3. This `yield from` tells the function to iterate over that thing named `file_like`. And then, for each part iterated, yield that part as coming from this generator function.

    So, it is a generator function that transfers the "generating" work to something else internally.

   *
   * A push promise contains all the headers that pertain to a server-initiated request, and a
   * `promisedStreamId` to which response frames will be delivered. Push promise frames are sent as
   * a part of the response to `streamId`. The `promisedStreamId` has a priority of one greater than
   * `streamId`.
   *
   * @param streamId client-initiated stream ID.  Must be an odd number.

            // and the only FIR that we have for that PSI is an implicit invoke call, that means that

!!! info
    The additional header `WWW-Authenticate` with value `Bearer` we are returning here is also part of the spec.

    Any HTTP (error) status code 401 "UNAUTHORIZED" is supposed to also return a `WWW-Authenticate` header.

    In the case of bearer tokens (our case), the value of that header should be `Bearer`.

* Dem `username`.
* Dem `password`.
* Einem optionalen `scope`-Feld als langem String, bestehend aus durch Leerzeichen getrennten Strings.
* Einem optionalen `grant_type` („Art der Anmeldung“).

!!! tip "Tipp"
    Die OAuth2-Spezifikation *erfordert* tatsächlich ein Feld `grant_type` mit dem festen Wert `password`, aber `OAuth2PasswordRequestForm` erzwingt dies nicht.
