How to access Response cookies in angular2?

I'm trying to access this cookies (the response ones):

When I open the request in the chrome debug tools in the network section I can clearly see that the cookies are present, but how can I access those values from my code? I've never worked with cookies before and I don't know what to do to "extract" them... I'm working on a Ionic2 project using Http.

I've read that the allowCredentials: true header has to be sent but that didn't work...

Here's the request/response details:




Here's the service:


public callLogin(service_guid: string, pos_guid: string, login_data: Object) {

return this.http.post(
this.url + service_guid + "/" + pos_guid + "/ack",
login_data,
{withCredentials: true}
)
.map(response => response.headers);
}

And the caller:


this.__posService.callLogin(login_data.service_guid, login_data.pos_guid, {"password": data.password})
.subscribe(
res => {
console.log("Success:");
console.log(res.get("apsession"); // this returns undefined
},
err => {
console.log("Error:");
}
);


When I try to access the cookie from the header it returns undefined. What am I doing wrong here?
