使用HTTPUrlConnection时如何保留cookie？

我已经开始使用推荐的广告，HTTPUrlConnection并从移走了DefaultHTTPClient。我无法重新粘合在一起的一件事是使用持久性Cookie存储。我想简单地将自定义cookie处理程序/管理器附加到我的连接中以存储cookie。Android文档并不是很有帮助，因为它将Cookie主题分为两行。

我以前使用过LoopJ PersistentCookieStore，效果很好。

关于如何在Android中设置可以附加到我的HTTPUrlConnection自动保存和检索cookie 的持久性cookie存储的想法？

谢谢

回答：

我花了几个小时，但我自己设法建立了一个自定义cookie存储。

您必须通过执行以下操作来附加它：

public class application extends Application {
    @Override
    public void onCreate() {
        super.onCreate();
       CookieManager cmrCookieMan = new CookieManager(new MyCookieStore(this.objContext), CookiePolicy.ACCEPT_ALL);
       CookieHandler.setDefault(cmrCookieMan);
       }
    }

这是实际的存储空间：

/*
 * This is a custom cookie storage for the application. This
 * will store all the cookies to the shared preferences so that it persists
 * across application restarts.
 */
class MyCookieStore implements CookieStore {
    /*
     * The memory storage of the cookies
     */
    private Map<URI, List<HttpCookie>> mapCookies = new HashMap<URI, List<HttpCookie>>();
    /*
     * The instance of the shared preferences
     */
    private final SharedPreferences spePreferences;
    /*
     * @see java.net.CookieStore#add(java.net.URI, java.net.HttpCookie)
     */
    public void add(URI uri, HttpCookie cookie) {
        System.out.println("add");
        System.out.println(cookie.toString());
        List<HttpCookie> cookies = mapCookies.get(uri);
        if (cookies == null) {
            cookies = new ArrayList<HttpCookie>();
            mapCookies.put(uri, cookies);
        }
        cookies.add(cookie);
        Editor ediWriter = spePreferences.edit();
        HashSet<String> setCookies = new HashSet<String>();
        setCookies.add(cookie.toString());
        ediWriter.putStringSet(uri.toString(), spePreferences.getStringSet(uri.toString(), setCookies));
        ediWriter.commit();
    }
   /*
    * Constructor
    * 
    * @param  ctxContext the context of the Activity
    */

    public MyCookieStore(Context ctxContext) {
        spePreferences = ctxContext.getSharedPreferences("CookiePrefsFile", 0);
        Map<String, ?> prefsMap = spePreferences.getAll();
        for(Map.Entry<String, ?> entry : prefsMap.entrySet()) {
            for (String strCookie : (HashSet<String>) entry.getValue()) {
                if (!mapCookies.containsKey(entry.getKey())) {
                    List<HttpCookie> lstCookies = new ArrayList<HttpCookie>();
                    lstCookies.addAll(HttpCookie.parse(strCookie));
                    try {
                        mapCookies.put(new URI(entry.getKey()), lstCookies);
                    } catch (URISyntaxException e) {
                        e.printStackTrace();
                    }
                } else {
                    List<HttpCookie> lstCookies = mapCookies.get(entry.getKey());
                    lstCookies.addAll(HttpCookie.parse(strCookie));
                    try {

                }
                System.out.println(entry.getKey() + ": " + strCookie);
            }
        }
    }
    /*

        return mapCookies.get(uri);
    }
    /*

    public boolean removeAll() {
        mapCookies.clear();
        return true;
    }
