123pan解析接口PHP版

jsxyhxz

之前找解析，发现有贴友做了一个php版网页解析123盘：https://www.52pojie.cn/forum.php?mod=viewthread&tid=1790540&highlight=%CD%F8%C5%CC%BD%E2%CE%F6

在此基础上改成接口版本，可以直接调用，测试：https://www.htuzi.com/123pan/123pan.php?url=https://www.123865.com/s/U2ReVv-n3M7

这个好像得把代码放到服务器上，

schoolyears

好东西。

呱呱生

如果php代码是你写的，那就牛啊

pw0n

看着牛逼

pandaligx

会失效么
