* *路径*可以包含 [OpenAPI 3 表达式](https://github.com/OAI/OpenAPI-Specification/blob/master/versions/3.1.0.md#key-expression)（详见下文），可以使用带参数的变量，以及发送至您的 API 的原始请求的部分

### 回调路径表达式 { #the-callback-path-expression }

回调*路径*支持包含发送给您的 API 的原始请求的部分的 [OpenAPI 3 表达式](https://github.com/OAI/OpenAPI-Specification/blob/master/versions/3.1.0.md#key-expression)。

本例中是 `str`：

```Python

  // TODO(b/192446998): Remove this override after tools understand nullness better.
  public @Nullable V put(K key, @ParametricNullness V value) {
    return super.put(key, value);
  }

  @CanIgnoreReturnValue
  @Override
  @SuppressWarnings("RedundantOverride") // b/192446478: RedundantOverride ignores some annotations.
  // TODO(b/192446998): Remove this override after tools understand nullness better.

  * Use optimized image based on Jessie by default
  * Add support for Ubuntu Wily
  * Master is configured with automatic restart-on-failure, via CloudWatch
  * Bootstrap reworked to be more similar to GCE; better supports reboots/restarts
  * Use an elastic IP for the master by default
  * Experimental support for node spot instances (set NODE\_SPOT\_PRICE=0.05)

#### GCE

main channel of communication for contributors.  
There are some guidelines which will make applying PRs easier for us:
+ Create a topic branch from where you want to base your work (this is usually the master branch).
  Push your changes to a topic branch in your fork of the repository.
+ Make commits of logical units.
+ Respect the original code style: by using the same [codestyle][code-style],

		p.client.Transport = http.DefaultTransport
	}

	if p.oeConfig.TokenEndpoint == "" {
		return nil, errors.New("missing OpenID token endpoint")
	}

	if p.realm == "" {
		p.realm = "master" // default realm
	}

	return p, nil

* *path*에는 [OpenAPI 3 표현식](https://github.com/OAI/OpenAPI-Specification/blob/master/versions/3.1.0.md#key-expression)(자세한 내용은 아래 참고)이 포함될 수 있으며, 이를 통해 *여러분의 API*로 보내진 원래 요청의 파라미터와 일부 값을 변수로 사용할 수 있습니다.

### 콜백 경로 표현식 { #the-callback-path-expression }

콜백 *path*는 *여러분의 API*로 보내진 원래 요청의 일부를 포함할 수 있는 [OpenAPI 3 표현식](https://github.com/OAI/OpenAPI-Specification/blob/master/versions/3.1.0.md#key-expression)을 가질 수 있습니다.

이 경우, 다음 `str`입니다:

    return parentFile.isDescendentOf(directory)
  }

  /**
   * See FinalizationTester for discussion on how to best trigger GC in tests.
   * https://android.googlesource.com/platform/libcore/+/master/support/src/test/java/libcore/
   * java/lang/ref/FinalizationTester.java
   */
  @Throws(Exception::class)
  @JvmStatic
  fun awaitGarbageCollection() {
    Runtime.getRuntime().gc()
    Thread.sleep(100)

Fügen wir beispielsweise [ReDocs OpenAPI-Erweiterung zum Einbinden eines benutzerdefinierten Logos](https://github.com/Rebilly/ReDoc/blob/master/docs/redoc-vendor-extensions.md#x-logo) hinzu.

### Normales **FastAPI** { #normal-fastapi }

Schreiben Sie zunächst wie gewohnt Ihre ganze **FastAPI**-Anwendung:

Por ejemplo, vamos a añadir [la extensión OpenAPI de ReDoc para incluir un logo personalizado](https://github.com/Rebilly/ReDoc/blob/master/docs/redoc-vendor-extensions.md#x-logo).

### **FastAPI** normal { #normal-fastapi }

Primero, escribe toda tu aplicación **FastAPI** como normalmente:

        <mockk.version>1.14.9</mockk.version>
        <bytebuddy.version>1.18.7</bytebuddy.version>
        <jackson.version>2.21.2</jackson.version>
        <junit.version>6.0.3</junit.version>
        <dslContextParameter.branch>master</dslContextParameter.branch>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
