# Attachments

> 说明如何在 Laravel Copilot SDK 中附加文件、目录、选中范围和 Blob 并发送 prompt。

## File attachments

按如下方式以数组形式指定文件或目录。

```php theme={null}
use Revolution\Copilot\Facades\Copilot;

$attachments = [
    [
        'type' => 'file',
        'path' => '/path/to/file.php',
        'displayName' => 'My File',// 可省略
    ],
    [
        'type' => 'directory',
        'path' => '/path/to/dir/',
        'displayName' => 'dir',// 可省略
    ],
    [
        'type' => 'selection',
        'filePath' => '/path/to/file.php',
        'displayName' => 'My File',// 这里不可省略
        'selection' => [
            'start' => ['line' => 1, 'character' => 10],
            'end' => ['line' => 5, 'character' => 10],
        ],
        'text' => '...',
    ],
    [
        'type' => 'blob',
        'data' => base64_encode(file_get_contents('/path/to/image.png')),
        'mimeType' => 'image/png',
        'displayName' => 'screenshot.png',// 可省略
    ],
];

$response = Copilot::run(prompt: '...', attachments: $attachments);
```

记住这样的格式比较困难，因此我们准备了辅助工具方便你使用。

```php theme={null}
use Revolution\Copilot\Facades\Copilot;
use Revolution\Copilot\Support\Attachment;

$attachments = [
    Attachment::file(path: '/path/to/file.php', displayName: 'My File'),
    Attachment::directory(path: '/path/to/dir/', displayName: 'dir'),
    Attachment::selection(filePath: '/path/to/file.php', displayName: 'My File', selection: ['start' => ['line' => 1, 'character' => 10], 'end' => ['line' => 5, 'character' => 10]], text: '...'),
    Attachment::blob(data: base64_encode(file_get_contents('/path/to/image.png')), mimeType: 'image/png', displayName: 'screenshot.png'),
];

$response = Copilot::run(prompt: '...', attachments: $attachments);
```

## Blob attachments

`blob` 类型用于以内联方式附加 Base64 编码的数据。可以在没有磁盘 I/O 的情况下直接发送图片等二进制数据。

```php theme={null}
use Revolution\Copilot\Support\Attachment;

// 将图片文件 Base64 编码后附加
$attachment = Attachment::blob(
    data: base64_encode(file_get_contents('/path/to/image.png')),
    mimeType: 'image/png',
    displayName: 'screenshot.png',
);
```

<Info>
  `selection` 在官方 SDK 中尚无文档，因此详情不明。`github_reference` 也由于官方信息不足，将在后续支持。
