# Extendendo o OpenAPI { #extending-openapi }

Existem alguns casos em que pode ser necessário modificar o esquema OpenAPI gerado.

Nesta seção, você verá como fazer isso.

## O processo normal { #the-normal-process }

O processo normal (padrão) é o seguinte:

Uma aplicação (instância) do `FastAPI` possui um método `.openapi()` que deve retornar o esquema OpenAPI.

    public int getNodeType() throws UnknownHostException {
        checkData();
        return nodeType;
    }

    /**
     * Determines if this address in the process of being deleted.
     *
     * @return true if the address is being deleted, false otherwise
     * @throws UnknownHostException if the host cannot be resolved to find out.
     */

        final WebApiManager webApiManager = webApiManagerFactory.get((HttpServletRequest) request);
        if (webApiManager == null) {
            chain.doFilter(request, response);
        } else {
            webApiManager.process((HttpServletRequest) request, (HttpServletResponse) response, chain);
        }
    }

 * <pre>
 * {@code
 * FtpClient ftpClient = new FtpClient();
 * ftpClient.init(); // Initialize with configured parameters
 * ResponseData responseData = ftpClient.doGet("ftp://example.com/path/to/file.txt");
 * // Process the responseData
 * ftpClient.close(); // Close and release resources
 * }

* Return apiserver panics as 500 errors instead terminating the apiserver process. ([#68001](https://github.com/kubernetes/kubernetes/pull/68001), [@sttts](https://github.com/sttts))

Yukarıdaki uygulama, birden fazla WebSocket bağlantısına mesajları nasıl yönetip broadcast edeceğinizi göstermek için minimal ve basit bir örnektir.

Ancak her şey memory'de, tek bir list içinde yönetildiği için yalnızca process çalıştığı sürece ve yalnızca tek bir process ile çalışacaktır.

FastAPI ile kolay entegre olan ama Redis, PostgreSQL vb. tarafından desteklenen daha sağlam bir şeye ihtiyacınız varsa [encode/broadcaster](https://github.com/encode/broadcaster)'a göz atın.

// context_id is initialized with a dummy value and is later set when the worker
// is initialized (either locally or remotely). The context_id can change during
// the process lifetime although this should cause the worker to be
// reinitialized (e.g. cleared caches) as well.
TF_CAPI_EXPORT extern uint64_t TFE_GetContextId(TFE_Context* ctx);

І якщо ваш віддалений сервер або віртуальна машина має лише 3 GB RAM, спроба використати понад 4 GB призведе до проблем. 🚨

### Кілька процесів - приклад { #multiple-processes-an-example }

У цьому прикладі є **керівний процес** (Manager Process), який запускає і контролює два **процеси-працівники**.

Цей керівний процес, імовірно, саме і слухатиме **порт** на IP. І він передаватиме всю комунікацію процесам-працівникам.

Then, when it's your turn, you do actual "productive" work, you process the menu, decide what you want, get your crush's choice, pay, check that you give the correct bill or card, check that you are charged correctly, check that the order has the correct items, etc.
