DocumentFormat.openxml似乎不适用于Azure函数

Question

我一直试图在Azure函数中集成openxml包。该代码可以很好地编译，但是当我尝试访问该函数的url时，它不会下载文件，但无法调用，并且代码中没有执行错误。

public static async Task<HttpResponseMessage> Run([HttpTrigger(AuthorizationLevel.Function, "get", "post", Route = null)]HttpRequestMessage req, TraceWriter log, [Inject]TrainingManager trainingManager)
    {

        //dynamic data = await req.Content.ReadAsAsync<object>();
        //string trainingCourseId = data?.trainingCourseId;
        log.Info("Function App Started");
        HttpResponseMessage response = req.CreateResponse(HttpStatusCode.OK);
        using (MemoryStream mem = new MemoryStream())
        {
            // Create Document
            using (WordprocessingDocument wordDocument =
                WordprocessingDocument.Create(mem, WordprocessingDocumentType.Document, true))
            {
                // Add a main document part. 
                MainDocumentPart mainPart = wordDocument.AddMainDocumentPart();

                // Create the document structure and add some text.
                mainPart.Document = new DocumentFormat.OpenXml.Wordprocessing.Document();
                Body docBody = new Body();

                // Add your docx content here
                Paragraph para = docBody.AppendChild(new Paragraph());
                Run run = para.AppendChild(new Run());
                run.AppendChild(new Text("Hi"));

                mainPart.Document.Save();
            }
            mem.Seek(0, SeekOrigin.Begin);
            response.Content = new StreamContent(mem);

        }

        response.Content.Headers.ContentDisposition = new System.Net.Http.Headers.ContentDispositionHeaderValue("attachment")
        {
            FileName = "AttendanceList.docx"
        };
        response.Content.Headers.ContentType = new System.Net.Http.Headers.MediaTypeHeaderValue("application/msword");

        log.Info("Sending Response");
        return response;
    }

让我知道是否有人遇到了这个问题或有解决方案。
