                                    <tbody>

创建 `get_current_user` 依赖项。

还记得依赖项支持子依赖项吗？

`get_current_user` 使用 `oauth2_scheme` 作为依赖项。

与之前直接在路径操作中的做法相同，新的 `get_current_user` 依赖项从子依赖项 `oauth2_scheme` 中接收 `str` 类型的 `token`：

```Python hl_lines="25"
{!../../../docs_src/security/tutorial002.py!}
```

## 获取用户

`get_current_user` 使用创建的（伪）工具函数，该函数接收 `str` 类型的令牌，并返回 Pydantic 的 `User` 模型：

```Python hl_lines="19-22  26-27"

                                <table class="table table-bordered">
                                    <tbody>
                                    <tr>
                                        <th style="width: 25%"><la:message
                                                key="labels.file_auth_hostname"/></th>
                                        <td>${f:h(hostname)}<la:hidden property="hostname"/></td>

                                <table class="table table-bordered">
                                    <tbody>
                                    <tr>
                                        <th style="width: 25%"><la:message
                                                key="labels.webauth_hostname"/></th>
                                        <td>${f:h(hostname)}<la:hidden property="hostname"/></td>
