ionic v3 angular v5 cant pass CSRF to php Slim server - php

Question

I have made PHP Slim server. Authentication for it and CSRF.
I want to use it as a REST Server.
I have a created an App using IonicFramework which uses Angular.
I want to authenticate myself with this code
let hheaders:Headers=new Headers();
hheaders.append('Access-Control-Allow-Origin' , '*');
hheaders.append('Access-Control-Allow-Methods', 'POST, GET, OPTIONS, PUT');
hheaders.append('Accept','application/json');
let options = new RequestOptions({ headers:hheaders});
let data = new FormData();
data.append("email", this.myForm.email);
data.append("password", this.myForm.password);
data.append("csrf_name", this.myForm.csrf_name);
data.append("csrf_value", this.myForm.csrf_value);
return this.http.post('http://10.1.3.101:8088/public/auth/signinservice',data,this.options)
.map(res => res.json())
.toPromise();
But I always get Failed CSRF check! I do not know what is the problem. At this point the Slim Server is basic. It is very simple and similar to this Github project with new methods in AuthController.php
like
public function getSignInService($request, $response){
$nameKey = $this->csrf->getTokenNameKey();
$valueKey = $this->csrf->getTokenValueKey();
$name = $request->getAttribute($nameKey);
$value = $request->getAttribute($valueKey);
$tokenArray = [
$nameKey => $name,
$valueKey => $value
];
return $response->write(json_encode($tokenArray));
}
and
public function postSignInService($request, $response, $args){
$auth = $this->auth->attempt(
$request->getParam('email'),
$request->getParam('password')
);
if(!$auth){
$data = array('status' => 'error');
$newResponse = $response->withJson($data, 203);
return $newResponse;
}
$data = array('status' => 'Successful login');
$newResponse = $response->withJson($data, 200);
return $newResponse;
}
and added routes for the methods.
How could i successfully authenticate with Ionic v3 and Angular v5?
