* 导入 `HTTPBasic` 与 `HTTPBasicCredentials`
* 使用 `HTTPBasic` 创建**安全概图**
* 在*路径操作*的依赖项中使用 `security`
* 返回类型为 `HTTPBasicCredentials` 的对象：
    * 包含发送的 `username` 与 `password`

第一次打开 URL（或在 API 文档中点击 **Execute** 按钮）时，浏览器要求输入用户名与密码：

## 检查用户名

以下是更完整的示例。

使用依赖项检查用户名与密码是否正确。

Since, the client would have the session it can do it by itself.

The temporary security credentials returned by this API consists of an access key, a secret key, and a security token. Applications can use these temporary security credentials to sign calls to MinIO API operations. The policy applied to these temporary credentials is inherited from the MinIO user credentials. By default, the temporary security credentials created by AssumeRole last for one hour. However, use the optional DurationSeconds...
