方法一:使用HttpResponse
from django.shortcuts import HttpResponse
def file_down(request):
file=open(\'/home/xxx/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/xxx/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/xxx/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。
