android本地儲存Cookie和還原到cookiestore

標籤：android   http   java   get   os   類   

儲存cookie，讀取cookie以及判斷cookie是否存在

```java

public class Local {

private static SharedPreferences shared;

public static void setShared(SharedPreferences shared) {Local.shared = shared;}

public static void saveStrCookie(String cookie) {SharedPreferences.Editor editor = shared.edit();editor.putString(Constant.COOKIE_NAME, cookie);editor.commit();}

public static boolean hasCookie() {String sessionid = shared.getString(Constant.COOKIE_NAME, null);

if (sessionid == null || sessionid.equals("")) {LogUtil.i("hasCookie return false");return false;}LogUtil.i("hasCookie return true");return true;}

public static String getCookie() {String sessionid = shared.getString(Constant.COOKIENAME, null);LogUtil.e("====>getCookie =" + _sessionid);return sessionid;}

public static void saveCookie(DefaultHttpClient httpClient) {List cookies = httpClient.getCookieStore().getCookies();String strCookie = "";for (Cookie cookie : cookies) {strCookie = cookie.getValue().toString();}LogUtil.e("====>saveCookie = " + strCookie);saveStrCookie(strCookie);}}```

將cookie加入CookieStore。主要就是BasicClientCookie這個類

```java

private void setRequestCookies(DefaultHttpClient client) {

String cookie = Local.getCookie();

Log.i("COOKIE VALUE", cookie);

if (!TextUtils.isEmpty(cookie)) {

BasicClientCookie c = new BasicClientCookie(Constant.COOKIE_NAME,

cookie);

c.setVersion(0);

c.setPath("/");

c.setDomain(Constant.COOKIE_DOMAIN);

client.getCookieStore().addCookie(c);

}

}```
