## Simples e Poderoso { #simple-and-powerful }

Mesmo que o sistema hierárquico de injeção de dependência seja simples de definir e utilizar, ele ainda é bastante poderoso.

Você pode definir dependências que por sua vez definem suas próprias dependências.

### Специфические для OpenAPI `examples` { #openapi-specific-examples }

Ещё до того как **JSON Schema** поддержала `examples`, в OpenAPI была поддержка другого поля, также называемого `examples`.

Эти **специфические для OpenAPI** `examples` находятся в другой секции спецификации OpenAPI. Они находятся в **подробностях для каждой операции пути (обработчика пути)**, а не внутри каждого объекта Schema.

from fastapi import FastAPI
from pydantic import BaseModel, Field

app = FastAPI()


class Item(BaseModel):
    name: str = Field(examples=["Foo"])
    description: str | None = Field(default=None, examples=["A very nice Item"])
    price: float = Field(examples=[35.4])
    tax: float | None = Field(default=None, examples=[3.2])


@app.put("/items/{item_id}")
async def update_item(item_id: int, item: Item):

### OpenAPI 特定的 `examples` { #openapi-specific-examples }

在 **JSON Schema** 支援 `examples` 之前，OpenAPI 就已支援另一個同名的欄位 `examples`。

這個「OpenAPI 特定」的 `examples` 位於 OpenAPI 規範的另一個區塊：在每個「路徑操作」的詳細資訊中，而不是在各個 JSON Schema 內。

而 Swagger UI 早已支援這個欄位，因此你可以用它在文件 UI 中顯示不同的範例。

這個 OpenAPI 特定欄位 `examples` 的結構是一個包含「多個範例」的 `dict`（而非 `list`），每個範例都可包含會一併加入到 **OpenAPI** 的額外資訊。
