Question

我有以下情况。我正在做一个excel导出。通过在查询字符串中只传递一个ID来使用ng-href时，它工作正常。但是现在我有多个ID要通过，所以我在HTML和$ http.POST中使用ng-click将postData传递给服务器，如下所示。问题是如果我使用ng-click并调用$ http.post，它会获取所需的数据，但它不会创建excel文档。我认为这是因为我没有使用ng-href，但无法弄清楚如何修复它。任何帮助将不胜感激。

HTML：

<div id="transmission-buttons" data-ng-show="resultsReturned">
        <!--<a ng-href="../ExcelDownload/ExcelDownload.aspx?workListID={{selectedExportWorkListID}}" class="btn btn-info pull-right" target="_blank"><span class="glyphicon glyphicon-export"></span>Export to Excel</a>-->
        <a class="btn btn-info pull-right" href="" ng-click="getWorklistExportData($event)" target="_blank"><span class="glyphicon glyphicon-export"></span>Export to Excel</a>
        </div>

Controller.JS：

$scope.getWorklistExportData = function (e) {
    rest.post('../ExcelDownload/ExcelDownload.aspx', $scope.selectedWorkListIDs).success(function (resp) {
        var successResp = resp;
        e.preventDefault();

    }).error(function (resp) {
        var errResp = resp;
    });

}

aspx.cs：

public partial class ExcelDownload_ExcelDownload : System.Web.UI.Page

{

  protected void Page_Load(object sender, EventArgs e)
    {
        var sr = new StreamReader(Request.InputStream);
        var stream = sr.ReadToEnd();
        CreateExcel(stream);
        //CreateExcel(Convert.ToInt32(Request.QueryString["workListID"]));
        //CreateExcel(823);
    }

}

    private void CreateExcel(string cbrIdList)
{
    var client = new RestClient(ConfigurationManager.AppSettings["TIBCOServer"]);

    string url = ConfigurationManager.AppSettings["ExportWorklistCBRS"];
    //url = url.Replace("{workListID}", workListID.ToString());

    var request = CreateStandardRestRequest(url, Method.POST);

    request.RootElement = "WorkListDetailExport";
    request.AddParameter("CBR_ID", cbrIdList, ParameterType.RequestBody);


    var queryResult = client.Execute<List<CBRSRecord>>(request);
    var queryResult2 = client.Execute(request);

    DataTable tbl = ToDataTable<CBRSRecord>(queryResult.Data);

    tbl = FormatColumnNames(tbl);
    // DataTable tbl = new DataTable();

    using (ExcelPackage pck = new ExcelPackage())
    {
        //Create the worksheet
        ExcelWorksheet ws = pck.Workbook.Worksheets.Add("Worklist");

        //Load the datatable into the sheet, starting from cell A1. Print the column names on row 1
        ws.Cells["A1"].LoadFromDataTable(tbl, true);

        for (int x = 1; x < 50; x++)
        {
            ws.Column(x).AutoFit();
        }
        using (ExcelRange rng = ws.Cells["A1:AB1"])
        {
            rng.Style.Font.Bold = true;
        }

        //Write it back to the client
        Response.ContentType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet";
        Response.AddHeader("content-disposition", "attachment;  filename=WorkList" + DateTime.Now.ToLongTimeString() + ".xlsx");
        Response.BinaryWrite(pck.GetAsByteArray());
        Response.End();
    }
}
