`Cookie` is a "sister" class of `Path` and `Query`. It also inherits from the same common `Param` class.

But remember that when you import `Query`, `Path`, `Cookie` and others from `fastapi`, those are actually functions that return special classes.

///

/// info

To declare cookies, you need to use `Cookie`, because otherwise the parameters would be interpreted as query parameters.

        if (groupPager.id != null) {
            cb.query().docMeta().setId_Equal(groupPager.id);
        }
        // TODO Long, Integer, String supported only.

        // setup condition
        cb.query().addOrderBy_Name_Asc();

        // search

    }

    public List<Group> getAvailableGroupList() {
        return groupBhv.selectList(cb -> {
            cb.query().matchAll();

        if (rolePager.id != null) {
            cb.query().docMeta().setId_Equal(rolePager.id);
        }
        // TODO Long, Integer, String supported only.

        // setup condition
        cb.query().addOrderBy_Name_Asc();

        // search

    }

    public List<Role> getAvailableRoleList() {
        return roleBhv.selectList(cb -> {

    response = client.get("/items/", params={"item-query": "nonregexquery"})
    assert response.status_code == 422
    assert response.json() == IsDict(
        {
            "detail": [
                {
                    "type": "string_pattern_mismatch",
                    "loc": ["query", "item-query"],
                    "msg": "String should match pattern '^fixedquery$'",

    response = client.get("/items/", params={"item-query": "nonregexquery"})
    assert response.status_code == 422
    assert response.json() == IsDict(
        {
            "detail": [
                {
                    "type": "string_pattern_mismatch",

                    "msg": "String should match pattern '^fixedquery$'",

Então, você pode declarar sua função assim:

`Cookie` ist eine Schwesterklasse von `Path` und `Query`. Sie erbt von derselben gemeinsamen `Param`-Elternklasse.

Aber erinnern Sie sich, dass, wenn Sie `Query`, `Path`, `Cookie` und andere von `fastapi` importieren, diese tatsächlich Funktionen sind, welche spezielle Klassen zurückgeben.

///

/// info

Um Cookies zu deklarieren, müssen Sie `Cookie` verwenden, da diese Parameter sonst als Query-Parameter interpretiert werden würden.
