射手网突然停止下载了，现在看个电影都很费事，还好射手网的接口没有关闭。看了下接口文档，自己用php写了个脚本，可以直接根据影片文件下载匹配的字幕。

把代码方在/usr/local/bin/目录，文件名zimu，并chmod +x /usr/local/bin/zimu，然后这样用：

zimu 电影文件名

就可以自动下载字幕了
可以加参数“debug”, “all”
比如

zimu test.mkv all

则下载全部匹配的字幕

window用户的话，可以保存成zimu.php然后使用

php zimu.php 电影文件名

这样来下载

不多说，直接上代码

#!/usr/bin/env php
