使用Gravatar的HTTPS（适用于任何主题）：

在主题目录中，找到并打开 functions.php 文件，把以下代码复制放到该文件中：

| 1 2 3 4 5 | function mywp_get_https_avatar($avatar) { $avatar = preg_replace('/.*\/avatar\/(.*)\?.*avatar\-([\d]+).*/','<img src="https://secure.gravatar.com/avatar/$1?s=$2" class="avatar avatar-$2" height="$2" width="$2">',$avatar); return $avatar; } add_filter('get_avatar', 'mywp_get_https_avatar'); | | ------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
