url(r'^hello/.*$', views.ReadImg.as_view()),
]
创建视图
#coding=utf-8
from django.http import HttpResponse, Http404, FileResponse
from django.views import View
import jsonpickle
class ReadImg(View):
def get(self,request,*args,**kwargs):
import re
filepath = request.path
m = re.match(r'^/hello/(.*)$',filepath)
path = m.group(1)
import os
filedirs = os.path.join(os.getcwd(),'static/imgs',path)
print filedirs
if not os.path.exists(filedirs):
raise Http404()
response = FileResponse(open(filedirs,'rb'),content_type='image/png')
return response
-
settings.py文件中设置
STATIC_URL = '/static/'
STATICFILES_DIRS = [
os.path.join(BASE_DIR,'static/imgs'),
os.path.join(BASE_DIR,'static/css'),
os.path.join(BASE_DIR,'static/js'),
]
配置URL
from django.conf.urls import url
from django.contrib import admin
import views
urlpatterns = [
url(r'^admin/', admin.site.urls),
url(r'^index.html$',views.index_view)
]
创建视图
def index_view(request):
return render(request,'index.html')
创建模板
{% load staticfiles %}
<!DOCTYPE html>
<html lang="en">
