To exclude a query parameter from the generated OpenAPI schema (and thus, from the automatic documentation systems), set the parameter `include_in_schema` of `Query` to `False`:

Você teria **um único objeto `engine`** para todo o seu código se conectar ao mesmo banco de dados.

{* ../../docs_src/sql_databases/tutorial001_an_py310.py ln[14:18] hl[14:15,17:18] *}

Usar `check_same_thread=False` permite que o FastAPI use o mesmo banco de dados SQLite em diferentes threads. Isso é necessário, pois **uma única requisição** pode usar **mais de uma thread** (por exemplo, em dependências).

### 从 `root_path` 禁用自动服务器

如果不想让 **FastAPI** 包含使用 `root_path` 的自动服务器，则要使用参数 `root_path_in_servers=False`：

{* ../../docs_src/behind_a_proxy/tutorial004.py hl[9] *}

这样，就不会在 OpenAPI 概图中包含服务器了。
