### 使用你的标签

将 `tags` 参数和*路径操作*（以及 `APIRouter`）一起使用，将其分配给不同的标签：

```Python hl_lines="21  26"
{!../../docs_src/metadata/tutorial004.py!}
```

/// info | "信息"

### 标签顺序

每个标签元数据字典的顺序也定义了在文档用户界面显示的顺序。

created during iteration, that entry may be produced during the iteration or
may be skipped. The choice may vary for each entry created and from one
iteration to the next.

Open another terminal and upload a JPEG image into `images` bucket.

```
mc cp myphoto.jpg myminio/images
```

In the previous terminal, you will now see the operation that MinIO performs on Redis:

If you communicate with that *path operation* sending two HTTP headers like:

```
X-Token: foo
X-Token: bar

The response would be like:

        "bar",
        "foo"
    ]
}
