## Die Default-Exceptionhandler überschreiben { #override-the-default-exception-handlers }

**FastAPI** hat einige Default-Exceptionhandler.

Diese Handler sind dafür verantwortlich, die Default-JSON-Responses zurückzugeben, wenn Sie eine `HTTPException` `raise`n und wenn der Request ungültige Daten enthält.

	// Register distributed namespace lock routers.
	registerLockRESTHandlers(lockGrid)

	// Add lock grid to router
	router.Handle(grid.RouteLockPath, adminMiddleware(lockGrid.Handler(storageServerRequestValidate), noGZFlag, noObjLayerFlag))

	// Add grid to router
	router.Handle(grid.RoutePath, adminMiddleware(commonGrid.Handler(storageServerRequestValidate), noGZFlag, noObjLayerFlag))

## `Depends()`

Dependencies are handled mainly with the special function `Depends()` that takes a callable.

Here is the reference for it and its parameters.

You can import it directly from `fastapi`:

```python
from fastapi import Depends
```

::: fastapi.Depends
