Django 返回文件流

实现如下：

from django.http import HttpResponse


@csrf_exempt
def get_file(request):
	"""
	获取文件
	:param request:
	:return:
	"""
	try:
		book_id = request.GET.get("id")
		file_name = BookInfo.objects.filter(id=book_id).values()
		if file_name.count() == 0:
			return HttpResponse(False)
		file_path = "/opt/" + file_name
		with open(file_path, 'rb') as f:
			response = HttpResponse(f.read(), content_type="application/pdf", charset="utf-8")
			response['Content-Dispositon'] = "attachment; filename={0}".format(file_name)
			response["Access-Control-Allow-Origin"] = '*'
			response["Server"] = '*'
			return response
	except KeyError:
		return HttpResponse(False)
			

content_type=“application/pdf” 不仅是pdf,也可以是content_type="application/doc"等等文件类型
