By considering these concepts, you will be able to **evaluate and design** the best way to deploy **your own APIs**.

In the next chapters, I'll give you more **concrete recipes** to deploy FastAPI applications.

But for now, let's check these important **conceptual ideas**. These concepts also apply to any other type of web API. 💡

## Security - HTTPS { #security-https }

```console
$ fastapi run main.py --forwarded-allow-ips="*" --root-path /api/v1

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

### 응답 확인하기 { #check-the-responses }

이제 Uvicorn의 포트로 된 URL인 [http://127.0.0.1:8000/app](http://127.0.0.1:8000/app)로 접속하면 정상 응답을 볼 수 있습니다:

```JSON
{
    "message": "Hello World",
    "root_path": "/api/v1"
}
```

		}
	}
	return i
}

// Does all errors indicate we need to initialize all disks?.
func shouldInitErasureDisks(errs []error) bool {
	return countErrs(errs, errUnformattedDisk) == len(errs)
}

// Check if unformatted disks are equal to 50%+1 of all the drives.
func quorumUnformattedDisks(errs []error) bool {
	return countErrs(errs, errUnformattedDisk) >= (len(errs)/2)+1
}

            /*
             * TODO(cpovirk): Replace these two statements with one (`N element =
             * requireNonNull(top.next())`) once our checker supports it.

        .url(server.url("/"))
        .method("POST", requestBody1)
        .build()
    val response1 = client.newCall(request1).execute()
    assertThat(response1.code).isEqualTo(200)

    // Call 2: check for the absence of a deadline on the request body.
    val requestBody2: RequestBody =
      object : RequestBody() {
        override fun contentType(): MediaType = "text/plain".toMediaType()

func hashOrder(key string, cardinality int) []int {
	if cardinality <= 0 {
		// Returns an empty int slice for cardinality < 0.
		return nil
	}

	nums := make([]int, cardinality)
	keyCrc := crc32.Checksum([]byte(key), crc32.IEEETable)

	start := int(keyCrc % uint32(cardinality))
	for i := 1; i <= cardinality; i++ {
		nums[i-1] = 1 + ((start + i) % cardinality)
	}
	return nums
}

var (

    /**

     *
     * @return an {@link Optional} containing true if strict checksum verification is enabled, false if not, or empty if not specified

    @Nonnull
    Optional<Boolean> strictChecksums();

## More information about OpenAPI responses { #more-information-about-openapi-responses }

To see what exactly you can include in the responses, you can check these sections in the OpenAPI specification:

* [OpenAPI Responses Object](https://github.com/OAI/OpenAPI-Specification/blob/master/versions/3.1.0.md#responses-object), it includes the `Response Object`.

{* ../../docs_src/path_operation_configuration/tutorial005_py310.py hl[18] *}

/// info | 情報

`response_description`は具体的にレスポンスを参照し、`description`は*path operation*全般を参照していることに注意してください。

///

/// check | 確認

OpenAPIは*path operation*ごとにレスポンスの説明を必要としています。

そのため、それを提供しない場合は、**FastAPI** が自動的に「成功のレスポンス」を生成します。

Зверніть увагу, що ви передаєте не сам маршрутизатор (`invoices_callback_router`) у `callback=`, а атрибут `.routes`, тобто `invoices_callback_router.routes`.
