创建网站
打开宝塔Linux面板，在wordpress网站根目录创建一个api文件夹用来存放自己编写的接口，在api文件夹中新建一个randomimg-api文件夹用来存放随机图片的代码文件。或者也可以直接创建一个新的站点。
具体实现
index.php
代码语言：javascript复制<?php
//获取图片地址文件的绝对路径
$path = dirname(__FILE__);
$file = file($path."/imgurl.txt");
//随机读取一行
$arr = mt_rand( 0, count( $file ) - 1 );
$imgpath = trim($file[$arr]);
//编码判断，用于输出相应的响应头部编码
if (isset($_GET['charset']) && !empty($_GET['charset'])) {
$charset = $_GET['charset'];
if (strcasecmp($charset,"gbk") == 0 ) {
$imgpath = mb_convert_encoding($imgpath,'gbk', 'utf-8');
}
} else {
$charset = 'utf-8';
}
header("Content-Type: text/html; charset=$charset");
die(header("Location: $imgpath"));
?>爬取图片

]运行之后，爬完图片资源地址，将url放入imgurl.txt即可。
我总共爬了两千多张壁纸，应该是完全够了。
访问接口，我的是随机图片api
大概是这样的效果。
补充
下载下来的图片貌似有点小有点糊，因为下下来的的是这个站点的预览缩略图，所以我们需要在imgurl.txt里面改下尺寸。
将540全部修改为2160，960全部修改为2560即可。

效果展示，这是api调用的图片
