我看Laravel Admin导出csv或者excel的方法里面调用了exit，这个兼容不了。当调用exit时，swoole会抛出一个ExitException，就会走Laravel的异常处理逻辑了，这个还真不好处理。

前面的sql报错是因为数据量大吗？你的数据量有多大呢？提供给我模拟测试看看。

[wilbur-yu]

嗯, 数据量也不是特别大, 18588条吧. 是两个一对一关联表

提个实现的意见. 部分功能如果无法兼容. 可以考虑写个转发黑名单.
名单内的api请求. 转发fpm处理. 这样可以最大程度进行适配,

[huang-yi]

@iblues 很好的建议，不过目前还不会计划在Shadowfax里面添加这个功能，可自行使用nginx实现这个功能。

之前也有研究过，写了一个兼容扩展，可以参考试试：
