Et si vous consultez l’OpenAPI résultant (à `/openapi.json` dans votre API), vous verrez également votre extension comme partie du chemin d’accès spécifique :

```JSON hl_lines="22"
{
    "openapi": "3.1.0",
    "info": {
        "title": "FastAPI",
        "version": "0.1.0"
    },
    "paths": {
        "/items/": {
            "get": {
                "summary": "Read Items",

    CountDownLatch tasksFinished = new CountDownLatch(nTasks);
    for (int i = 0; i < nTasks; i++) {
      String s = "a" + i;
      @SuppressWarnings("unused") // https://errorprone.info/bugpattern/FutureReturnValueIgnored
      Future<?> possiblyIgnoredError =
          threadPool.submit(
              () -> {
                cache.getUnchecked(s);
                computedCount.incrementAndGet();

    CountDownLatch tasksFinished = new CountDownLatch(nTasks);
    for (int i = 0; i < nTasks; i++) {
      String s = "a" + i;

      Future<?> possiblyIgnoredError =
          threadPool.submit(

                computedCount.incrementAndGet();

    port = serverSocket!!.localPort
    executor.execute {
      try {
        readAndWriteFrames()
      } catch (e: IOException) {
        ******@****.***uietly()
        logger.info("${this@MockHttp2Peer} done: ${e.message}")

Y si ves el OpenAPI resultante (en `/openapi.json` en tu API), verás tu extensión como parte de la *path operation* específica también:

```JSON hl_lines="22"
{
    "openapi": "3.1.0",
    "info": {
        "title": "FastAPI",
        "version": "0.1.0"
    },
    "paths": {
        "/items/": {
            "get": {
                "summary": "Read Items",

### Use suas tags { #use-your-tags }

Use o parâmetro `tags` com suas *operações de rota* (e `APIRouter`s) para atribuí-los a diferentes tags:

{* ../../docs_src/metadata/tutorial004_py310.py hl[21,26] *}

`EmailStr`을 사용하려면 먼저 [`email-validator`](https://github.com/JoshData/python-email-validator)를 설치하세요.

[가상 환경](../virtual-environments.md)을 생성하고, 활성화한 다음 설치해야 합니다. 예를 들어:

```console
$ pip install email-validator

                    logger.info("Sent {} documents (process={}ms, send={}ms, size={}, {})", docList.size(), docList.getProcessingTime(),
                            systemHelper.getCurrentTimeAsLong() - execTime, MemoryUtil.byteCountToDisplaySize(docList.getContentSize()),
                            MemoryUtil.getMemoryUsageLog());
                } else {
