第三百九十一节，Django+Xadmin打造上线标准的在线教育平台—404，403，500页面配置
路由映射
在全局也就是根目录里的urls.py里配置404路由映射
注意：不是写在urlpatterns列表里，而是独立写
handler404 = '404逻辑函数'
函数需要从app路径开始
# 全局404页面配置
handler404 = 'app_users.views.pzhi404'
逻辑函数
可以写在任意一个app的views.py文件里
render_to_response('设置要显示的404页面', {})
def pzhi404(request):
from django.shortcuts import render_to_response
response = render_to_response('404.html', {})
response.status_code = 404 # 状态码404
return response
404html里静态文件配置
<!DOCTYPE html>
<html>
{% load staticfiles %} {# 启用静态文件引用#}
<head>
<meta charset="UTF-8">
<title>404</title>
<link rel="stylesheet" type="text/css" href="{% static 'css/reset.css'%}">
<link rel="stylesheet" type="text/css" href="{% static 'css/animate.css'%}">
<link rel="stylesheet" type="text/css" href="{% static 'css/style.css'%}">
<script type="text/javascript" src="{% static 'js/jquery.min.js'%}"></script>
</head>
<body class="bg404 errorpage">
<section>
<div class="wp">
<div class="cont">
<img src="{% static 'images/pic404.png'%}"/>
<br/><br/><br/><br/>
<p>wow~这个页面被外星人抢走了~</p>
<br/>
<span>Wow~ this page was the alien took ~</span>
</div>
</div>
</section>
</body>
</html>
配置settings.py文件
注意：如果要设置404页面显示，就必须在settings.py文件关闭调试模式
# SECURITY WARNING: don't run with debug turned on in production!
DEBUG = False # 将调试模式关闭,关闭后访问页面出错不会显示错误(大黄页)
ALLOWED_HOSTS = ['*'] # 当关闭调试模式时，必须设置允许访问的ip，*代表所有以访问
当关闭了调试模式时，就必须给静态文件做url路由映射
settings.py
STATIC_URL = '/static/' # 设置静态文件前缀名称
# 配置静态文件目录
STATICFILES_DIRS = [
os.path.join(BASE_DIR, 'static'), # 设置静态文件路径
]
# 配置静态文件访问路径
STATIC_ROOT = os.path.join(BASE_DIR, 'static') # 设置上传文件路径
urls.py
from django.conf.urls import url, include # 导入django自在的include逻辑
from django.contrib import admin
from django.views.generic import TemplateView # 导入django自带的TemplateView逻辑
from django.views.static import serve # 导入django自带的serve静态资源逻辑
import xadmin # 导入xadmin from app_users.views import deng_lu, zhu_ce, active_code, logout # 导入登录逻辑处理类
from app_organization.views import org_list, course_comment,usercenter_info,touxiang # 导入授课机构逻辑
from MxOnline.settings import MEDIA_ROOT, STATIC_ROOT urlpatterns = [
url(r'^xadmin/', xadmin.site.urls), url(r'^index.html', TemplateView.as_view(template_name='index.html'), name='index'), # 注册
url(r'^register.html', zhu_ce.as_view(), name='register'),
url(r'^captcha/', include('captcha.urls'), name='captcha'),
url(r'^active/(?P<active_de>.*)/$', active_code.as_view(), name="user_active"), # 登录
url(r'^login.html', TemplateView.as_view(template_name='login.html'), name='login'),
url(r'^deng_lu', deng_lu.as_view(), name='deng_lu'),
url(r'^logout', logout.as_view(), name='deng_lu'), # 授课机构
url(r'^org_list.html', org_list.as_view(), name='org_list'), # 专门处理静态资源请求映射，也就是media上传文件夹里的请求映射
url(r'media/(?P<path>.*)$', serve, {'document_root': MEDIA_ROOT}), # 配置静态文件访问
url(r'static/(?P<path>.*)$', serve, {'document_root': STATIC_ROOT}), url(r'course_comment.html', course_comment.as_view(), name='course_comment'),
url(r'usercenter_info.html', usercenter_info.as_view(), name='usercenter_info'), # 上传头像
url(r'touxiang/', touxiang.as_view(), name='touxiang')
] # 全局404页面配置
handler404 = 'app_users.views.pzhi404'
其他如500页面配置同理
url映射
# 全局404页面配置
handler404 = 'app_users.views.pzhi404'
# 全局500页面配置
handler500 = 'app_users.views.pzhi500'
逻辑
def pzhi404(request):
from django.shortcuts import render_to_response
response = render_to_response('404.html', {})
response.status_code = 404
return response def pzhi500(request):
from django.shortcuts import render_to_response
response = render_to_response('500.html', {})
response.status_code = 500
return response
