    `LoggingEventListener.androidLogging()` write HTTP calls or events to Logcat.

 *  New: `OkHttpClient.webSocketCloseTimeout` configures how long a web socket connection will wait
    for a graceful shutdown before it performs an abrupt shutdown.

 *  Fix: Honor `RequestBody.isOneShot()` in `MultipartBody`

 *  Fix in `okhttp-coroutines`: Don't leak response bodies in `executeAsync()`. We had a bug where

* **WebSocket** support.
* In-process background tasks.
* Startup and shutdown events.
* Test client built on HTTPX.
* **CORS**, GZip, Static Files, Streaming responses.
* **Session and Cookie** support.
* 100% test coverage.
* 100% type annotated codebase.

通过 **FastAPI** 你可以获得所有 **Starlette** 的特性（FastAPI 就像加强版的 Starlette）：

* 令人惊叹的性能。它是[Python 可用的最快的框架之一，和 **NodeJS** 及 **Go** 相当](https://github.com/encode/starlette#performance)。
* **支持 WebSocket**。
* 进程内后台任务。
* Startup 和 shutdown 事件。
* 测试客户端基于 HTTPX。
* **CORS**、GZip、静态文件、流响应。
* 支持 **Session 和 Cookie**。
* 100% 测试覆盖率。
* 代码库 100% 类型注释。
