### The resulting response { #the-resulting-response }

If the client requests `http://example.com/items/foo` (an `item_id` `"foo"`), that client will receive an HTTP status code of 200, and a JSON response of:

```JSON
{
  "item": "The Foo Wrestlers"
}
```

        try {
            // get a content
            final ClassicHttpResponse response = executeHttpClient(httpGet);
            httpEntity = response.getEntity();

            final int httpStatusCode = response.getCode();
            if (httpStatusCode == 200) {

                // check file size
                final Header contentLengthHeader = response.getFirstHeader("Content-Length");
                if (contentLengthHeader != null) {

import jcifs.internal.TreeConnectResponse;
import jcifs.internal.smb2.ServerMessageBlock2;
import jcifs.internal.smb2.ServerMessageBlock2Response;

Bu örnekte, client var olmayan bir ID ile bir item istediğinde, `404` status code’u ile bir exception raise edelim:

### Ortaya Çıkan Response { #the-resulting-response }

Client `http://example.com/items/foo` (bir `item_id` `"foo"`) isterse, HTTP status code olarak 200 ve şu JSON response’u alır:

```JSON
{
  "item": "The Foo Wrestlers"
}
```

    startsFirst.start()
    val endsFirst = buildRequestThread(secondRequest, secondResponseCode)
    endsFirst.start()
    endsFirst.join()
    // First response is still waiting.
    assertThat(firstResponseCode.get()).isEqualTo(0)
    // Second response is done.
    assertThat(secondResponseCode.get()).isEqualTo(200)
    latch.countDown()
    startsFirst.join()
    // And now it's done!

    /**
     * Constructs a new BatchRequestException with the specified message and results.
     *
     * @param <REQ> The type of the request
     * @param <REP> The type of the response
     * @param message The error message describing the batch operation failure
     * @param allResults List of results from all attempted requests in the batch
     */

If a client tries to send some **extra** data in the **query parameters**, they will receive an **error** response.

For example, if the client tries to send a `tool` query parameter with a value of `plumbus`, like:

```http
https://example.com/items/?limit=10&tool=plumbus
```

They will receive an **error** response telling them that the query parameter `tool` is not allowed:

```json
{
    "detail": [
        {

## Codes HTTP supplémentaires { #additional-status-codes_1 }

Si vous souhaitez renvoyer des codes HTTP supplémentaires en plus du code principal, vous pouvez le faire en renvoyant directement une `Response`, comme une `JSONResponse`, et en définissant directement le code HTTP supplémentaire.

    if isinstance(route.response_class, DefaultPlaceholder):
        current_response_class: type[Response] = route.response_class.value
    else:
        current_response_class = route.response_class
    assert current_response_class, "A response class is needed to generate OpenAPI"
    route_response_media_type: str | None = current_response_class.media_type
    if route.include_in_schema:

            if (sendException != null) {
                throw sendException;
            }
        }

        @Override
        protected void doRecv(Response response) throws IOException {
            if (recvException != null) {
                throw recvException;
            }
        }
