如果没有接收到 HTTP 基础授权，就返回 HTTP 401 `"Unauthorized"` 错误。

并返回响应头 `WWW-Authenticate`，其值为 `Basic`，以及可选的 `realm` 参数。

HTTP 基础授权让浏览器显示内置的用户名与密码提示。

输入用户名与密码后，浏览器会把它们自动发送至请求头。

## 简单的 HTTP 基础授权 { #simple-http-basic-auth }

* 导入 `HTTPBasic` 与 `HTTPBasicCredentials`
* 使用 `HTTPBasic` 创建**安全方案**
* 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`

 * they could be resolved from a local repository - I think we need a simple dependency model here
 * that is more mercury related and not Maven related i.e. no POMs - workspace resolver - we need
 * tools to pre-populate this repository

    void testGetters() {
        // Simple test for getter methods

The most common case would be [returning a Response directly as explained later in the advanced docs](../advanced/response-directly.md).

{* ../../docs_src/response_model/tutorial003_02_py310.py hl[8,10:11] *}

This simple case is handled automatically by FastAPI because the return type annotation is the class (or a subclass of) `Response`.
