利用通用视图手写底层代码读取

相关代码

urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'^staticread/', include('staticread.urls'))

urlpatterns = [
    # IndexView是自定义的视图处理类，需要继承django.views.View，可以重写get/post方法处理浏览器请求；as_view()是固定写法
    url(r'^$', views.IndexView.as_view()),
    # 原生代码读取静态资源文件
    url(r'^read/.*$', views.ReadImg.as_view()),

Django读取

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

urlpatterns = [
    # IndexView是自定义的视图处理类，需要继承django.views.View，可以重写get/post方法处理浏览器请求；as_view()是固定写法
    url(r'^$', views.IndexView.as_view()),
    # 原生代码读取静态资源文件
    url(r'^read/.*$', views.ReadImg.as_view()),
    url(r'^demo/.*$', views.StaticView.as_view()),
]
