1、效果图
2、修改tp异常页面的模板文件（ /thinkphp/tpl/think_exception.tpl ），将文件中的内容全部替换成下面的内容然后保存即可（若发生报错，请注意语言包问题）
<?php
$cdnurl = function_exists('config') ? config('view_replace_str.__CDN__') : '';
$publicurl = function_exists('config') ? config('view_replace_str.__PUBLIC__') : '/';
$debug = function_exists('config') ? config('app_debug') : false; $lang = [
'An error occurred' => '发生错误',
'Home' => '返回主页',
'Feedback' => '反馈错误',
'The page you are looking for is temporarily unavailable' => '你所浏览的页面暂时无法访问',
'You can return to the previous page and try again' => '你可以返回上一页重试，或直接向我们反馈错误报告'
]; $langSet = ''; if (isset($_GET['lang'])) {
$langSet = strtolower($_GET['lang']);
