## Özel Bir `Response` Döndürme { #returning-a-custom-response }

Yukarıdaki örnek ihtiyaç duyduğunuz tüm parçaları gösteriyor, ancak henüz çok kullanışlı değil. Çünkü `item`'ı zaten doğrudan döndürebilirdiniz ve **FastAPI** varsayılan olarak onu sizin için bir `JSONResponse` içine koyup `dict`'e çevirirdi vb.

Şimdi bunu kullanarak nasıl özel bir response döndürebileceğinize bakalım.

// returned by text/scanner.Scanner, plus a couple of extra values.
type ScanToken rune

                    this.expiration = -1;
                } else {
                    this.expiration = System.currentTimeMillis() + this.transportContext.getConfig().getSoTimeout();
                }

                T chainedResponse;

Remarquez que les *chemins d'accès* définissent les modèles qu’ils utilisent pour le payload de requête et le payload de réponse, en utilisant les modèles `Item` et `ResponseMessage`.

### Documentation de l’API { #api-docs }

Si vous allez sur `/docs`, vous verrez qu’elle contient les **schémas** pour les données à envoyer dans les requêtes et reçues dans les réponses :

                boolean first = true;
                for (final SuggestItem item : suggestResponse.getItems()) {
                    if (!first) {
                        buf.append(',');
                    }
                    first = false;

                    buf.append("{\"text\":\"").append(StringEscapeUtils.escapeJson(item.getText())).append('\"');
                    buf.append(",\"labels\":[");

    takeIndex = inc(takeIndex);
    --count;
    return x;
  }

  /**
   * Utility for remove and iterator.remove: Delete item at position i. Call only when occupying
   * monitor.
   */
  void removeAt(int i) {
    E[] items = this.items;
    // if removing front item, just advance
    if (i == takeIndex) {
      items[takeIndex] = null;
      takeIndex = inc(takeIndex);
    } else {

    try:
        yield db
    finally:
        db.close()


DBDep = Annotated[DBSession, Depends(get_db)]


@app.get("/items/")
async def read_items(db: DBDep):
    return db.query(Item).all()
```

Use the scope `"function"` when they should run the exit code after the response data is generated but before the response is sent back to the client.

```python
from typing import Annotated

        String expectedDescr = "WrLeh\u0000B13BWz\u0000";
        byte[] expectedDescrBytes = expectedDescr.getBytes("ASCII");
        byte[] actualDescrBytes = new byte[expectedDescrBytes.length];
        System.arraycopy(dst, 2, actualDescrBytes, 0, expectedDescrBytes.length);
        assertArrayEquals(expectedDescrBytes, actualDescrBytes);

        // Verify level (0x0001 - 2 bytes)

    }

    private MessageBuilder builder() {
        return messageBuilderFactory.builder();
    }

    private void logStats(MavenSession session) {
        infoLine('-');

        long finish = System.currentTimeMillis();

        long time = finish - session.getRequest().getStartTime().getTime();

        String wallClock = session.getRequest().getDegreeOfConcurrency() > 1 ? " (Wall Clock)" : "";
