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
from django.http import StreamingHttpResponse
def file_down(request):
file=open('/home/amarsoft/download/example.tar.gz','rb')
response =StreamingHttpResponse(file)
response['Content-Type']='application/octet-stream'
response['Content-Disposition']='attachment;filename="example.tar.gz"'
return response 方法三:使用FileResponse
from django.http import FileResponse
def file_down(request):
file=open('/home/amarsoft/download/example.tar.gz','rb')
response =FileResponse(file)
response['Content-Type']='application/octet-stream'
response['Content-Disposition']='attachment;filename="example.tar.gz"'
return response
总结:对比
虽然使用这三种方式都能实现,但是推荐用FileResponse,
在FileResponse中使用了缓存,更加节省资源。 虽说是三种方式,但是原理相同,说白了就是一种方式。
