response['Content-Type'] = 'application/octet-stream'
response['Content-Disposition'] = 'attachment;filename="test.pdf"'
完整代码如下:
from django.http import StreamingHttpResponse
def big_file_download(request):
# do something...
def file_iterator(file_name, chunk_size=512):
with open(file_name) as f:
while True:
c = f.read(chunk_size)
if c:
yield c
else:
break
the_file_name = "big_file.pdf"
response = StreamingHttpResponse(file_iterator(the_file_name))
response['Content-Type'] = 'application/octet-stream'
response['Content-Disposition'] = 'attachment;filename="{0}"'.format(the_file_name)
return response
