Android 4.4 KitKat未接收cookie

在我的应用程序中，我向服务器发送POST请求，并从服务器接收响应。 从回复中我收集了不同的cookies，特别是用户信息。因此，我发送一个登录请求，并在服务器响应后接收cookies，以保持登录。在安卓4.3及以下版本中，我收到的cookies很好，用户登录成功。但在安卓4.4中，用户成功登录，但没有收到cookie

安卓系统是否改变了一些重要的事情，让这一切发生了？如果有人有任何建议，下面是我的代码

对于（int i=0；i我修复了这个问题。我从HttpUrlConnection和其他java.net内容切换到AndroidHttpClient和其他Apache Http类。现在可以从Android API 19检索cookie

[编辑]
我使用了AndroidHttpClient（），并遵循了一些Apache Http教程。因此，在对代码稍作修改后，看起来如下所示：

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，这段代码对我来说运行良好-

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

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

它在4.4.2之后坏了（至少我当时注意到了），并且不再收到cookies。只需在打开urlConnection之前移动CookieManager和CookieMhandler，就可以再次修复它。奇怪的是，它以前工作过

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

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

你能详细说明一下吗？自从4.4坏了我的电脑后，我就遇到了这个问题Cookies@WallyHale我添加了用于新实现的实际代码。我还注意到使用Apache客户端的速度有所提高。
