thnkphp5行为扩展html静态缓存
利用钩子thinkphp钩子进行行为扩展。先上本地测试结果
关闭缓存：

使用方法（和thinkphp3.2相似）
'配置值'
'html_cache_on' => false, // 开启静态缓存
'html_cache_time' => 7200, // 全局静态缓存有效期（秒）
'html_file_suffix' => '.shtml', // 设置静态缓存文件后缀
'html_cache_compile_type' => 'file',//缓存存储驱动
'html_cache_rules' => array( // 定义静态缓存规则
// // 定义格式1 数组方式
//'静态地址' => array('静态规则', '有效期', '附加规则'),
//1.任意控制器的任意操作都适用
'*'=>array('{$_SERVER.REQUEST_URI|md5}'),
//2.任意控制器的md5操作
'md5'=>array('{:module}/{:controller}/{:action}_{id|md5}'),
//3.Static控制器的所有操作
'Static:'=>array('{:module}/{:controller}/{:action}',50)//第一个参数是构造的字符串，后面是缓存50秒
//4.Hmtl控制器的md5操作
'Html:md5'=>array('{:module}/{:controller}/{:action}'),
)
);

扩展步骤
-
文件位置：appplication/tags.php(或appplication/index/tags.php)
[ 'app\\index\\behavior\\ReadHtmlCacheBehavior',//可自行修改文件位置 ], 'view_filter' => [ 'app\\index\\behavior\\WriteHtmlCacheBehavior', ], ];
-
添加文件
application/index/behavior/ReadHtmlCacheBehavior.php
application/index/behavior/WriteHtmlCacheBehavior.php
注意：
检查是否修改模板文件改为了app_debug = true
【核心代码】
<?php
namespace app\index\behavior;
/**

// 开启静态缓存
if('GET' === request()->method() && config('html_cache_on')) {
$cacheTime = $this->requireHtmlCache();
if( false !== $cacheTime && $this->checkHTMLCache(HTML_FILE_NAME,$cacheTime)) { //静态页面有效
// 读取静态页面输出
include HTML_FILE_NAME;
exit();

// 'read'=>array('{id},{name}',60,'md5') 必须保证静态规则的唯一性 和 可判断性
// 检测静态规则

小贴士
感谢您为本站写下的评论，您的评论对其它用户来说具有重要的参考价值，所以请认真填写。
- 类似“顶”、“沙发”之类没有营养的文字，对勤劳贡献的楼主来说是令人沮丧的反馈信息。
