OkHttp保存和使用cookie

1. client.cookieJar()用来设置cookie

 OkHttpClient okHttpClient = new OkHttpClient.Builder()                //打印日志                .addInterceptor(interceptor)                //设置Cache目录                .cache(cache(context))                //失败重连                .retryOnConnectionFailure(true)                //time out                .readTimeout(60000, TimeUnit.SECONDS)                .connectTimeout(60000, TimeUnit.SECONDS)                //缓存cookie                .cookieJar(new CookieManager(context))                .build();

其中cookieManager的代码为：

public class CookieManager implements CookieJar{    Context context;     private  PersistentCookieStore cookieStore ;     public CookieManager(Context context) {        // TODO Auto-generated constructor stub         this.context=context;         cookieStore= new PersistentCookieStore(context);    }    @Override    public List<Cookie> loadForRequest(HttpUrl url) {        List<Cookie> cookies = cookieStore.get(url);        return cookies;    }    @Override    public void saveFromResponse(HttpUrl url, List<Cookie> cookies) {        // TODO Auto-generated method stub        if (cookies != null && cookies.size() > 0) {            for (Cookie item : cookies) {                cookieStore.add(url, item);            }        }    }}

2. CookieMaager中需要两个辅助类，用来保存cookie

第一个辅助类
