Django通过HttpResponse如何返回用户头像

代码示例：

def test(request):
# 获取当前文件的路径、父路径以及下一层的路径
    curr_dir = os.path.dirname(__file__)
    parent_path = os.path.dirname(curr_dir)
    image_path = os.path.join(parent_path,"static/image/timg.jpg")
"""
 D:\Python Work Location\WebRobot\app01
 D:\Python Work Location\WebRobot
 D:\Python Work Location\WebRobot\static/image/back.png
 """
    image_data = open(image_path,"rb").read()

return HttpResponse(image_data,content_type='image/jpg')

效果展示：
