Если в запросе была строка запроса (query), она будет записана в лог фоновой задачей.

Затем другая фоновая задача, созданная в функции‑обработчике пути, запишет сообщение, используя path‑параметр `email`.

Класс `BackgroundTasks` приходит напрямую из [`starlette.background`](https://www.starlette.dev/background/).

## Basit HTTP Basic Auth { #simple-http-basic-auth }

* `HTTPBasic` ve `HTTPBasicCredentials` import edin.
* `HTTPBasic` kullanarak bir "`security` scheme" oluşturun.
* *path operation*’ınızda bir dependency ile bu `security`’yi kullanın.
* Bu, `HTTPBasicCredentials` tipinde bir nesne döndürür:
    * İçinde gönderilen `username` ve `password` bulunur.

Transition tiers can be added to MinIO using `mc admin tier add` command to associate a `gcs`, `s3` or `azure` bucket or prefix path on a bucket to the tier name.
Lifecycle transition rules can be applied to buckets (both versioned and un-versioned) by specifying the tier name defined above as the transition storage class for the lifecycle rule.

## Implementation

    these accessors will throw an `IllegalStateException` if the service has not yet been started.

 *  Breaking: Rename `RecordedRequest.path` to `RecordedRequest.target`. (This property is
    _sometimes_ a path, but it can also be a path and query, or a full URL.)

 *  Breaking: Decompose the `RecordedRequest.requestLine` into three properties, `method`, `target`,

                form.dictId = dictId;
            });
        }).renderWith(data -> {
            charMappingService.getCharMappingFile(dictId).ifPresent(file -> {
                RenderDataUtil.register(data, "path", file.getPath());
            }).orElse(() -> {
                throwValidationError(messages -> messages.addErrorsFailedToDownloadMappingFile(GLOBAL), this::asDictIndexHtml);
            });
        });
    }

```JSON

    "detail": [

**FastAPI** 內建一套強大且直覺的 **<dfn title="也稱為：元件、資源、提供者、服務、可注入項">依賴注入</dfn>** 系統。

它被設計為易於使用，使任何開發者都能輕鬆將其他元件與 **FastAPI** 整合。

## 什麼是「依賴注入」 { #what-is-dependency-injection }

在程式設計中，「依賴注入」的意思是：你的程式碼（此處指你的「路徑操作函式 (path operation functions)」）可以宣告它為了正常運作所需要的各種東西：也就是「依賴」。

接著，這個系統（此處是 **FastAPI**）會負責做任何必要的事，將這些所需的依賴提供給你的程式碼（「注入」依賴）。

當你需要以下情境時，這特別有用：

* 共享邏輯（相同的邏輯一次又一次地使用）。
* 共用資料庫連線。
* 強制套用安全性、驗證、角色要求等。
* 以及許多其他事情...
