Raft各阶段的描述node有三个state:follwercandidateleader所有节点一开始是followerstate,如果followers没有收到leader的消息,那么他们可以成为candidate。然后candidate请求其他节点投票(requestvote),nodes将以投票方式回应,如果candidate获得了大多数node的投票它将会成为leader。这个过程就是LeaderElection。现在,对系统的所有更改都要经过leader,每个更改都作为entry添加到节点的日志中。logentry如果还未提交,就不会更新节点的值。要提交entry,节点首先将其复制

SQLI-LABS(Less-8)

Less-8(GET-Blind-BooleanBased-SingleQuotes)打开Less-8页面,可以看到页面中间有一句PleaseinputtheIDasparameterwithnumericvalue,那么先使用ID这个参数通过GET方式传入一个数值。确定注入点注入语句:?id=1。可以看出没有回显查询结果。接着试一下?id=1',发现出错了,但是并不回显错误。根据本关的名字知道SQL语句使用单引号闭合。尝试使用单引号闭合注释看是否成功,注入语句:?id=1'--+接着使用注入语句?id=1'and1=1--+和?id=1'and1=2--+确定是否存在注入点:发现前一条注入语
