# HTTP 基本認證 { #http-basic-auth }

在最簡單的情況下，你可以使用 HTTP Basic 認證。

在 HTTP Basic 認證中，應用程式會期待一個包含使用者名稱與密碼的標頭。

如果沒有接收到，會回傳 HTTP 401「Unauthorized」錯誤。

並回傳一個 `WWW-Authenticate` 標頭，其值為 `Basic`，以及可選的 `realm` 參數。

這會告訴瀏覽器顯示內建的使用者名稱與密碼提示視窗。

接著，當你輸入該使用者名稱與密碼時，瀏覽器會自動在標頭中送出它們。

## 簡單的 HTTP 基本認證 { #simple-http-basic-auth }

- 匯入 `HTTPBasic` 與 `HTTPBasicCredentials`。
- 使用 `HTTPBasic` 建立一個「`security` scheme」。
- 在你的*路徑操作*中以依賴的方式使用該 `security`。

For the simplest cases, you can use HTTP Basic Auth.

In HTTP Basic Auth, the application expects a header that contains a username and a password.

If it doesn't receive it, it returns an HTTP 401 "Unauthorized" error.

And returns a header `WWW-Authenticate` with a value of `Basic`, and an optional `realm` parameter.

That tells the browser to show the integrated prompt for a username and password.
