Typecho评论添加QQ头像及名称

自定义评论样式
官方教程，我是基于里面的改的，修改时注意备份。

获取QQ号

我把昵称输入框修改了下，改了type属性为number,添加min属性为10001,避免填写过低的号码。

<input type="number" name="author" id="author" class="text" min="10001" value="<?php $this->remember('author'); ?>" required placeholder="QQ"/>

功能代码

<?php

header("content-Type: text/html; charset=Utf-8");  

//获取QQ昵称QQ头像
if ($_GET['qq']) {
    $qq = $_GET['qq'];
    //向接口发起请求获取json数据
    $get_info = file_get_contents('https://r.qzone.qq.com/fcg-bin/cgi_get_portrait.fcg?uins='.$qq);
    //转换编码
    $get_info = mb_convert_encoding($get_info, "UTF-8", "GBK");

    //对获取的json数据进行截取并解析成数组
    $name = json_decode(substr($get_info,17,-1),true);

    if($name and $qq){
        $txUrl = 'https://q.qlogo.cn/headimg_dl?dst_uin='.$qq.'&spec=100';
        $arr = array(
            'code' => 1,
            'msg' => 'Success',
            'txUrl' => $txUrl,
            'name' => urlencode($name[$qq][6])
        );
      exit(stripslashes(urldecode(json_encode($arr))));
     }else{
    $arr = array(
        'code' => -1,
        'msg' => 'Error'
    );
    exit(stripslashes(urldecode(json_encode($arr))));
    }
}

?>

具体代码

<?php function threadedComments($comments, $options) {
    
    $qq =  $comments->author;//因为前面我们设置了输入QQ号，所以这里的评论者名称就是填的QQ号
    
    $get_info = file_get_contents('https://r.qzone.qq.com/fcg-bin/cgi_get_portrait.fcg?uins='.$qq);//获取QQ信息
    
    //转换编码
    $get_info = mb_convert_encoding($get_info, "UTF-8", "GBK");

    //对获取的json数据进行截取并解析成数组
    $name = json_decode(substr($get_info,17,-1),true);

    //判断是否为空
    if($name and $qq){
        $txUrl = 'https://q.qlogo.cn/headimg_dl?dst_uin='.$qq.'&spec=40';//QQ头像，可以直接用这个链接加QQ号即可，后面的spec参数为尺寸，后面会放上各个尺寸的参数
        $arr = array(
            'code' => 1,
            'msg' => 'Success',
            'txUrl' => $txUrl,
            'name' => urlencode($name[$qq][6])
        );//name为QQ昵称
         }else{
            $arr = array(
                'code' => -1,
                'msg' => 'Error'
            );
    }
    
    
    $commentClass = '';
    $author = 0;//用户判断是否为博主
    if ($comments->authorId) {
        if ($comments->authorId == $comments->ownerId) {
            $commentClass .= ' comment-by-author';
            $author = 1;//是赋值1
        } else {
            $commentClass .= ' comment-by-user';
        }
    }
 
    $commentLevelClass = $comments->levels > 0 ? ' comment-child' : ' comment-parent';
