Django使用HttpResponse返回图片并显示的方法

def my_image(request,news_id):   d = path.dirname(__file__)   #parent_path = path.dirname(d)   print("d="+str(d))   imagepath = path.join(d,"static/show/wordimage/"+str(news_id)+".png")   print("imagepath="+str(imagepath))   image_data = open(imagepath,"rb").read()   return HttpResponse(image_data,content_type="image/png") #注意旧版的资料使用mimetype,现在已经改为content_type 

urlpatterns = [   url(r'^index/$', views.index,name="index"),   url(r'^search/$', views.search,name="search"),   url(r'^science/(?P<news_id>.+)/$', views.science,name="science"),   <strong>url(r'^image/(?P<news_id>.+)/$',views.my_image,name="image"),</strong> ] 

<img src="{% url 'show:image' param.id %}" alt="{{param.id}}"/>
