无需插件wordpress生成静态缓存文件的方法

说起wordpress生成静态缓存的话首先想到的就是WP Super Cache插件，确实如此，大多数的wordpress站长们都在使用. 但是永远都有那些纠结完美派的人，不喜欢用插件的人也十分的多，而今天介绍的非插件搞定wordpress生成静态缓存文件方法，即可为大家去掉这款强大的wordpress缓存插件WP Super Cache的使用！ 首先说下，WP Super Cache的工作原理吧，该插件的Mod_rewrite加速模式加速效果非常好，因为这种模式是直接将网站的页面生成静态的html页面，然后使用Mod_rewrite将请求转发到静态文件，这样就跳过了php解析这一步直接将页面吐出到浏览器，从而达到加速的效果。 而今天介绍的教程，几乎和上面的工作原理相同，再配合CDN等加速类的使用的话，效果将十分的明显，提速100%啊！ 操作教程 <div style='margin: 8px 0px 1.1em; padding: 0px 0px 5px; outline: none; line-height: normal; border: 1px solid rgb(165, 165, 248); background-image: initial; background-position: initial; background-size: initial; background-repeat: initial; background-attachment: initial; background-origin: initial; background-clip: initial; font-variant-numeric: normal; font-variant-east-asian: normal; font-stretch: normal; font-family: "Courier New", monospace; overflow: hidden; width: 686px; word-break: break-all;'>

代码里都有注释，将代码保存为cache.php文件，然后将其放到网站的根目录下，切记，是网站根目录，非wordpress主题的根目录！然后给网站根目录创建个cache文件夹，给予777的写入权限

然后将代码


<div style='margin: 3px auto 0px; padding: 0px 3px; outline: none; line-height: 21.6px; clear: both; border-width: 1px; border-style: solid; border-color: rgb(0, 153, 204); background: rgb(246, 251, 255); overflow: hidden; font-family: tahoma, arial, "Microsoft YaHei";'>
<div style="margin: 0px; padding: 0px; outline: none; float: right; line-height: 25.2px; font-size: 14px;">
复制代码
</div>
代码如下:</div>
<div id="phpcode5" style='margin: 0px auto 3px; padding: 0px 3px; outline: none; line-height: 25.2px; font-size: 14px; clear: both; border-right: 1px solid rgb(0, 153, 204); background: rgb(221, 237, 251); overflow: hidden; border-left: 1px solid rgb(0, 153, 204); word-break: break-all; border-bottom: 1px solid rgb(0, 153, 204); word-wrap: break-word; font-family: tahoma, arial, "Microsoft YaHei";'>
 
require('cache.php');</div>



放到根目录的index.php的<?php之后 
这样，就会自动的在cache文件里生成静态文件了，然后大家可以配合七牛的加速给予cache文件加速，效果将能够有很明显的提速！
