Android混合开发模式下Cookies的管理

Android混合开发不管是使用的哪种hybird框架都是基于WebView实现的，所以我们需要在原生页面拿到服务器返回的cookies的时候将其同步到WebView中，同时在原生页面调用服务器api之前，从WebView_cookies.db中拿到最新的cookies写入http请求头当中，只有这样才能保持用户的登录状态，否则服务器检测到cookies中的sessionId过期后会返回错误码提示用户登录失效。以okhttp网络框架为例，通过写两个拦截器分别在发送http请求的时候获取本地cookies写到http header当中，在接收http响应的时候从响应头中拿到最新的cookies并刷新本地cookies：

public class AddCookieInterceptor implements Interceptor {
    @Override
    public Response intercept(Chain chain) throws IOException {
        final Context context = PApplication.getInstance();
        String cookies = Commons.getSSOCookie(context);
        Request.Builder builder = chain.request().newBuilder();
        if (EmptyHelper.isNotEmptyOrNotNull(cookies)) {
            Request newRequest = builder.addHeader("Cookie", cookies).build();
            return chain.proceed(newRequest);
        }
    }
}

public class ReceivedCookieInterceptor implements Interceptor{

    @Override
    public Response intercept(Chain chain) throws IOException {
        Response originalResponse = chain.proceed(chain.request());
        List<String> cookies = originalResponse.headers("Set-Cookie");
        if (!cookies.isEmpty()) {
            CookieManager cookieManager = CookieManager.getInstance();
            cookieManager.setAcceptCookie(true);// 允许接受 Cookie
            String domain = HeadDomin();
            for(String cookie : cookies){
                cookieManager.setCookie(domain,cookie);
            }
            cookieManager.flush();
        }
        return originalResponse;
    }
}
