### Asynchronous Get ([.kt][AsynchronousGetKotlin], [.java][AsynchronousGetJava])

Download a file on a worker thread, and get called back when the response is readable. The callback is made after the response headers are ready. Reading the response body may still block. OkHttp doesn't currently offer asynchronous APIs to receive a response body in parts.

这在大多数情况下都能正常运行。😎

例如，您可以使用该命令在容器、服务器等环境中启动您的 **FastAPI** 应用。

## ASGI 服务器 { #asgi-servers }

让我们深入了解一些细节。

FastAPI 使用了一种用于构建 Python Web 框架和服务器的标准，称为 <abbr title="Asynchronous Server Gateway Interface - 异步服务器网关接口">ASGI</abbr>。FastAPI 本质上是一个 ASGI Web 框架。

要在远程服务器上运行 **FastAPI** 应用（或任何其他 ASGI 应用），您需要一个 ASGI 服务器程序，例如 **Uvicorn**。它是 `fastapi` 命令默认使用的 ASGI 服务器。

除此之外，还有其他一些可选的 ASGI 服务器，例如：

 * try (Response response = call.execute()) {
 * ... // Use the response.
 * }
 * ```
 *
 * You can use a similar block for asynchronous calls:
 *
 * ```java
 * Call call = client.newCall(request);
 * call.enqueue(new Callback() {
 *   public void onResponse(Call call, Response response) throws IOException {
 *     try (ResponseBody responseBody = response.body()) {
 *     ... // Use the response.

  }

   * allows the user to close all the closeable objects that were captured during it for later
   * closing.
   *
   * <p>The asynchronous operation will have completed before this object is created.
   *
   * @param <V> the type of the value of a successful operation

/**
 * WitnessAsyncNotify RPC message implementation for MS-SWN specification.
 * This message is used to receive asynchronous notifications from the witness service.
 */
public class WitnessAsyncNotifyMessage extends WitnessRpcMessage {

    // Input parameters for WitnessAsyncNotify
    private byte[] contextHandle;

OkHttp 2 is designed around a new API that is true to HTTP, with classes for
requests, responses, headers, and calls. It uses modern Java patterns like
immutability and chained builders. The API now offers asynchronous callbacks
in addition to synchronous blocking calls.

#### API Changes

 *  **New Request and Response types,** each with their own builder. There's also
    a `RequestBody` class to write the request body to the network and a

최신 파이썬 버전은 **“코루틴”**이라고 하는 것을 사용하는 **“비동기 코드”**를 **`async` 및 `await`** 문법과 함께 지원합니다.

아래 섹션들에서 해당 문장을 부분별로 살펴보겠습니다:

* **비동기 코드**
* **`async`와 `await`**
* **코루틴**

## 비동기 코드 { #asynchronous-code }

비동기 코드는 언어 💬 가 코드의 어느 한 부분에서 컴퓨터/프로그램 🤖 에게, 어느 시점에는 어딘가에서 *다른 무언가*가 끝날 때까지 기다려야 한다고 말할 수 있는 방법이 있다는 의미입니다. 그 *다른 무언가*를 "slow-file" 📝 이라고 해보겠습니다.

따라서 그 시간 동안 컴퓨터는 "slow-file" 📝 이 끝나는 동안 다른 작업을 하러 갈 수 있습니다.
