Dans OAuth2, un « scope » est simplement une chaîne qui déclare une permission spécifique requise.

Peu importe s’il contient d’autres caractères comme `:` ou si c’est une URL.

Ces détails dépendent de l’implémentation.

                case FAILED:

                case NO_IMAGE:
                    if (logger.isDebugEnabled()) {

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;
      @SuppressWarnings("unused") // https://errorprone.info/bugpattern/FutureReturnValueIgnored
      Future<?> possiblyIgnoredError =
          threadPool.submit(
              () -> {
                cache.getUnchecked(s);
                computedCount.incrementAndGet();

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

  private fun readAndWriteFrames() {
    check(socket == null)
    val socket = serverSocket!!.accept()!!
    this.socket = socket

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] *}
