cookie相关类：

cookie相关类：

        android.webkit.CookieSyncManager//deprecated，CookieSyncManager extends WebSyncManager
        android.webkit.CookieManager//abstract

        java.net.CookieManager//CookieManager extends CookieHandler
        java.net.CookieHandler//abstract
        java.net.CookieStore//interface
        java.net.CookiePolicy//interface

这里写图片描述

1、webkit.CookieSyncManager


webkit.CookieSyncManager：

        //android.webkit
        //过时，手动同步cookie
        CookieSyncManager cookieSyncManagerWeb = CookieSyncManager.createInstance(this);

        cookieSyncManagerWeb.sync();//同步cooike
        cookieSyncManagerWeb.resetSync();
        cookieSyncManagerWeb.startSync();
        cookieSyncManagerWeb.stopSync();

        CookieSyncManager syncManager = CookieSyncManager.getInstance();


//activity中的oncreate（）方法中注册cookiemanager

        CookieSyncManager.createInstance(this);

2、webkit.CookieManager：


webkit.CookieManager：

        //android.webkit
        //推荐使用，自动同步cooike
        android.webkit.CookieManager cookieManagerWeb = android.webkit.CookieManager.getInstance();

        cookieManagerWeb.removeAllCookie();//清除cooike
        cookieManagerWeb.acceptCookie();
        cookieManagerWeb.removeSessionCookie();
        cookieManagerWeb.flush();
        cookieManagerWeb.removeExpiredCookie();
        cookieManagerWeb.setAcceptCookie(true);
        boolean hasCookies = cookieManagerWeb.hasCookies();
        String cookie = cookieManagerWeb.getCookie(url);
        cookieManagerWeb.setCookie(url, cookie);

网络请求类中设置和获取cookie的方法

    //android.webkit
    private String getCookie() {
        android.webkit.CookieManager cookieManager = android.webkit.CookieManager.getInstance();
        String cookie = cookieManager.getCookie("cookie");
        if (cookie != null) {
            return cookie;
        } else {
            return "";
        }
    }

    //android.webkit
    private void setCookie(String cookie) {
        android.webkit.CookieManager cookieManager = android.webkit.CookieManager.getInstance();
        cookieManager.setCookie("cookie", cookie);
    }

    /**
     * 存储cookie
     */
    protected void setCookies(Map<String, List<String>> headerFields) {
        if (null == headerFields) {
            return;
        }

        List<String> cookies = headerFields.get("Cookie");
        if (null == cookies) {
            return;
        }

        for (String cookie : cookies) {
            setCookie(cookie);
        }
    }   


//
    connection = (HttpURLConnection) requestUrl.openConnection();
    connection.setRequestProperty("Cookie", getCookie());//获取cooike
    setCookies(connection.getHeaderFields());//设置cooike

3、net.CookieManager：


net.CookieManager：

        //java.net
        java.net.CookieManager cookieManagerNet = new java.net.CookieManager();
        java.net.CookieHandler.setDefault(cookieManagerNet);

        CookieHandler cookieHandler = CookieHandler.getDefault();

        CookieStore cookieStore = cookieManagerNet.getCookieStore();

        cookieManagerNet.setCookiePolicy(new CookiePolicy() {
            @Override
            public boolean shouldAccept(URI uri, HttpCookie cookie) {
                return false;
            }
        });

        try {
            URI uri = new URI(url);
            Map<String, List<String>> stringListMap = new HashMap<>();
            cookieManagerNet.put(uri, stringListMap);

            cookieManagerNet.get(uri, stringListMap);
        } catch (URISyntaxException | IOException e) {
            e.printStackTrace();
        }

参考：Android WebView清除cookie?

WebView清除cooike及缓存

//WebView清除cooike及缓存
        WebView webView = new WebView(this);

        webView.getSettings().setCacheMode(WebSettings.LOAD_NO_CACHE);
        webView.clearHistory();
        webView.clearFormData();
        webView.clearCache(true);

        CookieSyncManager.createInstance(webView.getContext());
        //CookieSyncManager清除还需要手动同步
        CookieSyncManager.getInstance().sync();

        CookieManager cookieManager = CookieManager.getInstance();
        cookieManager.setAcceptCookie(true);
        cookieManager.removeSessionCookie();
        cookieManager.removeAllCookie();



public static void synCookies(Context context, String url) {
        CookieSyncManager.createInstance(context);
        CookieManager cookieManager = CookieManager.getInstance();
        cookieManager.setCookie(url, "uid=1243432");
        CookieSyncManager.getInstance().sync();
}

private void removeCookie(Context context) {
        CookieSyncManager.createInstance(context);
        CookieManager cookieManager = CookieManager.getInstance();
        cookieManager.removeAllCookie();
        CookieSyncManager.getInstance().sync();
}
