HTTPclient和cookie的问题

Question

I am currently working on a mobile app that is going to communicate with a RESTfull server over the HTTP-protocol. For this I have made a working code and got the communication working.

For the server to identify users I wanted to use cookies (some kind of sessions cookie). So I have started out with the two following helper-methods to create a HttpClient and a context (that includes my cookie).

// Gets a standard client - set to HTTP1.1
private HttpClient getClient() {
    HttpParams params = new BasicHttpParams();
    params.setParameter(CoreProtocolPNames.PROTOCOL_VERSION, HttpVersion.HTTP_1_1);
    return new DefaultHttpClient(params);
}

// Gets the context with cookies to be used. This is to make each user unique
private HttpContext getHttpContext(String server) {
    CookieStore cookieStore = new BasicCookieStore();
    BasicClientCookie cookie = new BasicClientCookie("X-ANDROID-USER", "some name");
    cookie.setDomain(server);
    cookie.setPath("/");
    cookie.setVersion(1);

    cookieStore.addCookie(cookie);
    HttpContext localContext = new BasicHttpContext();
    localContext.setAttribute(ClientContext.COOKIE_STORE, cookieStore);
    return localContext;
}

I then connect to the server using the following (read function). That basically takes the Client and Conext generate by the last two helper methods and do a normal GET-request.
// Connects to the restfull server and returns the return value (get request)

 private String restfullRead(URI uri, String server) { // Sets up the different objects needed to read a HttpRequest HttpClient client = this.getClient(); HttpGet request = new HttpGet(); request.setURI(uri); HttpContext context = this.getHttpContext(server); // Connects to the server and reads response try { HttpResponse response = client.execute(request, context); reader.close(); } catch (Exception e) { return ""; } 

When I run this to my server I get the following request.
GET /info/1 HTTP/1.1
Host: 192.168.0.191:8080
Connection: Keep-Alive

As you can see, this does not include any cookies. Thats why I wonder, why arent the cookie made in "getHttpContext" sent in the request?

How do I make an http request using cookies on Android?

// EDIT

1.) Your Android app sends it's unique NFC-Tag to the server.

2.) The server create a new unique token and builds a releation beween the token and the NFC-Tag

3.) Whenever your app is sending a request, send the unique NFC-Tag too.

4.) The server will check the NFC-Tag and searchs the token and now your device is identified

Sending custom header:

HttpGet get = new HttpGet(getURL);
get.addHeader("NFC", "YOUR NFC-TAG");
get.addHeader("Some more header", "more infos");
