## Usa `CORSMiddleware` { #use-corsmiddleware }

Puedes configurarlo en tu aplicación **FastAPI** usando el `CORSMiddleware`.

* Importa `CORSMiddleware`.
* Crea una lista de orígenes permitidos (como strings).
* Agrégalo como un "middleware" a tu aplicación **FastAPI**.

También puedes especificar si tu backend permite:

* Credenciales (headers de autorización, cookies, etc).

                    throw new SuggesterException("Request timeout. time:" + time + " unit:" + unit.name());
                }
                if (error != null) {
                    throw new SuggesterException("An error occurred during the deferred computation.", error);
                }
                return response;
            } catch (final InterruptedException e) {
                throw new InterruptedRuntimeException(e);
            }

Then I contributed to it, to make it fully compliant with JSON Schema, to support different ways to define constraint declarations, and to improve editor support (type checks, autocompletion) based on the tests in several editors.

During the development, I also contributed to [**Starlette**](https://www.starlette.dev/), the other key requirement.

## Development { #development }

### Existing object replication

/// info

Note that the `TestClient` receives data that can be converted to JSON, not Pydantic models.

If you have a Pydantic model in your test and you want to send its data to the application during testing, you can use the `jsonable_encoder` described in [JSON Compatible Encoder](encoder.md).

///

## Run it { #run-it }

After that, you just need to install `pytest`.

* Vary the problem input size with `@Param`.
* Use the integrated profilers in JMH to dig deeper if benchmark results to not match your hypotheses:
    * Add `-prof gc` to the options to check whether the garbage collector runs during a microbenchmarks and skews
   your results. If so, try to force a GC between runs (`-gc true`) but watch out for the caveats.

모두 재사용 가능한 도구와 컴포넌트로 만들어져 있어, 여러분의 시스템, 데이터 저장소, 관계형 및 NoSQL 데이터베이스 등과 쉽게 통합할 수 있습니다.

### 의존성 주입 { #dependency-injection }

FastAPI는 사용하기 매우 쉽지만, 매우 강력한 <dfn title='또한 다음으로도 불림: "컴포넌트", "자원", "서비스", "제공자"'><strong>의존성 주입</strong></dfn> 시스템을 포함하고 있습니다.

* 의존성도 의존성을 가질 수 있어, 의존성의 계층 또는 **의존성의 "그래프"**를 생성합니다.
* 모든 것이 프레임워크에 의해 **자동으로 처리됩니다**.
* 모든 의존성은 요청에서 데이터를 요구할 수 있으며, **경로 처리** 제약과 자동 문서화를 강화할 수 있습니다.

     * Maven-Resolver without involving Maven Core and related things.
     * <p>
     * This type registry is NOT used by Maven Core: Maven replaces it during Session creation with a type registry
     * that supports extending it (i.e. via Maven Extensions).
     * <p>
     * Important: this "static" list of types should be in-sync with core provided types.
