id="gdv_ProductParentType"></div>


    <script>
        
        $('#gdv_ProductParentType').datagrid({
            url: '../api/BindData/GetProductParentType',
            method: 'get', //默认是post,不允许对静态文件访问
            width: '700',
            rownumbers: true,
            columns: [[
                { field: 'PT_Name', title: 'PT_Name' },
                { field: 'PT_CreateTime', title: 'PT_CreateTime',
                    formatter: function (value, row, index) {
                        var dt = new Date(value);
                        return dt.toLocaleDateString();//设置时间格式
                    }
                }
            ]],
            onClickRow: function (index, row) {
                
            },
            singleSelect: true,
            selectOnCheck: true
        });
        
    </script>
