django404，500错误自定义页面：
将
改为
1.修改settings文件
DEBUG = False
ALLOWED_HOSTS = ['127.0.0.1', 'localhost']或者
ALLOWED_HOSTS = ['*']
2.配置urls文件
from django.conf.urls import handler404, handler500
handler404 = "login.views.page_not_found"
（handler404 = "你的app.views.函数名"）
handler500 = "login.views.page_error"
3.在views文件中定义函数page_not_found和page_error
from django.shortcuts import render_to_response
def page_not_found(request):
return render_to_response('404.html')
def page_error(request):
return render_to_response('500.html')
4.在app的templates下建立404.html和500.html文件（文件内就是你自定义的404或者500页面
了）
<!DOCTYPE HTML>
<html>
<head>
<meta charset="UTF-8" />
<meta name="viewport" content="width=device-width, initial-scale=1">
<meta name="robots" content="none" />
<title>404 Not Found</title>
<style>
*{font-family:"Microsoft Yahei";margin:0;font-weight:lighter;text-decoration:none;text-align:center;line-height:2.2em;}
html,body{height:100%;}
h1{font-size:100px;line-height:1em;}
table{100%;height:100%;border:0;}
</style>
</head>
