Maintain session between HttpUrlConnection Calls (Native/Webview)

session

Let me start with what I desire:

I want to make an app which is part native and part webviews.

Problem - Maintain a session between native and webview parts.

My Approach to handle this:

I intend to implement a native login, in which I present the user with two EditTextboxes and a button, the user enters credentials and I post them as JSON to the server.

The Server responds with success or false. Based on Success flag I read the header values for this connection and extract the SessionCookie:

switch (responseCode) {
                case 200:

                    BufferedReader in = new BufferedReader(new InputStreamReader(conn.getInputStream()));
                    String inputLine;
                    response = new StringBuffer();
                    while ((inputLine = in.readLine()) != null) {
                        response.append(inputLine);
                    }
                    in.close();

                   //IF SUCCESS

                    Map<String, List<String>> map = conn.getHeaderFields();

                    for (Map.Entry<String, List<String>> entry : map.entrySet()) {
                        System.out.println("Key : " + entry.getKey() + " ,Value : " + entry.getValue());
                    }

                    SSID = map.get("Set-Cookie").toString();
                    SSID = SSID.substring(1,SSID.length()-1);
                    return response.toString();
            }

and which looks like below: 

Set-Cookie ,Value : [PHPSESSID=e407ef64abb71b1ea2b8e4b30db76cf0; path=/, ci_session=a%3A0%3A%7B%7D; expires=Thu, 06-Nov-2014 16:54:57 GMT; Max-Age=-31500000; path=/, ci_session=a%3A5%3A%7Bs%3A10%3A%22session_id%22%3Bs%3A32%3A%22caedca696344458e7aa1b4ad02b3cfa0%22%3Bs%3A10%3A%22ip_address%22%3Bs%3A13%3A%22182.59.130.42%22%3Bs%3A10%3A%22user_agent%22%3Bs%3A60%3A%22Dalvik%2F2.1.0+%28Linux%3B+U%3B+Android+5.1.1%3B+Nexus+5+Build%2FLMY48B%29%22%3Bs%3A13%3A%22last_activity%22%3Bi%3A1446792897%3Bs%3A9%3A%22user_data%22%3Bs%3A0%3A%22%22%3B%7D5f4013e4a2edd2eb891ec8a2b8e8716e; expires=Sun, 05-Nov-2017 06:54:57 GMT; Max-Age=63072000; path=/, ci_session=a%3A4%3A%7Bs%3A10%3A%22session_id%22%3Bs%3A32%3A%22caedca696344458e7aa1b4ad02b3cfa0%22%3Bs%3A10%3A%22ip_address%22%3Bs%3A13%3A%22182.59.130.42%22%3Bs%3A10%3A%22user_agent%22%3Bs%3A60%3A%22Dalvik%2F2.1.0+%28Linux%3B+U%3B+Android+5.1.1%3B+Nexus+5+Build%2FLMY48B%29%22%3Bs%3A13%3A%22last_activity%22%3Bi%3A1446792897%3B%7Dc7eaa0945a7056db3cb9d336a02e5ecb; expires=Sun, 05-Nov-2017 06:54:57 GMT; Max-Age=63072000; path=/, ci_session=a%3A4%3A%7Bs%3A10%3A%22session_id%22%3Bs%3A32%3A%22caedca696344458e7aa1b4ad02b3cfa0%22%3Bs%3A10%3A%22ip_address%22%3Bs%3A13%3A%22182.59.130.42%22%3Bs%3A10%3A%22user_agent%22%3Bs%3A60%3A%22Dalvik%2F2.1.0+%28Linux%3B+U%3B+Android+5.1.1%3B+Nexus+5+Build%2FLMY48B%29%22%3Bs%3A13%3A%22last_activity%22%3Bi%3A1446792897%3B%7Dc7eaa0945a7056db3cb9d336a02e5ecb; expires=Sun, 05-Nov-2017 06:54:57 GMT; Max-Age=63072000; path=/]

Caveat: In the above expires=Thu, 06-Nov-2014 16:54:57 GMT

Now I want to go to a webview and add this cookie to the header, which I am doing like: 

Map<String, String> abc = new HashMap<String, String>();
            abc.put("Cookie", UniversalHttpUrlConnection.SSID);
            webView.loadUrl("https://someUrl/show_all", abc);

The above however does not work.

I tried a different approach, just to read the HTML from the above webview URL: 

 public static String doHttpUrlConnectionAction(String desiredUrl, String headerValue)
            throws Exception {
        URL url = null;
        BufferedReader reader = null;
        StringBuilder stringBuilder;

        try {

            url = new URL(desiredUrl);
            HttpURLConnection connection = (HttpURLConnection) url.openConnection();
            connection.setRequestProperty("Cookie", headerValue);

            connection.setRequestMethod("GET");

            connection.setDoOutput(true);


            connection.setReadTimeout(15 * 1000);
            connection.connect();


            reader = new BufferedReader(new InputStreamReader(connection.getInputStream()));
            stringBuilder = new StringBuilder();

            String line = null;
            while ((line = reader.readLine()) != null) {
                stringBuilder.append(line + "\n");
            }
            return stringBuilder.toString();
        } catch (Exception e) {
            e.printStackTrace();
            throw e;
        } finally {

            if (reader != null) {
                try {
                    reader.close();
                } catch (IOException ioe) {
                    ioe.printStackTrace();
                }
            }
        }

    }

The HTML I get is that of the Login page, which is essentially a redirect - as the server does not recognize the session and redirects me. What am I missing here? How can I continue the session?

Edit - further debugging:

Using a deprecated:

HttpClient httpClient = new DefaultHttpClient(); //

I get these headers:

Observation: Set-Cookie is packed together, four instances.

When I try this in the Advanced Rest Client manually, everything works proper. I get the desired HTML page - authenticated.

Observation: The Advanced Rest Client App gives proper results only if I am logged into the website, in the same browser. So essentially the cookies are getting overridden.

Observation

I got fed up trying to get the session cookies from the HttpUrlConnection, what I did for a change is to load a webview and login inside of it.

Second I put up a button which fires my HttpUrlConnection - and tries to access a page which requires authentication.

Inside of this HttpUrlConnection I did something like this: 

 CookieManager cookieManager = CookieManager.getInstance();
            String cookie = cookieManager.getCookie(new URL("https://urlinQuestion.com").getHost());
            System.out.println("Cookie from cookie store" + cookie);
            connection.setRequestProperty("Cookie", cookie);

So I pass the cookies which I get in the webView to the HttpUrlCOnnection. It works. Now what I feel is that inorder to reverse the order of events (As I want the cookies form UrlConnection - pass them to webview) I will have to update the cookie manager. (New Voyage starts here)

For record sake I am adding two cookies below: The first one does not work, the second one I get from the webview way and works, I find no difference in semantics though:

The closest I could get to this is, by using a webview as login. Then you can continue your session in the HttpUrlConnection, with the cookies fetched from webview. The cookies can be used as follows: 

HttpURLConnection urlConnection = null;
try {
    urlConnection = (HttpURLConnection) url.openConnection();

    // Fetch and set cookies in requests
    CookieManager cookieManager = CookieManager.getInstance();
    String cookie = cookieManager.getCookie(urlConnection.getURL().toString());
    if (cookie != null) {
        urlConnection.setRequestProperty("Cookie", cookie);
    }
    urlConnection.connect();

    // Get cookies from responses and save into the cookie manager
    List cookieList = urlConnection.getHeaderFields().get("Set-Cookie");
    if (cookieList != null) {
        for (String cookieTemp : cookieList) {
            cookieManager.setCookie(urlConnection.getURL().toString(), cookieTemp);
        }
    }

    InputStream in = new BufferedInputStream (urlConnection.getInputStream());
} catch (IOException e) {
    e.printStackTrace();
} finally {
    if (urlConnection != null) {
        urlConnection.disconnect();
    }
}

It is Cookie header you are suppose to send on the request, not Set-Cookie.
Please read https://www.rfc-editor.org/rfc/rfc6265 for examples.

When your client receives session cookie in HTTP response header as

Set-Cookie: PHPSESSID=e407ef64abb71b1ea2b8e4b30db76cf0; path=/

It should add this cookie to subsequent HTTP requests header as

Cookie: PHPSESSID=e407ef64abb71b1ea2b8e4b30db76cf0

EDIT:

The native PHPSESSID is a bit confusing, but it should be ok to use the last value of ci_session cookie, e.g. from the response

Set-Cookie ,Value : [PHPSESSID=e407ef64abb71b1ea2b8e4b30db76cf0; path=/, ci_session=a%3A0%3A%7B%7D; expires=Thu, 06-Nov-2014 16:54:57 GMT; Max-Age=-31500000; path=/, ci_session=a%3A5%3A%7Bs%3A10%3A%22session_id%22%3Bs%3A32%3A%22caedca696344458e7aa1b4ad02b3cfa0%22%3Bs%3A10%3A%22ip_address%22%3Bs%3A13%3A%22182.59.130.42%22%3Bs%3A10%3A%22user_agent%22%3Bs%3A60%3A%22Dalvik%2F2.1.0+%28Linux%3B+U%3B+Android+5.1.1%3B+Nexus+5+Build%2FLMY48B%29%22%3Bs%3A13%3A%22last_activity%22%3Bi%3A1446792897%3Bs%3A9%3A%22user_data%22%3Bs%3A0%3A%22%22%3B%7D5f4013e4a2edd2eb891ec8a2b8e8716e; expires=Sun, 05-Nov-2017 06:54:57 GMT; Max-Age=63072000; path=/, ci_session=a%3A4%3A%7Bs%3A10%3A%22session_id%22%3Bs%3A32%3A%22caedca696344458e7aa1b4ad02b3cfa0%22%3Bs%3A10%3A%22ip_address%22%3Bs%3A13%3A%22182.59.130.42%22%3Bs%3A10%3A%22user_agent%22%3Bs%3A60%3A%22Dalvik%2F2.1.0+%28Linux%3B+U%3B+Android+5.1.1%3B+Nexus+5+Build%2FLMY48B%29%22%3Bs%3A13%3A%22last_activity%22%3Bi%3A1446792897%3B%7Dc7eaa0945a7056db3cb9d336a02e5ecb; expires=Sun, 05-Nov-2017 06:54:57 GMT; Max-Age=63072000; path=/, ci_session=a%3A4%3A%7Bs%3A10%3A%22session_id%22%3Bs%3A32%3A%22caedca696344458e7aa1b4ad02b3cfa0%22%3Bs%3A10%3A%22ip_address%22%3Bs%3A13%3A%22182.59.130.42%22%3Bs%3A10%3A%22user_agent%22%3Bs%3A60%3A%22Dalvik%2F2.1.0+%28Linux%3B+U%3B+Android+5.1.1%3B+Nexus+5+Build%2FLMY48B%29%22%3Bs%3A13%3A%22last_activity%22%3Bi%3A1446792897%3B%7Dc7eaa0945a7056db3cb9d336a02e5ecb; expires=Sun, 05-Nov-2017 06:54:57 GMT; Max-Age=63072000; path=/]

add to the folowing header to the webview request:

abc.put("Cookie", "ci_session=a%3A4%3A%7Bs%3A10%3A%22session_id%22%3Bs%3A32%3A%2221d4f88af57e9c7477f48e0695bdb979%22%3Bs%3A10%3A%22ip_address%22%3Bs%3A13%3A%22182.59.216.32%22%3Bs%3A10%3A%22user_agent%22%3Bs%3A40%3A%22Apache-HttpClient%2FUNAVAILABLE+%28java+1.4%29%22%3Bs%3A13%3A%22last_activity%22%3Bi%3A1446884548%3B%7D30e2cc6561b3fb9659c7809d0c82946d");

I would recommend to iterate over SSID = map.get("Set-Cookie"), test each individual 'Set-Cookie' header with something like /(ci_session=.*?);/ regex, and return the last match.

Please note, that User-Agent header from your webview should match user_agent in the session. In the cookie above it is Apache-HttpClient/UNAVAILABLE (java 1.4), and it seems that webview uses Dalvik/2.1.0 (Linux; U; Android 5.1.1; Nexus 5 Build/LMY48B).

A brilliant implementation of the java.net.CookieManager.

I've implemented my own idea. It's actually pretty cool. I've created my own implementation of java.net.CookieManager which forwards all requests to the WebViews' webkit android.webkit.CookieManager. This means no sync is required and HttpURLConnection uses the same cookie storage as the WebViews.



Class WebkitCookieManagerProxy:

import java.io.IOException;
import java.net.CookieManager;
import java.net.CookiePolicy;
import java.net.CookieStore;
import java.net.URI;
import java.util.Arrays;
import java.util.List;
import java.util.Map;

public class WebkitCookieManagerProxy extends CookieManager 
{
    private android.webkit.CookieManager webkitCookieManager;

    public WebkitCookieManagerProxy()
    {
        this(null, null);
    }

    public WebkitCookieManagerProxy(CookieStore store, CookiePolicy cookiePolicy)
    {
        super(null, cookiePolicy);

        this.webkitCookieManager = android.webkit.CookieManager.getInstance();
    }

    @Override
    public void put(URI uri, Map<String, List<String>> responseHeaders) throws IOException 
    {
        // make sure our args are valid
        if ((uri == null) || (responseHeaders == null)) return;

        // save our url once
        String url = uri.toString();

        // go over the headers
        for (String headerKey : responseHeaders.keySet()) 
        {
            // ignore headers which aren't cookie related
            if ((headerKey == null) || !(headerKey.equalsIgnoreCase("Set-Cookie2") || headerKey.equalsIgnoreCase("Set-Cookie"))) continue;

            // process each of the headers
            for (String headerValue : responseHeaders.get(headerKey))
            {
                this.webkitCookieManager.setCookie(url, headerValue);
            }
        }
    }

    @Override
    public Map<String, List<String>> get(URI uri, Map<String, List<String>> requestHeaders) throws IOException 
    {
        // make sure our args are valid
        if ((uri == null) || (requestHeaders == null)) throw new IllegalArgumentException("Argument is null");

        // save our url once
        String url = uri.toString();

        // prepare our response
        Map<String, List<String>> res = new java.util.HashMap<String, List<String>>();

        // get the cookie
        String cookie = this.webkitCookieManager.getCookie(url);

        // return it
        if (cookie != null) res.put("Cookie", Arrays.asList(cookie));
        return res;
    }

    @Override
    public CookieStore getCookieStore() 
    {
        // we don't want anyone to work with this cookie store directly
        throw new UnsupportedOperationException();
    }
}

And use it by doing this on your application initialization:

android.webkit.CookieSyncManager.createInstance(appContext);
// unrelated, just make sure cookies are generally allowed
android.webkit.CookieManager.getInstance().setAcceptCookie(true);

// magic starts here
WebkitCookieManagerProxy coreCookieManager = new WebkitCookieManagerProxy(null, java.net.CookiePolicy.ACCEPT_ALL);
java.net.CookieHandler.setDefault(coreCookieManager);
