## **🏎**, FastAPI 🇳🇨

        """
        Add a *path operation* using an HTTP TRACE operation.

        ## Example

        ```python
        from fastapi import FastAPI

        app = FastAPI()

        @app.put("/items/{item_id}")
        def trace_item(item_id: str):
            return None
        ```

        return self.router.trace(
            path,

## Động lực nhiều hơn

Kiểm tra hàm này, nó đã có gợi ý kiểu dữ liệu:

```Python hl_lines="1"

```

Bởi vì trình soạn thảo biết kiểu dữ liệu của các biến, bạn không chỉ có được completion, bạn cũng được kiểm tra lỗi:

"Operacje" tutaj odnoszą się do jednej z "metod" HTTP.

Jedna z:

* `POST`
* `GET`
* `PUT`
* `DELETE`

...i te bardziej egzotyczne:

* `OPTIONS`
* `HEAD`
* `PATCH`
* `TRACE`

W protokole HTTP można komunikować się z każdą ścieżką za pomocą jednej (lub więcej) "metod".

Podczas tworzenia API zwykle używasz tych metod HTTP do wykonania określonej akcji.

Zazwyczaj używasz:
