Google Chrome未设置从NodeJS / Express服务器发送的Cookie

Question

I am trying to set up authenticated endpoints in my backend(Express/Node/Mongo with express-session) and can send a cookie to the client (Chrome Version 53.0.2785.143) in the Response Header but when I look for the cookie in the Dev Console under Application->Storage->Cookies-> http://localhost:8100 it is not there, and so nothing is sent back to the server in subsequent Request Headers. However, when I test the code as written using Postman it appears that everything works meaning that the server sends a cookie on login and the cookie is returned when I GET authenticated endpoints.

Response Headers
HTTP/1.1 200 OK
X-Powered-By: Express
Vary: X-HTTP-Method-Override
Access-Control-Allow-Origin: *
Access-Control-Allow-Methods: DELETE, PUT, GET

Settings object for the session ID cookie:

session ID cookie name = 'connect.sid'.

Ionic2 service to login user.
public loginUser(user:Object):Observable<any>{
    let headers = new Headers();
    headers.append('Content-Type', 'application/json');
    return this.http.post('http://localhost:8000/login', JSON.stringify(user), {headers: headers})
            .map(this.extractData)
            .catch(this.handleError)
}

public extractData(res: Response) {
    console.log(res.headers); //cookie does not log here in response
    let body = res.json();
    return body || { };
}

Usually, chrome won't save cookies for localhost. Please disable your web security in chrome.
