Integrar otros proveedores de autenticación/autorización como Google, Facebook, X (Twitter), GitHub, etc. también es posible y relativamente fácil.

El problema más complejo es construir un proveedor de autenticación/autorización como esos, pero **FastAPI** te da las herramientas para hacerlo fácilmente, mientras hace el trabajo pesado por ti.

Para resolver esse mesmo problema, é provavelmente muito mais fácil usar o `body` em um manipulador personalizado para `RequestValidationError` ([Tratando Erros](../tutorial/handling-errors.md#use-the-requestvalidationerror-body){.internal-link target=_blank}).

- kube- and cloud-controller-manager can now listen on ports up to 65535 rather than 32768, solving problems with operating systems that request these higher ports.. ([#65860](https://github.com/kubernetes/kubernetes/pull/65860), [@sttts](https://github.com/sttts))

    `@Deprecated` APIs will remain (again, unless they are `@Beta`). We have no
    plans to start removing things again, but officially, we're leaving our
    options open in case of surprises (like, say, a serious security problem).

3.  Guava has one dependency that is needed for linkage at runtime:
    `com.google.guava:failureaccess:1.0.3`. It also has
    [some annotation-only dependencies][guava-deps], which we discuss in more

Il y a plusieurs frameworks REST pour Flask, mais après avoir investi du temps et du travail pour les étudier, j'ai
