Question

我在我的Home控制器中创建了一个FileResult方法，该方法接受FormCollection并根据输入返回一个文件。该方法可以很好地获取数据，因为在检查Fiddler之后，Image选项将作为图像返回。这是被称为

的控制器方法

public FileResult DownloadReport(FormCollection collection)
{
    byte[] response;
    string fileName = "";
    string contentType = "";
    string startDate = Convert.ToString(collection["hidden-start-date"]);
    string endDate = Convert.ToString(collection["hidden-end-date"]);
    string storeID = Convert.ToString(collection["hidden-store-id"]);
    string reportID = Convert.ToString(collection["hidden-report-id"]);
    string returnType = Convert.ToString(collection["hidden-return-type"]);
    DateTime dateStart = DataConversion.getDateTimeFromStringDateResponse(startDate.ToString());
    DateTime dateEnd = DataConversion.getDateTimeFromStringDateResponse(endDate.ToString());
    if (returnType == "pdf")
    {
        fileName = "report.pdf";
        contentType = "application/pdf";
    }
    if (returnType == "image")
    {
        fileName = "report.tif";
        contentType = "image/tiff";
    }
    if (returnType == "excel")
    {
        fileName = "report.xlsx";
        contentType = "application/vnd.ms-excel";
    }
    if (returnType == "word")
    {
        fileName = "report.docx";
        contentType = "application/msword";
    }

    SynchDB.User returnObject = (SynchDB.User)Session["SessionUserReturnObject"];
    response = SoapServiceController.getExportReportResponse(returnObject.AccountLogin, returnObject.AccountPassword, returnObject.CompanyID, Convert.ToInt64(storeID), 0, returnObject.ID, Convert.ToInt64(reportID), dateStart, dateEnd, returnType);
    Response.AppendHeader("Content-Disposition", "inline; filename=" + fileName);
    return File(response, contentType);
}

调用该方法的表单如下所示，它位于_Layout.cshtml文件中

<form id="form-content-type" method="post" action="@Url.Action("DownloadReport","Home")">
    <input type="hidden" id="hidden-report-id" name="hidden-report-id" />
    <input type="hidden" id="hidden-store-id" name="hidden-store-id" />
    <input type="hidden" id="hidden-start-date" name="hidden-start-date" />
    <input type="hidden" id="hidden-end-date" name="hidden-end-date" />
    <input type="hidden" id="hidden-return-type" name="hidden-return-type" />
</form>

调用该方法的javascript看起来像这样

downloadReport: function () {
    $.mobile.loading('show');
    $('#hidden-report-id').val(storage.readValue('reportID'));
    $('#hidden-store-id').val(storage.readValue('storeID'));
    $('#hidden-start-date').val(storage.readValue('startDate'));
    $('#hidden-end-date').val(storage.readValue('endDate'));
    $('#hidden-return-type').val(storage.readValue('returnType'));

    $('#form-content-type').submit();
}

和

$('#pdf-download-button').click(function () {
                $('#downloadPopup').popup('close');
                storage.storeValue("returnType", "pdf");

                DataAccess.downloadReport();
            })

每次调用该方法时，它都会返回默认视图，该视图是主控制器的默认路径，而不是返回文件。

非常感谢任何帮助，谢谢

MVC4 FileResult返回默认的View而不是file
