Jackie在SAE上搭建了博客，起初使用了SAE默认的Wordpress 3.4.1，版本实在太低，作为PHP盲，只好忍了。

后来浏览网站时无心看到了【WordPress SAE修改版】 WordPress on SAE 更新至 4.1，文章中提供了Wordpress 4.1 SAE改进的下载链接，以及升级方法，简单明了，于是Jackie的博客升级为了4.1版本。

前几天，Jackie在查阅资料时，不小心看到了 WordPress静态化插件SAE版, 于是不安分起来，参照文章中介绍的方法折腾了半天，终于搞定了静态化。

博客静态化的操作步骤

从 cos-html-cache插件官网下载插件，当前最新版本为2.7.4。将插件解压，并上传压缩包内的文件上传至wp-content/plugins/cos-html-cache内，目录内的文件布局如下：
```
common.js.phpcos-html-cache.phpcosbeta-zh_CN.mocosbeta-zh_CN.poreadme-chs.txtreadme.txt
```

在插件目录下增加index.php文件，内容如下

<?php define("SUMMETA","<! --this is the first view page created at ".date("Y-m-d H:i:s")." by JackieAtHome index.php -->"); $kv = new SaeKV(); $kv->init(); $sitemap = $kv->get($_SERVER['SCRIPT_URI']."index.html"); if ($sitemap) {    header('Content-type:text/html; charset=utf-8');    echo $sitemap; }else{    echo fetchUrl($_SERVER['SCRIPT_URI']).SUMMETA; } function fetchUrl($url){    $ch=curl_init();    curl_setopt($ch, CURLOPT_AUTOREFERER,0);    curl_setopt($ch, CURLOPT_REFERER, 'staticindex');    curl_setopt($ch, CURLOPT_URL, $url);    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);    $ret=curl_exec($ch);    curl_close($ch);    if ($ret) {        return $ret;    }else{        return false;    }}?>

在插件目录下增加static.php，内容如下

<?php define("SUMMETA","<! --this is the first view page created at ".date("Y-m-d H:i:s")." by JackieAtHome static.php  -->"); $kv = new SaeKV(); $kv->init(); $sitemap = $kv->get($_SERVER['SCRIPT_URI']); if ($sitemap) {    header('Content-type:text/html; charset=utf-8');    echo $sitemap; }else{    echo fetchUrl($_SERVER['SCRIPT_URI']).SUMMETA; } function fetchUrl($url){    $ch=curl_init();    curl_setopt($ch, CURLOPT_AUTOREFERER,0);    curl_setopt($ch, CURLOPT_REFERER, 'static');    curl_setopt($ch, CURLOPT_URL, $url);    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);    $ret=curl_exec($ch);    curl_close($ch);    if ($ret) {        return $ret;    }else{        return false;    }}?>

Copy after login

修改SAE的config.yaml，增加rewrite规则，内容如下

name: app_nameversion: app_versionhandle:  - rewrite:  if ( %{REQ:REFERER} != "static" && %{REQUEST_URI} ~ "html$" ) goto "wp-content/plugins/cos-html-cache/static.php"  - rewrite:  if ( !is_dir() && !is_file()) goto "index.php?%{QUERY_STRING}"  - rewrite:  if ( path ~ "/(\s*)$" && %{REQ:REFERER} != "staticindex" ) goto "wp-content/plugins/cos-html-cache/index.php"

修改cos-html-cache.php，使用SaeKV对象来保存、读取数据，如下是Patch

登录博客后台，在设置-> 固定链接，修改URL格式为 /archives/%post_id%.html，即在末尾增加 .html。
登录博客后台，打开插件页面，找到 cos-html-cache插件，点击启用。

重新刷新首页或者文章页面，查看页面源码，如果页面底部出现如下代码，

<! --this is the first view page created at 2016-04-01 22:35:13 by JackieAtHome index.php -->

Copy after login

或者

<! --this is the first view page created at 2016-04-01 22:35:13 by JackieAtHome static.php -->

Copy after login

恭喜你，博客页面静态化成功。

注意事项

WP-PostViews插件的文章浏览统计特性失效，参考通过Ajax手动解决WordPress WP-PostViews不计数的问题中的方法，在页面前增加如下代码。

<?php if (is_singular()) : ?>    <!-- ajax post view -->    <script type="text/javascript">        $.ajax({            url: "<?php echo get_site_url(). '/wp-admin/admin-ajax.php?>'?>",            data: {                "postviews_id": "<?php the_ID(); ?>",                "action": "postviews",                "_": new Date().getTime()            }        });    </script><?php endif; ?>
