关于文章头图调用随机图api 方法在根目录下创建一个 PHP 文件:/xxx/img.php,并将本文章末尾附带代码复制保存。打开/usr/themes/handsome/libs/Content.php文件,并搜索whenSwitchHeaderImgSrc字段注释掉$randomNum = unserialize(INDEX_IMAGE_ARRAY);和$random = THEME_URL . 'usr/img/sj/' .@$randomNum[$index] . '.jpg';添加一行$random = '/xxx/img.php?_='.rand(999, 3000);修改后的代码呈以下样子public static function whenSwitchHeaderImgSrc(index=0,howToThumb,attach,content,$thumbField){ $options = mget(); //$randomNum = unserialize(INDEX_IMAGE_ARRAY); // 随机缩略图路径 //$random = THEME_URL . 'usr/img/sj/' . @$randomNum[$index] . '.jpg';//如果有文章置顶，这里可能会导致 index not undefined $random = '/xxx/img.php?_='.rand(999, 3000); $pattern = '/\<img src="true">]*>/i';代码中的 /xxx/img.php 请记得修改成自己实际情况其他文件配置根据代码里的样式添加图片list中是图片 idfun中是当前数组的 url 生成函数，在此可修改图片大小。可将 'fun'=> function($id){return "https://i.keaitupian.net/".$id;}中的网址更改成自己喜欢的随机图 api代码<?php /* 直接请求将随机跳转到一个图片 */ $imgArr = []; //https://www.pexels.com/zh-cn/ $imgArr[0] = [ 'list'=>[267371,230477,1115680,838413,235922,1560424,1056251,416160,96938,2194261, 666839,1133957,1269025,1089932,338711,573910,670061,3113124,247431,434090, 1209843,1684187,358312,1536619,96380,164821,373945,1547248,301920,256468, 1653823,59106,556665,461198,376464,321588,3193917,1040157,189349,396547, 3145552,220067,285173,409701,917076,255464,735911,2120016,1162540,], //'fun'=> function($id){return "https://images.pexels.com/photos/{$id}/pexels-photo-{$id}.jpeg?auto=compress&cs=tinysrgb&dpr=1&w=500";} 'fun'=> function($id){return "https://api.mtyqx.cn/api/random.php";} ]; //https://i.keaitupian.net/ // $imgArr[1] = [ // 'list'=>[ // 'up/40/c0/7c/ec2caa4f7b67d2b44a95bece4e7cc040.jpg', // 'up/38/05/17/57ae05cdfe607c1f877a7881ea170538.jpg' // ], // 'fun'=> function($id){return "https://i.keaitupian.net/".$id;} // ]; function oneImg($id=false){ global $imgArr; //求图片总数 // echo $count; //随机选择一个 if($id == false){ $count = 0; foreach($imgArr as $item){ $count += count($item['list']); } $id = rand(0, $count - 1); } //累积下标 $key = 0; foreach($imgArr as $item){ if(isset($item['list'][$id - $key])){ return $item['fun']($item['list'][$id - $key]); }else{ $key += count($item['list']); continue; } } } header('Location: '.oneImg(isset($_GET['id'])?$_GET['id']:false));exit;{message}随机图api自行调用故梦api{/message}{message}每篇文章头图还可通过自定义字段实现{/message}
