# 特性

## FastAPI 特性

**FastAPI** 提供了以下内容：

### 建立在開放標準的基礎上

* 使用 <a href="https://github.com/OAI/OpenAPI-Specification" class="external-link" target="_blank"><strong>OpenAPI</strong></a> 來建立 API，包含<abbr title="path，也被叫做: endpoints, routes">路徑</abbr><abbr title="也叫做 HTTP 方法，例如 POST, GET, PUT, DELETE">操作</abbr>、參數、請求內文、安全性等聲明。

        public String toString() {
            return String.format(
                    "PoolHealthMetrics[active=%d, nonPooled=%d, tracked=%d, max=%d, "
                            + "healthChecks=%d, failed=%d, removed=%d, endpoints=%d, "
                            + "healthCheckEnabled=%s, proactiveEnabled=%s, utilization=%.2f%%, successRate=%.2f%%]",

## Another module with `APIRouter` { #another-module-with-apirouter }

Let's say you also have the endpoints dedicated to handling "items" from your application in the module at `app/routers/items.py`.

You have *path operations* for:

* `/items/`
* `/items/{item_id}`

=== ":material-language-kotlin: Kotlin"
    ```kotlin
      private val client = OkHttpClient()

      fun run() {
        // Use the imgur image upload API as documented at https://api.imgur.com/endpoints/image
        val requestBody = MultipartBody.Builder()
            .setType(MultipartBody.FORM)
            .addFormDataPart("title", "Square Logo")
            .addFormDataPart("image", "logo-square.png",

Pero en casos reales obtendrás mejores resultados usando las [utilidades de Seguridad](security/index.md){.internal-link target=_blank} integradas.

///

## Otro módulo con `APIRouter`

Digamos que también tienes los endpoints dedicados a manejar "items" de tu aplicación en el módulo `app/routers/items.py`.

Tienes *path operations* para:

* `/items/`
* `/items/{item_id}`

Es toda la misma estructura que con `app/routers/users.py`.

///

## Outro módulo com `APIRouter`

Digamos que você também tenha os endpoints dedicados a manipular "itens" do seu aplicativo no módulo em `app/routers/items.py`.

Você tem *operações de rota* para:

* `/items/`
* `/items/{item_id}`

É tudo a mesma estrutura de `app/routers/users.py`.

## FastAPIの機能

**FastAPI** は以下の機能をもちます:

### オープンスタンダード準拠

* API作成のための<a href="https://github.com/OAI/OpenAPI-Specification" class="external-link" target="_blank"><strong>OpenAPI</strong></a>。これは、<abbr title="also known as: endpoints, routes">path</abbr> <abbr title="also known as HTTP methods, as POST, GET, PUT, DELETE">operations</abbr>の宣言、パラメータ、ボディリクエスト、セキュリティなどを含んでいます。

Les routes sont déclarées à un seul endroit, en utilisant des fonctions déclarées à d'autres endroits (au lieu
d'utiliser des décorateurs qui peuvent être placés juste au-dessus de la fonction qui gère l'endpoint). Cette
