# JSON with Bytes as Base64 { #json-with-bytes-as-base64 }

If your app needs to receive and send JSON data, but you need to include binary data in it, you can encode it as base64.

## Base64 vs Files { #base64-vs-files }

Consider first if you can use [Request Files](../tutorial/request-files.md) for uploading binary data and [Custom Response - FileResponse](./custom-response.md#fileresponse--fileresponse-) for sending binary data, instead of encoding it in JSON.

programs, this change should be a no-op, or result in a performance improvement.
In rare cases, programs that do not benefit from connection reuse might
experience performance degradation if they had been improperly allowing an
excessive amount of idle connections to linger; usually by setting
[Transport.MaxIdleConns] to `0` or using different [Client]s for different
requests, thereby bypassing [Transport.MaxIdleConns] limit. In these cases,

    /**
     * Default maximum number of receive credits
     */
    public static final int DEFAULT_RECEIVE_CREDIT_MAX = 255;

    /**
     * Default target number of send credits
     */
    public static final int DEFAULT_SEND_CREDIT_TARGET = 32;

    /**
     * Default maximum receive size (8KB)
     */
    public static final int DEFAULT_MAX_RECEIVE_SIZE = 8192;

    /**

In your WebSocket route you can `await` for messages and send messages.

You can receive and send binary, text, and JSON data.

## Try it { #try-it }

Put your code in a file `main.py` and then run your application:

<div class="termy">

```console
$ fastapi dev

// WalkDirOptions provides options for WalkDir operations.
type WalkDirOptions struct {
	// Bucket to scanner
	Bucket string

	// Directory inside the bucket.
	BaseDir string

	// Do a full recursive scan.
	Recursive bool

	// ReportNotFound will return errFileNotFound if all disks reports the BaseDir cannot be found.
	ReportNotFound bool

	// FilterPrefix will only return results with given prefix within folder.

            addPluginGroup(pluginGroup);
        }

        return this;
    }

    @Override
    public MavenExecutionRequest setRecursive(boolean recursive) {
        this.recursive = recursive;

        return this;
    }

    // calculated from request attributes.
    private ProjectBuildingRequest projectBuildingRequest;

    @Override

            RdmaMemoryRegion recvRegion = bufferManager.getReceiveRegion();
            assertNotNull(recvRegion, "Receive region should not be null");
            assertTrue(recvRegion.getSize() > 0, "Receive region should have positive size");
            assertNotNull(recvRegion.getBuffer(), "Receive region buffer should not be null");

            // Test buffer pooling statistics

У `Request` є атрибут `request.scope` - це просто Python `dict`, що містить метадані, пов'язані із запитом.

Також `Request` має `request.receive` - це функція для «отримання» тіла запиту.

`scope` `dict` і функція `receive` є частиною специфікації ASGI.

І саме ці дві сутності - `scope` та `receive` - потрібні для створення нового екземпляра `Request`.
