By declaring a *path operation function* parameter with the type being the `Request` **FastAPI** will know to pass the `Request` in that parameter.

/// tip

Note that in this case, we are declaring a path parameter beside the request parameter.

So, the path parameter will be extracted, validated, converted to the specified type and annotated with OpenAPI.

Wenn Sie eine zweiminütige Auffrischung benötigen, wie man Python-Typen verwendet (auch wenn Sie FastAPI nicht benutzen), schauen Sie sich das kurze Tutorial an: [Einführung in Python-Typen](python-types.md){.internal-link target=_blank}.

Sie schreiben Standard-Python mit Typen:

```Python
from typing import List, Dict
from datetime import date

from pydantic import BaseModel

            op.setRefreshPolicy(Constants.TRUE);
        });

        ComponentUtil.getPathMappingHelper().init();
    }

    /**
     * Gets the path mapping list by process types.
     *
     * @param processTypeList the process type list
     * @return the path mapping list
     */
    public List<PathMapping> getPathMappingList(final Collection<String> processTypeList) {
