我一直在尝试进行自定义 Django 管理操作，以允许我convert html page to pdf然后download that pdf，for each object separately if more than once is selected. 由于只有一个请求要发送，我知道只有一个响应。所以我尝试将这些 pdf 文件放入 a 中zip file，然后下载 zip 文件。但我最后看到的是corrupted zip file. 不知道问题出在哪里

admin.py 中的代码

def report_pdf(self, request, queryset):
    from django.template.loader import get_template
    from xhtml2pdf import pisa
    import tempfile
    import zipfile

    with tempfile.SpooledTemporaryFile() as tmp:
            with zipfile.ZipFile(tmp, 'w', zipfile.ZIP_DEFLATED) as archive:
                for item in enumerate(queryset):
                    context = {"transactions": item}
                    template_path = "test-pdf.html"
                    template = get_template(template_path)
                    html = template.render(context)
                    file = open('test.pdf', "w+b")
                    pisaStatus = pisa.CreatePDF(html.encode('utf-8'), dest=file,
                                                encoding='utf-8')
                    file.seek(0)
                    pdf = file.read()
                    print(pdf)
                    file.close()
                    fileNameInZip = f"{item.chp_reference}.zip"
                    archive.writestr(fileNameInZip, pdf)
                tmp.seek(0)
                response = HttpResponse(tmp.read(), content_type='application/x-zip-compressed')
                response['Content-Disposition'] = 'attachment; filename="pdfs.zip"'
                return response
