Django动态下载文件

时间:2022-03-13 12:16:59

前台提交查询条件,下载符合条件的EXCEL数据文件,后端视图中使用 xlwt 库来返回,如:

objs = Units.objects.all()
# 创建 Workbook 时,如果需要写入中文,请使用 utf-8 编码,默认是 unicode 编码。
wb = xlwt.Workbook(encoding='utf-8')
ws = wb.add_sheet('配件价格')
ws.write(0, 0, '配件编号')
ws.write(0, 1, '配件名称')
ws.write(0, 2, '配件价格')
ws.write(0, 3, '商场')
excel_row = 1
for obj in objs:
ws.write(excel_row, 0, obj.unitid)
ws.write(excel_row, 1, obj.unitname)
ws.write(excel_row, 2, obj.price)
ws.write(excel_row, 3, obj.marketid)
excel_row = excel_row + 1
# ------ 开始:这段代码可以用下面注释段替代,都是本应保存为文件格式的改成保存为数据流,以便返回前端下载
response = HttpResponse(content_type='application/vnd.ms-excel')
response['Content-Disposition'] = 'attachment; filename=example.xls'
wb.save(response)
return response
# ------ 结束
"""
sio = StringIO.StringIO()
wb.save(sio)
response = HttpResponse(sio.getvalue(),content_type='application/vnd.ms-excel')
response['Content-Disposition'] = 'attachment; filename=test.xls'
return response
