WebService中使用Aspose.Cells.dll

首先,目前我是在Json里面使用的,然后关于HTML+WebService+Json怎么使用,可以看看Jsonp跨域的相关例子。本次的实现原理是:通过HTML传送参数到WebService,然后在WebService生成Excel文件,然后保存在服务器上,然后服务器返回文件的相对路径,然后HTML接收到路径,直接下载;下面我直接贴出WebService的代码; /// <summary> /// 获取房间每小时报表 /// </summary> [WebMethod(EnableSession = true)] public void GetRoomReportOfHour() { HttpContext.Current.Response.ContentType = "application/json;charset=utf-8"; string jsonCallBackFunName = HttpContext.Current.Request.Params["jsoncallback"].ToString(); //上面代码必须,不能注释 //中间代码执行自己的业务操作,可返回自己的任意信息(多数据类型) string strJson = ""; string Date = HttpContext.Current.Request["Date"]; string DeptID = HttpContext.Current.Request["DeptID"]; string BuildId = HttpContext.Current.Request["BuildId"]; if (!string.IsNullOrWhiteSpace(Date) && !string.IsNullOrWhiteSpace(DeptID) && !string.IsNullOrWhiteSpace(BuildId)) { int iDepartID = DataFormat.ConvertDBNullToInt32(DeptID); DateTime dtTime = DataFormat.ConvertDBNullToDateTime(Date); List<ModelForDepartmentOrRoomOfHour> mList = DataLoader.GetRoomOfHour(dtTime, DeptID, BuildId); if (mList.Count > 0) { string strReportDate = DateTime.Now.ToString("yyyy-MM-dd"); string strDepartName = DataLoader.GetDepartInfoByDepartID(iDepartID).DeptName; string strBuildName = DataLoader.GetBuildInfoByBuildID(BuildId).F_BuildName; DataTable dtSource = DTListFormat.ListToDataTable(mList); //Excel的路径 是放excel模板的路径 WorkbookDesigner designer = new WorkbookDesigner(); string strSystemPath = HttpContext.Current.Server.MapPath("~"); designer.Open(strSystemPath + "/excel/RoomReportOfHour.xls"); Worksheet sheet = designer.Workbook.Worksheets[0]; var c124 = sheet.Cells[1, 24];//第二行 第25列,导出日期 c124.PutValue(strReportDate); var c33 = sheet.Cells[3, 3]; c33.PutValue(strBuildName); var c36 = sheet.Cells[3, 6]; c36.PutValue(strDepartName); var c312 = sheet.Cells[3, 12]; c312.PutValue(Date); sheet.Cells.ImportDataTable(dtSource, false, 6, 0, true); SaveOptions s = new XlsSaveOptions(SaveFormat.Excel97To2003); string str = ""; str = HttpUtility.UrlEncode(string.Format("{0}.xls", DateTime.Now.ToString("yyyyMMddHHmmss")), Encoding.UTF8).ToString(); designer.Workbook.Save(strSystemPath + "/Attachment/" + str);//通过这个方法,就可以通过WebService来使用Excel文件保存和文件下载了。 ModelForReport aReport = new ModelForReport() { strUrl = "Attachment/" + str }; strJson = JsonHelper.Serialize(aReport); } } //下面代码必须,不能注释 HttpContext.Current.Response.Write(string.Format("{0}({1})", jsonCallBackFunName, strJson)); HttpContext.Current.Response.End(); }
HTML端: function fExportReportOfDay() { var date = $("#IdForDayTime").val(); var DepartId = $('#DeptID').combobox('getValue') //获取当前选中的值; var BuildID = $('#BuildID').combobox('getValue') //获取当前选中的值; $.ajax({ type: 'GET', url: vUrlPre + 'WebService.asmx/GetRoomReportOfHour?jsoncallback=?', dataType: 'jsonp', data: { Date: date, DeptID: DepartId, BuildId: BuildID }, success: function(data) { var vUrl = vUrlPre + data.strUrl;//解释一下,vUrlPre是一个全局的参数,是远程WebService的服务地址,例如:http://www.webservice.com/ fDownLoad(vUrl); }, error: function(data) { var vData = JSON.stringify(data); } }) }
