windows可以通过链接下载主题，linux wget得知跳转到https无法认证，需要加参数wget --no-check-certificate  http://wordpress.org/themes/download/moesia.1.09.zip可以下载；或者加上www，在php里面更改如下：（wordpress/wp-admin/update.php的'install-theme' == $action）

$upgrader->install($api->download_link);

改为：

$upgrader->install(str_replace('http://', 'http://www.', $api->download_link));
