权限控制(access control lists) 针对节点可以设置相关读写等权限，目的是为了保证数据安全性。 权限permissions 可以指定不同的权限访问以及角色

ACL的构成

zk的acl通过[acheme:id:permissions] 来构成权限列表 acheme 代表采用的某种权限机制 id:允许访问的用户 permissions 权限组合字符串

acheme

world:world下只有一个id,即只有一个anyone用户,那么组合的写法就是world:anyone:[permissions] getAcl:获取某个节点的acl权限 auth 代表认证登录，需要注册用户有权限就可以，形式是 auth:user:password:[permissions] digest: 需要对密码加密才能访问，组合形式 digest:username:BASE64(SHA1(password)):[permissions]

代码语言：javascript复制
[zk: localhost:2181(CONNECTED) 1] getAcl /test
'world,'anyone
: cdrwa

setAcl:设置某个节点的acl权限 addauth:输入认证授权信息，注册是输入明文密码登录，但是在zk的系统里，密码是以加密的形式存在的
