Wenn Sie mit dieser *Pfadoperation* kommunizieren und zwei HTTP-Header senden, wie:

```
X-Token: foo

```

Dann wäre die <abbr title="Response – Antwort: Daten, die der Server zum anfragenden Client zurücksendet">Response</abbr>:

This property is sometimes referred to as DRF-SC: data-race-free programs
execute in a sequentially consistent manner.

<p>
While programmers should write Go programs without data races,
there are limitations to what a Go implementation can do in response to a data race.
An implementation may always react to a data race by reporting the race and terminating the program.

   * This test is for a case where two Service.Listener callbacks for the same service would call
   * transitionService in the wrong order due to a race. Due to the fact that it is a race this test
   * isn't guaranteed to expose the issue, but it is at least likely to become flaky if the race

# Sub-dependencies { #sub-dependencies }

You can create dependencies that have **sub-dependencies**.

They can be as **deep** as you need them to be.

**FastAPI** will take care of solving them.

## First dependency "dependable" { #first-dependency-dependable }

You could create a first dependency ("dependable") like:

Estos códigos de estado tienen un nombre asociado para reconocerlos, pero la parte importante es el número.

En breve:

* `100 - 199` son para "Información". Rara vez los usas directamente. Los responses con estos códigos de estado no pueden tener un body.
* **`200 - 299`** son para responses "Exitosos". Estos son los que usarías más.
