Redux打字稿静态键入Dispatch

Question

我最近为我的react项目切换到Typescript，并且得到了带有redux（thunk）工作的Typescript。我仍然想知道是否可以将接口“绑定”到调度动作，以便检查其形状。

我的actionCreator的代码：

import { Message, SEND_MESSAGE, DELETE_MESSAGE, GET_MESSAGES_SUCCESS, GET_MESSAGES_FAILED, GET_MESSAGES, ChatActionTypes, ChatState } from './types';
import { ActionCreator, Dispatch } from 'redux';
import { ThunkAction } from 'redux-thunk';
import axios from "axios";


export const  getMessages: ActionCreator<ThunkAction<Promise<any>,  ChatState, null, ChatActionTypes>> = () => {
    console.log('i get called')
    return async (dispatch: Dispatch) => {
        try {
            const response = await axios.get('https://jsonplaceholder.typicode.com/todosdffd');
            console.log(response)
            dispatch({
                type: GET_MESSAGES_SUCCESS,
                payload: {
                    loading: false,
                    data: response.data,
                }
            })
        } catch (error) {
            console.log('error triggered')
            dispatch({
                type: typeof GET_MESSAGES_FAILED,
                payload: {
                    loading: false,
                    error: {error }
                }
            })

        }
    }
}


export function sendMessage(newMessage: Message): ChatActionTypes {
    return {
        type: SEND_MESSAGE,
        payload: newMessage
    }
}

export function deleteMessage(timestamp: number): ChatActionTypes {
    return {
        type: DELETE_MESSAGE,
        meta: {
            timestamp
        }
    }
}

我的类型文件

export const SEND_MESSAGE = 'SEND_MESSAGE';
export const DELETE_MESSAGE = 'DELETE_MESSSAGE' ;
export const GET_MESSAGES = 'GET_MESSSAGES' ;
export const GET_MESSAGES_SUCCESS = 'GET_MESSAGES_SUCCESS' ;
export const GET_MESSAGES_FAILED = 'GET_MESSAGES_FAILED' ;

export interface Message {
    user: string,
    message: string,
    timeStamp: number
}

export interface ChatState {
    messages: Message[]
}

interface SendMessageAction {
    type: typeof SEND_MESSAGE,
    payload: Message
}

interface DeleteMessageAction {
    type: typeof DELETE_MESSAGE,
    meta: {
        timestamp: number
    }
}

interface GetMessagesAction {
    type: typeof GET_MESSAGES,
    payload: {
        loading: boolean
    }
}

interface GetMessagesFailedAction {
    type: typeof GET_MESSAGES_FAILED,
    payload: {
        loading: boolean,
        error: object
    }
}

interface GetMessagesSuccessAction {
    type: typeof GET_MESSAGES_SUCCESS,
    payload: {
        loading: boolean,
        data: any[]
    }
}

export type ChatActionTypes = SendMessageAction | DeleteMessageAction | GetMessagesAction | GetMessagesFailedAction | GetMessagesSuccessAction;

我想做的事情：

dispatch<ChatActionTypes>({ ... })

但这不起作用。将接口直接放入actionCreator的代码并将其设置为调度的类型也没有用。

任何建议将不胜感激！
