FreeRadius与REST API集成时认证失败的问题求助

大家好，我正在尝试把FreeRadius集成到我们的平台里，通过平台的REST API来实现认证功能。目前FreeRadius服务器和REST API都跑在Docker容器里，用docker-compose关联起来了。

经过反复调试，现在FreeRadius已经能成功调用REST服务，我也能看到API返回了正确的响应，但就算用已知的有效凭证，认证还是失败了。

我的配置如下： #

sites-enabled/default 中的授权与认证段

authorize {

# Use REST API for authorization if we have a password

if (&User-Password) {

update control {

Auth-Type := 'rest'

}

}

}

authenticate {

rest

}

mods-enabled/rest 文件配置

connect_uri = "http://freeradiusapi:8080/"

authorize {

uri = "${..connect_uri}check/%{User-Name}"

method = 'get'

}

authenticate {

uri = "${..connect_uri}auth/%{User-Name}/%{User-Password}"

method = 'get'

}

API确实被正确调用了，而且返回了HTTP 200状态码，下面是日志的关键片段：

今天早些时候我确实让它正常工作过，但现在实在找不到哪里出问题了，希望大家能给我一些思路，非常感谢！
