新浪图片外链失效解决方案

这里提供一种临时处理的思路:既然新浪判断了Referer,我们伪造就是了

最后用API方式调用,例如:api.php?url=新浪外链地址
解决方案

API接口

<?php
/**
 * @description: curl_get 获取远程图片
 * @param  图片url
 * @return: 获取到的图片文件流

{
    $ch = curl_init($url);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

    $content = curl_exec($ch);
    curl_close($ch);
