附件扩展名始终是html

Question

我有一个Django视图，输出这样的pdf：

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

此代码正确生成PDF文件，但下载文件的名称为evaluation.pdf.html。为什么呢？

Answer 1

您忘了设置合适的content_type：

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

阅读the docs了解详情。
