- ET和LT模式解决:防止多次触发,导致一直回显
- Location地址不跳转问题:跳转地址必须要完全输入如:https://www.baidu.com
- 跳转地址成功以后进程异常终止:必须更改当前fd的状态,由可写变为可读,或者直接关闭,然后重Epoll里面剔除,由于这是短链接系统,采用直接剔除,没有改变状态,但是进程为什么会退出,这一点还是不清楚
- epoll_ctl(epollfd, EPOLL_CTL_DEL, fd, &ev)出错,就是在剔除文件fd的时候必须先在epoll里面剔除,在close掉,不然会报错,不是有效的一个fd
- 注意,mysql的字段不能出现关键字,如key这些不然无法正常操作,虽然可以建表
- 在操作mysql的时候,对于varchar类型,查找的时候必须要加“”,不然无法正常操作,这是一个小细节,例如:select * from short_connect where short_key = "xianqi"; <<<<<<< HEAD
