But if you want to use `async` / `await` without FastAPI, you can do it as well.

### Write your own async code

            bytesRead = source.read(sink, byteCount)
          } catch (e: IOException) {
            if (!cacheRequestClosed) {
              cacheRequestClosed = true
              cacheRequest.abort() // Failed to write a complete cache response.
            }
            throw e
          }

          if (bytesRead == -1L) {
            if (!cacheRequestClosed) {
              cacheRequestClosed = true

    taskFaker.runTasks()
  }

  private fun connectHttp2(
    peer: MockHttp2Peer,
    realConnection: RealConnection,
    maxConcurrentStreams: Int,

    // Write the mocking script.
    val settings1 = Settings()
    settings1[Settings.MAX_CONCURRENT_STREAMS] = maxConcurrentStreams
    peer.sendFrame().settings(settings1)
    peer.acceptFrame() // ACK

사양에는 클라이언트가 다른 폼 필드 "`scope`"를 보낼 수 있다고 나와 있습니다.

폼 필드 이름은 `scope`(단수형)이지만 실제로는 공백으로 구분된 "범위"가 있는 긴 문자열입니다.

각 "범위"는 공백이 없는 문자열입니다.

일반적으로 특정 보안 권한을 선언하는 데 사용됩니다. 다음을 봅시다:

* `users:read` 또는 `users:write`는 일반적인 예시입니다.
* `instagram_basic`은 페이스북/인스타그램에서 사용합니다.
* `https://www.googleapis.com/auth/drive`는 Google에서 사용합니다.

!!! 정보
    OAuth2에서 "범위"는 필요한 특정 권한을 선언하는 문자열입니다.

    `:`과 같은 다른 문자가 있는지 또는 URL인지는 중요하지 않습니다.

Jeder „Scope“ ist nur ein String (ohne Leerzeichen).

Diese werden normalerweise verwendet, um bestimmte Sicherheitsberechtigungen zu deklarieren, zum Beispiel:

* `users:read` oder `users:write` sind gängige Beispiele.
* `instagram_basic` wird von Facebook / Instagram verwendet.
* `https://www.googleapis.com/auth/drive` wird von Google verwendet.

!!! info

Each "scope" is just a string (without spaces).

They are normally used to declare specific security permissions, for example:

* `users:read` or `users:write` are common examples.
* `instagram_basic` is used by Facebook / Instagram.
* `https://www.googleapis.com/auth/drive` is used by Google.
