To see the difference, imagine the following story about burgers:

### Concurrent Burgers

You go with your crush to get fast food, you stand in line while the cashier takes the orders from the people in front of you. 😍

Then it's your turn, you place your order of 2 very fancy burgers for your crush and you. 🍔🍔

    assertThat(bodyToHex(body)).isEqualTo("616263")
    assertThat(bodyToHex(body), "Retransmit body").isEqualTo("616263")
  }

  /** Common verbs used for apis such as GitHub, AWS, and Google Cloud.  */
  @Test
  fun crudVerbs() {
    val contentType = "application/json".toMediaType()
    val body = "{}".toRequestBody(contentType)

    val get = Request.Builder().url("http://localhost/api").get().build()

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.

    이러한 세부 사항은 구현에 따라 다릅니다.

    OAuth2의 경우 문자열일 뿐입니다.

Benutzer** erfahren Sie mehr darüber, wie Sie OAuth2-„Scopes“ für ein feingranuliertes Berechtigungssystem verwenden, das denselben Standards folgt. OAuth2 mit Scopes ist der Mechanismus, der von vielen großen Authentifizierungsanbietern wie Facebook, Google, GitHub, Microsoft, Twitter, usw. verwendet wird, um Drittanbieteranwendungen zu autorisieren, im Namen ihrer Benutzer mit ihren APIs zu interagieren....

* `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
    In OAuth2 ist ein „Scope“ nur ein String, der eine bestimmte erforderliche Berechtigung deklariert.

    Es spielt keine Rolle, ob er andere Zeichen wie `:` enthält oder ob es eine URL ist.

* `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.

!!! info
    In OAuth2 a "scope" is just a string that declares a specific permission required.

    It doesn't matter if it has other characters like `:` or if it is a URL.

#### Optimizations

A naive implementation would simply regenerate all resources, of all subscribed types, for each client, on any configuration change. However, this scales poorly. As a result, we have many levels of optimizations to avoid doing this work.
