|
|
|
* <p>Google任务API客户端类。</p>
|
|
|
* <p>设计意图：提供与Google任务API交互的核心功能，实现任务的创建、更新、删除等操作。</p>
|
|
|
* <p>核心职责：</p>
|
|
|
* <ul>
|
|
|
* <li>处理Google账号的登录认证</li>
|
|
|
* <li>执行Google任务的CRUD操作</li>
|
|
|
* <li>管理API请求的Cookie和会话状态</li>
|
|
|
* <li>处理网络请求和响应，包括压缩数据的解压</li>
|
|
|
* <li>将本地任务模型转换为Google任务API的JSON格式</li>
|
|
|
* </ul>
|
|
|
* <p>关键关联：</p>
|
|
|
* <ul>
|
|
|
* <li>与{@link GTaskManager}配合，提供任务同步的底层支持</li>
|
|
|
* <li>使用{@link Task}和{@link TaskList}类封装Google任务数据</li>
|
|
|
* <li>通过{@link NetworkFailureException}和{@link ActionFailureException}处理异常</li>
|
|
|
* <li>依赖{@link GTaskStringUtils}提供API交互所需的常量</li>
|
|
|
* </ul>
|
|
|
* <p>设计特点：</p>
|
|
|
* <ul>
|
|
|
* <li>采用单例模式，确保全局只有一个Google任务API客户端实例</li>
|
|
|
* <li>实现会话管理，避免频繁登录认证</li>
|
|
|
* <li>支持批量更新操作，提高API调用效率</li>
|
|
|
* <li>处理不同类型的网络压缩格式（gzip、deflate）</li>
