然后在创建 `FastAPI` 应用时使用它。

接着，你可以通过把环境变量 `OPENAPI_URL` 设为空字符串来禁用 OpenAPI（包括文档 UI），例如：

<div class="termy">

```console
$ OPENAPI_URL= uvicorn main:app

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

</div>

然后如果你访问 `/openapi.json`、`/docs` 或 `/redoc`，就会得到一个 `404 Not Found` 错误，例如：

```JSON
{
    "detail": "Not Found"
}

const (
	arnPrefixArn        = "arn"
	arnPartitionMinio   = "minio"
	arnServiceIAM       = "iam"
	arnResourceTypeRole = "role"
)

// ARN - representation of resources based on AWS ARNs.
type ARN struct {
	Partition    string
	Service      string
	Region       string
	ResourceType string
	ResourceID   string
}

// Allows english letters, numbers, '.', '-', '_' and '/'. Starts with a

			Optional:    true,
			Type:        "csv",
		},
		config.HelpKV{
			Key:         apiRemoteTransportDeadline,
			Description: `set the deadline for API requests on remote transports while proxying between federated instances e.g. "2h"` + defaultHelpPostfix(apiRemoteTransportDeadline),
			Optional:    true,
			Type:        "duration",
		},
		config.HelpKV{
			Key:         apiListQuorum,

            // When: Decoding the value
            ndrShort.decode(mockBuffer);

            // Then: Should set the negative value directly (no masking on decode)
            verify(mockBuffer).dec_ndr_short();
            assertEquals(negativeValue, ndrShort.value);
        }

        @Test
        @DisplayName("Should decode large value correctly")

您可以接收和发送二进制、文本和 JSON 数据。

## 尝试一下 { #try-it }

将代码放在 `main.py`，然后运行你的应用程序：

<div class="termy">

```console
$ fastapi dev

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

</div>

在浏览器中打开 [http://127.0.0.1:8000](http://127.0.0.1:8000)。

您将看到一个简单的页面，如下所示：

<img src="/img/tutorial/websockets/image01.png">

您可以在输入框中输入消息并发送：

			throughputHighestPut = totalPut

			if doBreak {
				sendResult()
				break
			}

			for _, result := range results {
				if result.Error != "" {
					// Break out on errors.
					sendResult()
					return
				}
			}

			sendResult()
			if !opts.autotune {
				break
			}

			// Try with a higher concurrency to see if we get better throughput
