[在浏览器中下载excel || Django

Question

def excel(request):
    ans = request.POST.getlist('ans[]')
    ans_final=[]
    rows = request.POST.get('rows')
    for each_ele in ans:
        each_ele = each_ele.split('.')
        each_ele[0] = each_ele[0][:-2]
        each_ele[1] = each_ele[1][:-2]
    fin = each_ele[0]+' - '+each_ele[1]
    ans_final.append(fin)
    workbook = xlsxwriter.Workbook('/home/Desktop/status.xlsx')
    worksheet = workbook.add_worksheet('Test_Data')
    bold = workbook.add_format({'bold': True})
    for i in range(len(ans_final)):
        worksheet.write(0, i,ans_final[i],bold)

    row_index=1
    row_count = int(rows)
    while(row_count):
        col_index=0
        for each_ele in ans:
            worksheet.write(row_index, col_index, eval(each_ele))
            col_index += 1
        row_index += 1
        row_count -= 1


   workbook.close() 
   return JsonResponse({'ok':'ok'})

如在我的views.py中的上述功能中所见，当在UI中单击按钮（Download Excel）时，请求被发送到此功能，并且我正在生成一个excel并保存暂时放在desktop folder中。

当单击“ 下载excel”按钮而不是将其保存在特定路径时，如何在用户界面的浏览器中为用户下载此excel。

Note：-我正在使用xlswriter模块生成Excel。

将工作簿写入BytesIO，然后返回数据作为响应：

from io import BytesIO
# ...
output = BytesIO()
workbook = xlsxwriter.Workbook(output)
# ...
workbook.close()
return HttpResponse(
  output.getvalue(), 
  content_type='application/vnd.openxmlformats-officedocument.spreadsheetml.sheet',
  headers={'Content-disposition': 'attachment; filename=status.xlsx'},
)
