Question

我尝试在Firefox（v.49.0.2）浏览器中保存（CTRL + S）正确显示的PDF文档时，我的客户无法下载PDF文档。我不知道这是我的编程问题还是浏览器问题。我可以下载的唯一方法是点击PDF插件的“下载”按钮，但我的客户想要用（CTRL + S）选项保存文件。请看一下这张照片：

还有一个角度代码，我尝试在浏览器中打开文件：它适用于Chrome和Edge，它还可以在Firefox中打开PDF。响应对象是$ http响应。

function openFile(response) {

        var responseHeaders = response.headers();
        var contentType = responseHeaders['content-type'];
        var contentDisposition = responseHeaders['content-disposition'];
        var fileName = contentDisposition.match(/filename="(.+)"/)[1];
        fileName = fileName.substring(0, fileName.indexOf(';')-1);
        var file = new Blob([response.data], { type: contentType });

        if(contentType==='application/pdf') //YES content-type is PDF
        {
            try
            {
                var fileURL = URL.createObjectURL(file);
                window.open(fileURL);
            }
            catch(err) //For Edge, just save a file
            {
                FileSaver.saveAs(file, fileName);
            }
        }
        else //for other content types, just save a file
        {
            FileSaver.saveAs(file, fileName);
        }
    }

这是我的C＃后端代码：

  byte[] report = service.GetReportCustomerCreditRatesCard();//render report
        RenderFormatResolver renderResolver = new RenderFormatResolver(request.renderFormat);
        HttpContent content = new ByteArrayContent(report);
        var response = new HttpResponseMessage(HttpStatusCode.OK);
        response.Content = content;
        response.Content.Headers.ContentType = new MediaTypeHeaderValue(renderResolver.MIMEType);
        response.Content.Headers.ContentLength = report.Length;
        response.Content.Headers.ContentDisposition = new ContentDispositionHeaderValue("attachment") //"attachment", "inline"
        {
           FileName = String.Format("{0}." + renderResolver.FileNameExtension,                    
Translations.REPORT_FILENAME_CUSTOMER_CARD),
           Name = Translations.REPORT_FILENAME_CUSTOMER_CARD
        };
        return response;

尝试一次更改响应对象中的内容处置标头以保存文件名：

Content-Disposition: attachment; filename="document.pdf"

类似于：

response.Content.Headers.ContentDisposition = new ContentDispositionHeaderValue( 'attachment; filename="document.pdf"' );

这可能会有所帮助。不确定，但值得一试......
