Get a return value from http.post - angularjs

Question

My question is the following I have this code here:
$http.post("dologin", data).then(function(resposta)
When I give a console.log (response.data) it returns the following:
string(40) "7f9870111b7c032f6203d144c97b8aa5a3e3f0c5"
{"status":"success","type_user":"secretary"}
I need to get the "status" value. Before I was using the following and it worked fine
if (response.data.status === 'success') {
if (answer.data.type_user === 'teacher') {
$ location.path ('teacher_view');
} else if (response.data.type_user === 'candidate') {
$ location.path ('candidate_view');
} else if (answer.data.type_user === 'secretary') {
$ location.path ('secretaria_view');
}
Now it does not work anymore and when I give console.log (response.data.status); it returns undefined
My backend php
public function do_login(){
$this->load->model('LoginM');
$request_body = file_get_contents('php://input');
$data = json_decode($request_body);
$cpf = trim($data->cpf);
$senha = trim($data->senha);
$tipo = trim($data->tipo);
$response = $this->LoginM->do_login($cpf, $senha, $tipo);
if ($response["status"] === "success"){
if ($tipo == 'admin') {
$data = array(
'logged_in' => true,
'cod_user' => $response["cod_user"]
);
$message = array("status"=>"success", "tipo_user"=>"secretaria");
}elseif ($tipo == 'professor') {
$data = array(
'logged_in' => true,
'cod_professor' => $response["cod_professor"]
);
$message = array("status"=>"success", "tipo_user"=>"professor");
}elseif ($tipo == 'candidato') {
$data = array(
'logged_in' => true,
'cod_candidato' => $response["cod_candidato"]
);
$message = array("status"=>"success", "tipo_user"=>"candidato");
}
$this->session->set_userdata($data);
}else{
$message = array("status"=>"error","message"=>"CPF ou senha incorretos");
}
echo json_encode ($message);
}
Test with response from console.log (response.data) and console.log (response.data.status)
Image console.log

Below thing should do the trick:
var state = JSON.parse('{'+res.data.split("{")[1]);
if (state.status === 'success') {
if (state.type_user === 'teacher') {
$ location.path ('teacher_view');
} else if (state.type_user === 'candidate') {
$ location.path ('candidate_view');
} else if (state.type_user === 'secretary') {
$ location.path ('secretaria_view');
}
But, i would strongly suggest you to fix your server response from string which you are getting right now, to the JSON which you were getting earlier
