A **`Session`** is what stores the **objects in memory** and keeps track of any changes needed in the data, then it **uses the `engine`** to communicate with the database.

We will create a FastAPI **dependency** with `yield` that will provide a new `Session` for each request. This is what ensures that we use a single session per request. 🤓

Then we create an `Annotated` dependency `SessionDep` to simplify the rest of the code that will use this dependency.

    }

    /**
     * Gets the OpenID Connect token server URL.
     *
     * @return the token server URL
     */
    protected String getOicTokenServerUrl() {
        return ComponentUtil.getSystemProperties().getProperty(OIC_TOKEN_SERVER_URL, "https://accounts.google.com/o/oauth2/token");
    }

    /**
     * Gets the OpenID Connect redirect URL.
     *

        // Given
        int fid = 123;
        long lastWriteTime = System.currentTimeMillis();

        // When
        SmbComClose smbComClose = new SmbComClose(config, fid, lastWriteTime);

        // Then
        assertEquals(ServerMessageBlock.SMB_COM_CLOSE, smbComClose.getCommand());
        // Private fields are not directly accessible, but we can check their effect in other methods.
    }

    /**

For example:

{* ../../docs_src/conditional_openapi/tutorial001.py hl[6,11] *}

Here we declare the setting `openapi_url` with the same default of `"/openapi.json"`.

And then we use it when creating the `FastAPI` app.

Then you could disable OpenAPI (including the UI docs) by setting the environment variable `OPENAPI_URL` to the empty string, like:

<div class="termy">

```console
$ OPENAPI_URL= uvicorn main:app

if [ $siteb_count -ne 0 ]; then

Например, чтобы объявить заголовок `X-Token`, который может появляться более одного раза, вы можете написать:

{* ../../docs_src/header_params/tutorial003_an_py310.py hl[9] *}

Если вы взаимодействуете с этой *операцией пути*, отправляя два HTTP-заголовка, таких как:

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

Ответ был бы таким:

```JSON
{
    "X-Token values": [
        "bar",
        "foo"
    ]
}
