**FastAPI** n'est pas réellement une alternative à **Requests**. Leur cadre est très différent.

Il serait en fait plus courant d'utiliser Requests _à l'intérieur_ d'une application FastAPI.

Mais quand même, FastAPI s'est inspiré de Requests.

    inappropriate.

 *  New: `HttpUrl.get(String)` is an alternative to `HttpUrl.parse(String)` that throws an exception
    when the URL is malformed instead of returning null. Use this to avoid checking for null in
    situations where the input is known to be well-formed. We've also added `MediaType.get(String)`
    which is an exception-throwing alternative to `MediaType.parse(String)`.
