[英]FileContentResult not generating file when called from AJAX post
I apologize if this is a little vague, however the issue presenting itself isnt giving too much away. 如果这有点含糊,我深表歉意,但是提出的问题本身并没有给我们太多的余地。 I have been writting an application that uses MigraDoc to generate PDFs.
我一直在编写一个使用MigraDoc生成PDF的应用程序。 The controller method used to generate and download the PDF is as follows:
用于生成和下载PDF的控制器方法如下:
public FileContentResult ConvertToPDF(int reportTypeId, string cultureName, int headerFooterTemplateId, int baseClassId, string baseTypeName)
{
try
{
string resourcePath = @"C:\TFS\Products\EnGenero\Trunk\EnGenero Application\RiskNetResources\bin\Debug\RiskNetResources.dll"; // --<<-- Reference this
byte[] result = new DocumentWriter().ConvertDocumentToPDFSharp(GetSeedData(reportTypeId, cultureName, resourcePath, headerFooterTemplateId, baseClassId));
return new FileContentResult(result, "application/pdf")
{
FileDownloadName = "MyReportFile.pdf"
};
}
catch (Exception ex)
{
Logger.Instance.LogError("Error in ConvertToPDF", ex);
return new FileContentResult(GetBytes("Error fetching pdf, " + ex.Message + Environment.NewLine + ex.StackTrace), "text/plain");
}
}
During development this has worked fine and when the above code is hit the PDF downloads through the browser fine. 在开发过程中,此方法运行良好,当单击上述代码时,可以通过浏览器下载PDF。 During development I was calling this controller method directly from a JQuery dialog box with Hard Coded parameters.
在开发过程中,我直接从带有硬编码参数的JQuery对话框中调用此控制器方法。
However, I further developed the application and now call this action method through an Ajax Post in a partial view. 但是,我进一步开发了该应用程序,现在通过Ajax Post在局部视图中调用此操作方法。
function CreateDocumentPDF() {
var baseClassId = @Html.Raw(Json.Encode(ViewData["baseClassId"]));
var baseTypeName = @Html.Raw(Json.Encode(ViewData["baseTypeName"]));
var reportTypeId = $j('#ddlReportType option:selected').attr('Value');
var branchId = $j('#ddlBranch option:selected').attr('Value');
var languageId = $j('#ddlLanguage option:selected').attr('Value');
$j.ajax({
url: appRoot + 'DocumentPDFPrinter/ConvertToPDF',
type: 'post',
data: { 'reportTypeId': reportTypeId, 'cultureName': languageId, 'headerFooterTemplateId': branchId, 'baseClassId': baseClassId, 'baseTypeName': baseTypeName },
success: function (data) {
closeDefaultPopup();
},
failure: function () {
alert("Error Generating PDF.");
}
});
}
The same exact same parameter values are passed and the controller action runs through as expected however now there is no file generated/downloaded. 传递完全相同的相同参数值,并且控制器操作按预期运行,但是现在没有文件生成/下载。
I can only imagine it is something to do with the Ajax post as this is the only difference between it running fine or not from what I can see. 我只能想象这与Ajax帖子有关,因为从我所见,这是它运行正常与否的唯一区别。
This is the response I am getting - looks okay as far as I can see...? 这是我得到的回应-就我所知看起来还不错...? Am I missing anything?
我有什么想念的吗?
So I simply moved away from the AJAX call and instead am now calling: 因此,我只是放弃了AJAX调用,而是现在打电话给:
window.location = appRoot + "DocumentPDFPrinter/ConvertToPDF?reportTypeId=" + reportTypeId + "&cultureName=" + languageId etc...
Which seems to do the job nicely. 这似乎做得很好。
