此表达式不可调用。类型'Thunk<Collections，undefined，any，{}，any>‘没有调用签名

Question

这是我的代码。我想调用action，但上面的错误一直在发生。

const action = useStoreActions( (actions : StoreModel) => actions.collections.fetchCollections);

useEffect( () => {
    action()
},[])

这是我的集合对象，我想访问fetchCollections。这是任何简单的react状态管理代码。附言:这里我删除了fetchCollectionsRequest，fetchCollectionsSuccess，fetchCollectionsFailure。

import { Action, action, thunk, Thunk } from 'easy-peasy';

export interface Collections {
    isLoading : boolean;
    collections : any[];
    error : string;
    fetchCollections : Thunk<Collections>;
}

export const collectionsModel : Collections = {
    isLoading : false,
    collections : [],
    error : '',
   
    fetchCollections : thunk( actions => {
        actions.fetchCollectionsRequest();
        axios.get('/categories?filter={"where":{"isHidden":false}}')
            .then( res => actions.fetchCollectionsSuccess(res.data))
            .catch( err => actions.fetchCollectionsFailure(err.message));
    }),
}

这是我的model.tsx

import { collectionsModel, Collections } from './collectionsModel';

export interface StoreModel {
    collections : Collections;;
}

export const model = {
    collections : collectionsModel,
}

这是因为您正在键入useStoreActions挂钩的actions参数(该参数并不直接符合正确的类型)。

相反，请使用typed hooks

// outside the component
import { createTypedHooks } from 'easy-peasy';

const { useStoreActions } = createTypedHooks<StoreModel>();

// inside the component:
const { fetchCollections } = useStoreActions(actions => actions.collections);
