Android 4.4 KitKat不接收Cookie

Question

在我的應用程序中，我向服務器發送POST請求，並從服務器接收響應。 然后從響應中收集不同的Cookie，尤其是用戶信息。 因此，我發送登錄請求並在服務器響應后接收cookie，以保持登錄。 在Android 4.3及更低版本中，我收到的Cookie很好，並且用戶成功登錄。 但是在Android 4.4中，用戶成功登錄，但是沒有收到Cookie。

Android是否已對此進行了重大更改？ 如果有人有任何建議，這是我的以下代碼。

private URL urlObj;
private HttpURLConnection connection;
private DataOutputStream dataOs;


private ArrayList<String> schools;
private ArrayList<Post> schoolPosts;
private String schoolID;
private String name;

private String userLoginCookie, sessionSeedCookie, sessionUidCookie, sPrefCookie;

private Context context;
private CookieStore store;

public DataParser(Context _context) {
    context = _context;
}

//First call whenever connecting across the user's network
private void establishConnection() throws IOException {
    urlObj = new URL(url);
    connection = (HttpURLConnection) urlObj.openConnection();
    CookieManager cookieManager = new CookieManager();

    cookieManager.setCookiePolicy(CookiePolicy.ACCEPT_ALL);
    CookieHandler.setDefault(cookieManager);
    store = cookieManager.getCookieStore();

    getCookies();
    connection.setRequestMethod("POST");
    connection.setRequestProperty("Content-Type","application/x-www-form-urlencoded");
    connection.setRequestProperty("Cookie", sessionSeedCookie+";"+sessionUidCookie+";"+userLoginCookie+";"+sPrefCookie);
    connection.setDoOutput(true);
    connection.setUseCaches(false);

    dataOs = new DataOutputStream(connection.getOutputStream());
}

//Called after communication is complete
private void disconnectAll() throws IOException {
    connection.disconnect();
    dataOs.close();
}

private void getCookies() {
    SharedPreferences settings = context.getSharedPreferences(PREFS_NAME, 0);
    userLoginCookie = settings.getString(USER_LOGIN, BLANK);
    Log.d(LOG, "Cookie: "+userLoginCookie);
    sessionSeedCookie = settings.getString(SESS_SEED, BLANK);
    Log.d(LOG, "Cookie: "+sessionSeedCookie);
    sessionUidCookie = settings.getString(SESS_UID, BLANK);
    Log.d(LOG, "Cookie: "+sessionUidCookie);
    sPrefCookie = settings.getString(S_PREF, "sPref="+BLANK);
    Log.d(LOG, "Cookie: "+sPrefCookie);
}

private void updateCookies() {
    SharedPreferences settings = context.getSharedPreferences(PREFS_NAME, 0);
    SharedPreferences.Editor editor = settings.edit();

    List<HttpCookie> cookieList = store.getCookies();
    for(int i=0; i<cookieList.size(); i++) {
        if(cookieList.get(i).getName().equals(USER_LOGIN)) 
            editor.putString(USER_LOGIN, cookieList.get(i).toString());
        else if(cookieList.get(i).getName().equals(SESS_SEED)) 
            editor.putString(SESS_SEED, cookieList.get(i).toString()); 
        else if(cookieList.get(i).getName().equals(SESS_UID)) 
            editor.putString(SESS_UID, cookieList.get(i).toString());
        else
            Log.d(LOG, "Found Extra Cookie: "+cookieList.get(i).getName());
    }
    sPrefCookie = settings.getString(S_PREF, "sPref="+BLANK);

    editor.commit(); //Save changes to the SharedPreferences
}       

//Logins User into Walkntrade
public String login(String email, String password) throws IOException {
    establishConnection(); //Instantiate all streams and opens the connection

    String query= "intent=login&password="+password+"&email="+email+"&rememberMe=true";
    dataOs.writeBytes(query);
    Log.d(LOG, "" + connection.getResponseCode());
    updateCookies();

    String response = readInputAsString(connection.getInputStream());

    Log.d(LOG, "Connection Status: "+response);

    disconnectAll();
    return response;
}

//Logs user out of Walkntrade
public void logout() throws IOException { 
    establishConnection();

    String query = "intent=logout";
    dataOs.writeBytes(query);
    Log.d(LOG, "" + connection.getResponseCode());
    updateCookies();

    disconnectAll();
}

//Returns user login status
public static boolean isUserLoggedIn(Context _context) {
    SharedPreferences settings = _context.getSharedPreferences(PREFS_NAME, 0);
    boolean isUserLoggedIn = settings.getBoolean(DataParser.CURRENTLY_LOGGED_IN, false);

    return isUserLoggedIn;
}

public String getUserName() throws IOException{
    establishConnection();

    String query = "intent=getUserName";
    dataOs.writeBytes(query);
    Log.d(LOG, ""+connection.getResponseCode());
    updateCookies();

    String response = readInputAsString(connection.getInputStream());

    disconnectAll();
    return response;
}

public String getUserAvatar() throws IOException {
    establishConnection();

    String query = "intent=getAvatar";
    dataOs.writeBytes(query);

    updateCookies();

    String response = readInputAsString(connection.getInputStream());

我解決了這個問題。 我從HttpUrlConnection和其他java.net東西切換到AndroidHttpClient和其他Apache Http類。 現在可以從Android API 19中檢索Cookie。

[編輯]我使用了AndroidHttpClient（ http://developer.android.com/reference/android/net/http/AndroidHttpClient.html ），並且遵循了一些Apache Http教程。 因此，在我稍微更改了代碼之后，它看起來像這樣：

private AndroidHttpClient httpClient; //Android Client, Uses User-Agent, and executes request
private HttpContext httpContext; //Contains CookieStore that is sent along with request
private CookieStore cookieStore; //Holds cookies from server
private HttpPost httpPost; //Contains message to be sent to client
private final String USER_AGENT = System.getProperty("http.agent"); //Unique User-Agent of current device

//First call whenever connecting across the user's network
private void establishConnection() {
    cookieStore = new BasicCookieStore();
    httpContext = new BasicHttpContext();
    httpContext.setAttribute(ClientContext.COOKIE_STORE, cookieStore); //Attach CookieStore to the HttpContext

    getCookies(); //Retrieve currently stored cookies

    httpClient = AndroidHttpClient.newInstance(USER_AGENT);
    httpPost = new HttpPost(url);
    httpPost.setHeader("Content-Type", "application/x-www-form-urlencoded");
    httpPost.setHeader("Cookie", sessionSeedCookie + ";" + sessionUidCookie + ";" + userLoginCookie + ";" + sPrefCookie);
}

//Called after communication is complete
private void disconnectAll() {
    httpClient.close();
}

//Sends out POST request and returns an InputStream
private InputStream processRequest(String query) throws IOException{
    httpPost.setEntity(new StringEntity(query)); //wraps the query into a String entity
    HttpResponse response = httpClient.execute(httpPost, httpContext); //Executes the request along with the cookie store
    Log.i(TAG, "Server Response Code: " + response.getStatusLine().getStatusCode()); //Reads response code from server

    updateCookies();

    return response.getEntity().getContent();
}

//Logins User into Walkntrade
public String login(String email, String password) throws IOException {
    establishConnection(); //Instantiate all streams and opens the connection
    String query= "intent=login&password="+password+"&email="+email+"&rememberMe=true";

    InputStream inputStream = processRequest(query);
    String serverResponse = readInputAsString(inputStream); //Reads message response from server

    disconnectAll();
    return serverResponse;
}

在KitKat 4.4更新之前，此代碼對我來說效果很好-

HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();

//handle cookies
CookieManager cookieManager = new CookieManager();
CookieHandler.setDefault(cookieManager);

它在4.4.2之后崩潰了（至少在我注意到的時候），並且不再收到Cookie。 只需在打開urlConnection之前移動CookieManager和CookieHandler即可，再次對其進行了修復。 例如。

//handle cookies
CookieManager cookieManager = new CookieManager();
CookieHandler.setDefault(cookieManager);

HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();
