【问题描述】：

如何让打字稿不抱怨或如何解决？

[ts] '(dispatch: Dispatch) => void' 类型的参数不可分配给'PostActionTypes' 类型的参数。 类型“（调度：调度）=> void”缺少类型“GetDetailsFailAction”的以下属性：类型、有效负载 [2345] (别名) initPosts(): (dispatch: Dispatch) => void 导入初始化帖子

在另一个 thunk 动作中调度 thunk 动作时我需要添加什么类型？

import axios from "axios";
import  initPosts  from "./init";
import  Dispatch  from "redux";
import  AppActions  from "../types/actions";

export const deletePost = (id: string) => 
  return (dispatch: Dispatch<AppActions>) => 
    axios
      .delete(`https://#####/posts/$id`)
      .then(response => 
        if (response.status === 200) 
          dispatch(initPosts()); // error here
        
      )
      .catch(error => 
        console.log(error);
      );
  ;
;

initPosts 操作

import axios from "axios";
import  AppActions  from "../types/actions";
import  IPost  from "../types/postInterface";
import  Dispatch  from "redux";

export const initPostsStart = (): AppActions => 
  return 
    type: "INIT_POSTS_START"
  ;
;

export const initPostsSuccess = (allPosts: IPost[]): AppActions => 
  return 
    type: "INIT_POSTS_SUCCESS",
    payload: allPosts
  ;
;

export const initPostsFail = (error: string): AppActions => 
  return 
    type: "INIT_POSTS_FAIL",
    payload: error
  ;
;

export const initPosts = () => 
  return (dispatch: Dispatch<AppActions>) => 
    dispatch(initPostsStart());
    axios
      .get("https://#####/posts")
      .then(response => 
        dispatch(initPostsSuccess(response.data));
      )
      .catch(error => 
        dispatch(initPostsFail(error.message));
      );
  ;
;

【参考方案1】：

据记录 here，

你应该输入它，

import  ThunkAction as ReduxThunkAction  from 'redux-thunk';

type ThunkAction = ReduxThunkAction<void, IState, unknown, Action<string>>;
export const initPosts = (): ThunkAction => 
  return (dispatch) => 
    dispatch(initPostsStart());
    axios
      .get("https://#####/posts")
      .then(response => 
        dispatch(initPostsSuccess(response.data));
      )
      .catch(error => 
        dispatch(initPostsFail(error.message));
      );
  ;
;
