Go 1.22 disabled
[`ConnectionState.ExportKeyingMaterial`](/pkg/crypto/tls/#ConnectionState.ExportKeyingMaterial)
when the connection supports neither TLS 1.3 nor Extended Master Secret
(implemented in Go 1.21). It can be reenabled with the [`tlsunsafeekm`
setting](/pkg/crypto/tls/#ConnectionState.ExportKeyingMaterial).

Você pode criar as *operações de rotas* para esse módulo usando o `APIRouter`.

### Importar `APIRouter`

você o importa e cria uma "instância" da mesma maneira que faria com a classe `FastAPI`:

```Python hl_lines="1  3" title="app/routers/users.py"
{!../../docs_src/bigger_applications/app/routers/users.py!}
```

### *Operações de Rota* com `APIRouter`

E então você o utiliza para declarar suas *operações de rota*.

  optional SupplementalGroupsStrategyOptions supplementalGroups = 12;

  // fsGroup is the strategy that will dictate what fs group is used by the SecurityContext.
  optional FSGroupStrategyOptions fsGroup = 13;

  // readOnlyRootFilesystem when set to true will force containers to run with a read only root file
  // system.  If the container specifically requests to run with a non-read only root file system

* ...এবং অন্যান্য।

### ক্লাস হিসেবে টাইপস

আপনি একটি ভেরিয়েবলের টাইপ হিসেবে একটি ক্লাস ঘোষণা করতে পারেন।

ধরুন আপনার কাছে `Person` নামে একটি ক্লাস আছে, যার একটি নাম আছে:

```Python hl_lines="1-3"
{!../../docs_src/python_types/tutorial010.py!}
```

তারপর আপনি একটি ভেরিয়েবলকে `Person` টাইপের হিসেবে ঘোষণা করতে পারেন:

```Python hl_lines="6"
{!../../docs_src/python_types/tutorial010.py!}
```

## 创建 SQLAlchemy 部件

让我们转到文件`sql_app/database.py`。

### 导入 SQLAlchemy 部件

```Python hl_lines="1-3"
{!../../docs_src/sql_databases/sql_app/database.py!}
```

### 为 SQLAlchemy 定义数据库 URL地址

```Python hl_lines="5-6"
{!../../docs_src/sql_databases/sql_app/database.py!}
```
