Android WebView js混合cookie和localStorage存储

一、cookie存储和取出：

（1）存储：

     -------------------
     **在loadURL之前调用**
     --------------------

    /**
     * 同步一下cookie
     */
    public void synCookies(String url) {
        CookieManager cookieManager = CookieManager.getInstance();
        cookieManager.setAcceptCookie(true);
        cookieManager.acceptCookie();
        cookieManager.removeSessionCookie();// 移除
        cookieManager.removeAllCookie();
        /**
         * cookies是在HttpClient中获得的cookie
         */
        String token = (String) SpUtils.getParam(getApplicationContext(), Constant.TOKEN, "'");
        String phone = (String) SpUtils.getParam(getApplicationContext(), Constant.PHONENUMBER, "'");
        if (TextUtils.isEmpty(token)) {
            return;
        }
        cookieManager.setCookie(url, Constant.UICPS_USERID + "=" + token);
        cookieManager.setCookie(url, Constant.UICPS_USERPHONE + "=" + phone);
        /**
         *  判断系统当前版本，同步方式不一样
         */
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
            cookieManager.flush();
        } else {
            CookieSyncManager.createInstance(getApplicationContext()).sync();
        }
    }

（2）取出：

       url:web地址
       if (CookieManager.getInstance().hasCookies()) {//如果存在token就获取
            String cookies = CookieManager.getInstance().getCookie(url);
       }

二、LocalStorage存储和取出：  设置LocalStorage 在onPageFinished中调用

(1)存储

第一步：设置

 //存储设置
 webSettings.setDomStorageEnabled(true);
 webSettings.setAppCacheMaxSize(1024 * 1024 * 8);
 String appCachePath = getContext().getCacheDir().getAbsolutePath();
 webSettings.setAppCachePath(appCachePath);

第二步：存储

    /**
     * 网页加载完毕
     */

    @Override
    protected void onPageFinished(WebView view, String url) {
        writeLocalStorage();
    }

    /**
     * 写入LocalStorage
     */
    private void writeLocalStorage() {
        String token = (String) SpUtils.getParam(getApplicationContext(), Constant.TOKEN, "");
        String phone = (String) SpUtils.getParam(getApplicationContext(), Constant.PHONENUMBER, "");
        if (TextUtils.isEmpty(token)) {
            return;
        }
        if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.KITKAT) {
            if (contentWebView != null) {
                contentWebView.evaluateJavascript("window.localStorage.setItem('" + Constant.UICPS_USERID + "','" + token + "');", null);
                contentWebView.evaluateJavascript("window.localStorage.setItem('" + Constant.UICPS_USERPHONE + "','" + phone + "');", null);
            }
        } else {
            if (contentWebView != null) {
                contentWebView.loadUrl("javascript:localStorage.setItem('" + Constant.UICPS_USERID + "','" + token + "');");
                contentWebView.loadUrl("javascript:localStorage.setItem('" + Constant.UICPS_USERPHONE + "','" + phone + "');");
            }
        }
    }

（2）取出

在前端取出

 //token为存入的key值
 localStorage.getItem("token")
