### 运行 { #run-it }

用下面的命令运行服务器：

<div class="termy">

```console
$ fastapi dev

Não faz diferença. O **FastAPI** sabe o que fazer.

The behavior behind the internal property can change at any time and without notice.
Internal properties MUST NOT be documented in public documentation.

As a *secondary aspect*, property names can carry **feature-stability** information of the features they represent.
As features progress through the lifecycle of early prototype, incubation, and stabilization, their corresponding properties may also be updated.

    return {"item_id": item_id, "q": q}

### Run it

Run the server with:

<div class="termy">

```console
$ fastapi dev

@app.get("/items/{item_id}")
async def read_item(item_id: int, q: str | None = None):
    return {"item_id": item_id, "q": q}
```

### 運行 { #run-it }

使用以下指令運行伺服器：

<div class="termy">

```console
$ fastapi dev

      future = null;
      while (next != null) {
        @RetainedLocalRef Listener curr = next;
        next = next.next;
        /*
         * requireNonNull is safe because the listener stack never contains TOMBSTONE until after
         * clearListeners.
         */
        Runnable task = requireNonNull(curr.task);
        if (task instanceof DelegatingToFuture) {
