## Gereksinimler

FastAPI iki devin omuzları üstünde duruyor:

* Web tarafı için <a href="https://www.starlette.dev/" class="external-link" target="_blank">Starlette</a>.

## Kurulum

<div class="termy">

```console

if /i %SERVICE_CMD% == start goto doStart
if /i %SERVICE_CMD% == stop goto doStop
if /i %SERVICE_CMD% == manager goto doManagment
echo Unknown option "%SERVICE_CMD%"

:displayUsage
echo.
echo Usage: service.bat install^|remove^|start^|stop^|manager [SERVICE_ID]
goto:eof

:doStart
"%EXECUTABLE%" //ES//%SERVICE_ID% %LOG_OPTS%
if not errorlevel 1 goto started
echo Failed starting '%SERVICE_ID%' service

/// note | Détails techniques

Vous pouvez aussi utiliser `from starlette.responses import JSONResponse`.

**FastAPI** fournit le même objet `starlette.responses` que `fastapi.responses` juste par commodité pour le développeur. Mais la plupart des réponses disponibles proviennent directement de Starlette.

		case "Endpoint":
			z.Endpoint, err = dc.ReadString()
			if err != nil {
				err = msgp.WrapError(err, "Endpoint")
				return
			}
		case "Started":
			z.Started, err = dc.ReadTime()
			if err != nil {
				err = msgp.WrapError(err, "Started")
				return

		case "LastUpdate":
			z.LastUpdate, err = dc.ReadTime()

				err = msgp.WrapError(err, "LastUpdate")
				return

In contrast to a "**container image**" that is the stored static contents, a "**container**" normally refers to the running instance, the thing that is being **executed**.

When the **container** is started and running (started from a **container image**) it could create or change files, environment variables, etc. Those changes will exist only in that container, but would not persist in the underlying container image (would not be saved to disk).

Ese código de estado se usará en el response y se añadirá al esquema de OpenAPI.
