这是我在copy-acct-to-home-server中部署的代码段。基本上检查用户名是否带有“ @”符号...如果是,则从比较NAS-IP-Address的mysql表中提取寻线组。最后,如果查询的结果不为null,则它将更新Proxy-to-Realm。
if(request:User-Name =~ /@/){
update control {
SQLQueryResult := "%{sql:SELECT `groupname` FROM `radhuntgroup` WHERE nasipaddress='%{NAS-IP-Address}'}" }
if( %{control:SQLQueryResult} != '') {
update control {
Proxy-To-Realm := SQLQueryResult } }
}
此代码无法正常运行。这是在正确和错误条件下的调试消息摘要结果
从数据库中提取某些值时,应该为代理到领域分配适当的值(但它不起作用)

(6) } # update control = noop
(6) } # if ( %{control:SQLQueryResult} != '') = noop
(6) } # if (request:User-Name =~ /@/) = noop

从日志中可以看出,即使两个if条件都为真(用户名包含@并且SQLQueryResult不为null),也不会使用从数据库获取的值来更新proxy-to-realm属性。
即使没有从数据库中获取的值,条件也似乎为真。这是日志片段。

奇怪的是,尽管它没有从数据库中获取任何值 如果条件(SQLQueryResult!='')在这种情况下应该为假,则第二个条件被评估为true。
SQLQueryResult属性已在字典中定义为字符串。
我不确定我在这里缺少什么...似乎是直接的逻辑。向专家寻求帮助。
答案 0 :(得分:0)
这里有几个问题。
首先,各节的右括号应始终换行。配置解析器不是很好,这可能会使它崩溃。
第二,您要混合使用属性引用和扩展语法。
if( %{control:SQLQueryResult} != '') {
以上无效。老实说,我很惊讶表达式解析器没有抛出错误。可能是因为%{control:SQLQueryResult}
中没有空格,所以将其视为字符串文字,然后将字符串文字与空字符串进行比较。
您要么需要用双引号将扩展名引起来
if ("%{control:SQLQueryResult}" != '') {
或使用属性参考表
if (&control:SQLQueryResult != '') {
我相当确定这就是导致您出现问题的原因。
