解决微信文章图片防盗链

function actionWechatImg()

{

    header('Content-type: image/jpg');

    $url = $_GET['url'];

    $refer = "http://www.qq.com/";

    $opt = [

            'http'=>[

                'header'=>"Referer: " . $refer

            ]

           ];

    $context = stream_context_create($opt);

    $file_contents = file_get_contents($url,false, $context);

    echo $file_contents;

}

调用示例：

<img src="http://xxx.com.cn/wechat-img?url=http%3A%2F%2Fmmbiz.qpic.cn%2Fmmbiz%2F5ddyukqqNUt7ic07NicfAz9u0KrHEibKKMiab2cXA2sIqoj81hRsMZC65DCiaN67FsH2WaXkNOEE0YFLj5OHwIOegIg%2F0%3Fwx_fmt%3Djpeg">

其实就是模拟来源站点。
