Freeradius 3.0.20 重播 rlm_rest 响应

Question

我尝试以简单字符串（回复消息）的形式回复用户的休息响应。针对休息 api 的身份验证有效，我得到一个 json 格式的响应（称为 "token"）。我已将此属性声明为 raddb/dictionary 文件中的一个属性。

我的问题是：如何在身份验证或 post-身份验证部分访问此属性？

低于我的配置 (raddb/sites-available/default)：

authenticate {
    #
    # REST authentication
    Auth-Type rest {
        rest {
            updated = 1
        }
        if (updated) {
            %{Token}
            ok
        }
    }

我尝试了所有的可能性 &Token "%{Token}" &rest:Token

查看下面我的调试输出：

这里的问题是默认情况下 JSON 响应中指定的任何属性都会插入到回复列表中。

这可以通过两种方式解决，要么更改您的 JSON blob 以指定列表限定符：

{ 'request:Token': '<token value>' }

或访问回复列表中的属性：

%{reply:Token}
