@lhbc curl 请求没有返回

@weijancc 不是

找到问题了。。。服务端在报错，只看了客户端日志。。。

@weijancc 大佬 是运营商会拦截么？

@elechi 有的，这是被防火墙拦截了？

我也有这种情况，啥都没按，自己叮叮叮地响

@SKYNE 可以了 谢谢

ddos 攻击；
sql 语句性能太差；
redis 持久化把盘写满了；
机房网络故障；


有人问线上出问题如何不登录线上服务器而快速定位问题，这个大佬们知道吗？

抹掉不会，重装系统会

阳了也在办公，但还是按病假算，垃圾公司，还要兼职前台 清洁工，绩效扣起来就跟玩儿一样，还突然通知你去 30 公里外上班，说距离差不多

清洁工，前台也可以由程序员兼做




敢报公司名称么

@0x2CA 是的
@hxsf 好的 我试试 谢谢
@guoziyan vim 也很卡
