(alias) deleteCategory(id: number): (dispatch: Dispatch<AnyAction>) => void
import deleteCategory
Argument of type '(dispatch: Dispatch) => void' is not assignable to parameter of type 'AnyAction'.
Property 'type' is missing in type '(dispatch: Dispatch) => void' but required in type 'AnyAction'.ts(2345)
删除类别的实施:
export const deleteCategory = (id: number) => (dispatch: Dispatch) => {
deleteCategoryAPI(id)
.then(() => {
dispatch({
type: DELETE_CATEGORY,
category: id,
});
})
.catch((error) => console.error(error));
};
deleteCategoryAPI的实现:
export async function addCategoryAPI(category: CategoryType) {
return fetch(`${API_URL}/categories`, {
method: "POST",
body: JSON.stringify(category),
headers: { "Content-Type": "application/json; charset=UTF-8" },
}).then((response) => response.json());
}
我在这里使用了有问题的代码:
const categoryList = getCategoryList(categoryState, dispatch);
...
return (
<List
dataSource={categoryList}
renderItem={({ name, onDelete }) => (
<List.Item>
<CategoryItem name={name} onDelete={onDelete} />
</List.Item>
)}
/>
);
有什么问题吗?为此花了几个小时。
有趣的是,当我调用
dispatch(deleteCography(category.\u id))
功能组件中的其他地方时,例如,它可以正常工作。。多谢各位 > P>我可以首先考虑几种不同的方式,你可以考虑这取决于你想投入多少努力,对你想要的香草实现的真实性,以及你想要的准确度。

的情况下,可以创建对configureStore
或createSlice
的引用,并根据选择操作打字。在下面的代码中,我将createSlice函数包装在createSlicePlus
中,在幕后添加了一系列方便的逻辑,并增强了参数和返回类型
// convenience `request` wrapper around store `dispatch` that abstracts the rest
const promise = counter.request.decrementThunk(500)
// even the RTK thunk promise is typed appropriately
promise.abort()
function CategoryItem({ name, onDelete }: categoryItemPropsType) {
export type categoryItemPropsType = {
name: string;
onDelete: () => void;
};
// create your own dispatch function reference with custom typings
export const dispatchStore = store.dispatch as typeof store.dispatch | Dispatch<any>
// use custom typed dispatch (unfortunately, you can pass it almost `any`thing)
dispatchStore(myThunk('id123'))
// optional
export const dispatchStore = store.dispatch
// type each dispatch as any (not good if you need to use 'abort', etc)
dispatchStore(myThunk('id123') as any)
// convenience `request` wrapper around store `dispatch` that abstracts the rest
const promise = counter.request.decrementThunk(500)
// even the RTK thunk promise is typed appropriately
promise.abort()
