django 中实现文件下载的3种方式

枫铃3年前 (2021-09-30)Python240

方法一：使用HttpResponse

from django.shortcuts import HttpResponse  
def file_down(request):  
    file=open('/home/amarsoft/download/example.tar.gz','rb')  
    response =HttpResponse(file)  
    response['Content-Type']='application/octet-stream'  
    response['Content-Disposition']='attachment;filename="example.tar.gz"'  
    return response

方法二：使用StreamingHttpResponse
