### 未激活用户 { #inactive-user }

测试未激活用户，输入以下信息，进行身份验证：

用户名：`alice`

密码：`secret2`

然后，执行 `/users/me` 路径的 `GET` 操作。

显示下列**未激活用户**错误信息：

```JSON
{

```plaintext

```

這意味著系統現在會首先在以下目錄中查找程式：

```plaintext
C:\Users\user\code\awesome-project\.venv\Scripts
```

然後再在其他目錄中查找。

因此，當你在終端機中輸入 `python` 時，系統會在以下目錄中找到 Python 程式：

```plaintext
C:\Users\user\code\awesome-project\.venv\Scripts\python
```

並使用這個。

Redirection from OpenID Provider

To login to MinIO, the user first loads the MinIO console on their browser, and selects the OpenID Provider they wish to use (the `MINIO_IDENTITY_OPENID_DISPLAY_NAME` value is shown here). The user is then redirected to the OpenID provider's login page and performs necessary login actions (e.g. entering credentials, responding to MFA authentication challenges, etc). After successful login, the user is redirected back to the MinIO console. This redirect URL is...

### Cache the OpenAPI schema { #cache-the-openapi-schema }

You can use the property `.openapi_schema` as a "cache", to store your generated schema.

That way, your application won't have to generate the schema every time a user opens your API docs.

It will be generated only once, and then the same cached schema will be used for the next requests.
