打字稿反應-redux

Question

我想使用做出反應，終極版與打字稿到dipatch的動作，但是當我使用mapDisPatchToProps()，我不知道如何定義的dispatch類型，有我的代碼：

這是組件文件：

import * as React from 'react'; 

    import Content from '../component/content'; 

    interface Props { 
     allCityInformation: {'cityName': string, 'img': string}[]; 
     onGetAllCityInformation: Function; 
    } 

    class HomePage extends React.Component<Props> { 

     componentDidMount() { 
     this.props.onGetAllCityInformation(); 
     } 

     render() { 
     return (
      <div> 
      <Content/> 
      </div> 
     ); 
     } 
    } 

export default HomePage; 

這是我的容器文件：

import { connect } from 'react-redux'; 
import HomePage from '../pages/homePage'; 

export type DispatchGetCityInformation =() => void; 

const mapDispatchToProps = (dispatch: DispatchGetCityInformation) => { 
    return{ 
    onGetAllCityInformation: dispatch(getCityInformation()) 
    }; 
}; 
export default connect(() => {return {}; 
}, mapDispatchToProps)(HomePage); 

現在，該錯誤信息是： enter image description here

那麼，如何解決這個問題呢？

Answer 1

這樣

import { Dispatch } from 'redux'; 
/*other code*/ 
const mapDispatchToProps = (dispatch: Dispatch<object>) => ({ 
    asyncRequest: (name: string) => dispatch(someAction(name)), 
    otherAction:() => dispatch(someAction()) 
});
