【Fastadmin】自定义404页面-编程知识

1.修改config.php

    // 文件路径：application/config.php// 自定义错误码模板'http_exception_template'    =>  [// 定义404错误的模板渲染404 =>  APP_PATH . 'common/view/404/404.html',],

2.需要把debug关闭才能生效

在.env文件中把debug = true，改为debug = false

3.贴一个404页面源码


<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html xmlns="http://www.w3.org/1999/xhtml"><head><meta charset="UTF-8" http-equiv="Content-Type" content="text/html; charset=utf-8" /><title>404-对不起！您访问的页面不存在</title><style type="text/css">.head404{ width:580px; height:234px; margin:50px auto 0 auto; background:url(__CDN__/assets/img/head404.png) no-repeat; }.txtbg404{ width:499px; height:169px; margin:10px auto 0 auto; background:url(__CDN__/assets/img/txtbg404.png) no-repeat;}.txtbg404 .txtbox{ width:390px; position:relative; top:30px; left:60px;color:#eee; font-size:13px;}.txtbg404 .txtbox p {margin:5px 0; line-height:18px;}.txtbg404 .txtbox .paddingbox { padding-top:15px;}.txtbg404 .txtbox p a { color:#eee; text-decoration:none;}.txtbg404 .txtbox p a:hover { color:#FC9D1D; text-decoration:underline;}</style></head><body bgcolor="#494949"><div class="head404"></div><div class="txtbg404"><div class="txtbox"><p>我们深感抱歉，有一些错误发生了...</p></div></div></body></html>

4.页面效果

5.附加一个小鸟+雪花特效
