Question

我有一个输出pdf的Django视图，如下所示：

def evaluation_download(request):
    ....

    response = HttpResponse()
    response["mimetype"] = "application/force-download"
    response['Content-Disposition'] = 'attachment; filename="evaluation.pdf"'
    c = canvas.Canvas(response)

    ....  # Draw stuff on canvas

    c.showPage()
    c.save()

    return response

这段代码正确地生成了PDF文件，但下载的文件名为evaluation.pdf.html。为什么？

Answer 1

您忘记设置适当的content_type

response = HttpResponse(content_type='application/pdf')
response['Content-Disposition'] = 'attachment; filename="evaluation.pdf"'
