虫虫博客在很早之前针对手机客户端做过适配，不过一直用百度的siteapp实现。今天突然发现百度siteapp打开很慢，而且打开后还提示危险。搜索发现网上很多用户和我的情况类似，而且是在2个星期前就已经发生。很多人猜测百度可能已经放弃siteapp项目。我对于百度虽然没有好感，但还是不敢相信他会一点都不通知的就关闭服务。最后我还是决定删掉百度siteapp，就让他去死吧，自己实现移动站的适配。
按照网上教程，稍微做下修改。
第一步：
下载所需文件（下载地址一），解压缩后上传到博客主题的根目录。例如你的博客主题是twentyfifteen，那么主题的根目录类似如下：wp-content/themes/twentyfifteen 。
第二步：
在wordpress后台点击“外观”->“编辑”，选择functions.php模板函数文件编辑。在最后“?>”符号前加入如下代码后保存。

foreach ($mobile_agents as $device) {
if (stristr($user_agent, $device)) {
$is_mobile = true;
break;
}
}
return $is_mobile;
}
/*移动站界面结束*/第三步：
在wordpress后台点击“外观”->“编辑”，选择index.php修改首页文件。在文件最前面添加如下代码。
<?php if( !is_mobile() ){ ?>在文件最后添加如下代码后保存。
<?php } else{ ?>
<?php get_template_part(“indexForMobile”);?>
<?php } ?>还是在外观编辑页面，选择single.php编辑文章内容页文件。和首页一样，在文件最前面添加如下代码。
<?php if( !is_mobile() ){ ?>在最后添加如下代码保存。
<?php } else{ ?>
<?php get_template_part("singleForMobile");?>
<?php } ?>这样首页和文章内容的移动适配页面就做好了，感兴趣的话按照类似思路可以修改其他页面。实际试了下修改后效果还不错，文章分类列表页、翻页等都正常，效果如下图。
最后博主吐槽下，在中国网络环境，免费东西真的很不靠谱。先是360关闭静态资源和字体库，又是关闭网盘。还有即使像百度这样的大公司，对产品对用户的态度也是让人喜欢不起来，无声无息服务就不可用了。
