前言

EasyBe终于差不多可以收尾了，EasyBe希望大家多多star和issue；

其实还可以稍微优化下，比如将缓存时间也作为配置来；

functions.php

/**
*主题配置
*/
function themeConfig() {
   // 设置gravatar的镜像服务器
   $gravatarPrefix = new Typecho_Widget_Helper_Form_Element_Radio('gravatarPrefix', array(
        'https://gravatar.loli.net/avatar/' => 'LOLI镜像 <small>https://gravatar.loli.net</small>',
        'https://gravatar.cat.net/avatar/' => 'CAT镜像 <small>https://gravatar.cat.net</small>',
        'https://sdn.geekzu.org/avatar/' => '极客镜像 <small>https://sdn.geekzu.org</small>',
        'https://dn-qiniu-avatar.qbox.me/avatar/' => '七牛镜像 <small>https://dn-qiniu-avatar.qbox.me</small>',
        ),
        'https://gravatar.loli.net/avatar/', _t('Gravatar镜像'), _t('Gravatar镜像服务器'));
    $form->addInput($gravatarPrefix->multiMode());
    // 设置加盐参数
    $salt = new Typecho_Widget_Helper_Form_Element_Text('salt', NULL, 'easybe', _t('加密参数'), _t('头像加密参数建议修改'));
    $form->addInput($salt);

}


/**

 * @return string 返回头像链接
 */
function getAvatar(string $email) {
        $options = Helper::options();
        // 默认缓存15天
        $time = 1296000;
        $gravatarUrl = $options->gravatarPrefix.md5(strtolower(trim($email))).'?s=100&r=G';
        $qqNumber = preg_match('/@qq.com/', $email) ?  explode('@', $email)[0] : '';
        $fileUrl = $qqNumber ? "https://q.qlogo.cn/headimg_dl?dst_uin={$qqNumber}&spec=100&img_type=jpg" : $gravatarUrl;
        $filePath = '/usr/uploads/avatar/'.md5(strtolower(trim($email.$options->salt))).'.jpg';
        $fileInfo = __TYPECHO_ROOT_DIR__.$filePath;
