Answer 1

from django.http import HttpResponse
f = open('d:/a.jpg', 'rb')
response = HttpResponse(f.read(), content_type='image/jpeg')

针对大的文件需要chunk的话可以使用FileReponse:

from django.http import FileResponse
response = FileResponse(open('d:/a.jpg', 'rb'), content_type='image/jpeg')

Answer 2

HttpResponse的实例response对象是个类python字典类型的，你可以这样设置他的头属性：
response = HttpResponse(...)
response['Content-type'] = 'image/jpeg'
