Using rest with sending post request

[Çağlar Karahan]

Dear all,

I want to use the rest module to send post authentication to the server.
Related config files are shown below.

*default: *
authorize {
    if ("%{Service-Type}" == "Login") {
        if (&Message-Authenticator) {
            rest
        }
     }
}

*rest:*
rest {
    connect_uri = "https://127.0.0.1:4433/"
    tls {
      client_cert        = /path/to/client/cert.pem
      client_key         = /path/to/client/key.key
      disable_verify_peer = yes
      check_cert = no
      check_cert_cn = no
    }
    authorize  {
      uri = "${..connect_uri}api/v1/login"
      method = 'post'
      body = 'json'
      tls = ${..tls}
      data = '{"user": {"name":"%{User-Name}", "passwd":
"%{User-Password}"}, "attributes": {"messageAuthenticator":
"%{Message-Authenticator}", "clientIP":"%{Packet-Src-IP-Address}"}}'
      header = 'Content-Type: application/json'
      connect_timeout = 30
      recv_timeout = 30
    }
}

To test it I am using radclient with below command:
echo "Service-Type=1, User-Name=caglar,User-Password=caglar,
Message-Authenticator=0x00" | ./radclient -s -x -P udp a.b.c.d:1812 auth
shared_secret

When running freeradius in debug mode, I am seeing that below error:

*(0) rest: ERROR: Request failed: 56 - Failure when receiving data from the
peer(0) rest: ERROR: Server returned no data*

I am also testing server with curl command. And it works properly.
curl -v -k -H 'Content-Type: application/json'  -d '{ "user": {
"passwd":"caglar", "name":"caglar"},  "attributes": {
"messageAuthenticator":"0x00", "clientIp": "a.b.c.d"}}' -X POST
https://127.0.0.1:4433/api/v1/login --cert /path/to/client/cert.pem --key
/path/to/client/key.key

Thanks for your support,
Caglar
