django 返回图片

def read_img(request):
"""
: 读取图片
:param request:
:return:
"""
try:
data = request.GET
file_name = data.get("file_name")
imagepath = os.path.join(settings.BASE_DIR, "static/resume/images/{}".format(file_name)) # 图片路径
with open(imagepath, 'rb') as f:
image_data = f.read()
return HttpResponse(image_data, content_type="image/png")
except Exception as e:
print(e)
return HttpResponse(str(e))

首先用OPEN()方法 用'rb'的形式打开, 然后读取数据 image_data = f.read() , 最后返回 一定要声明类型 content_type="image/png"
