reactjs - 如何解决 typescript Redux 连接错误 ActionCreatorsMapObject

Question

typescript 有错误

ERROR in [at-loader] ./src/app/components/profile/userProfile/_userMain.tsx:130:37 
    TS2345: Argument of type 'typeof "/usr/src/app/src/js/src/app/redux/actions/sessionActions"' is not assignable to parameter of type 'ActionCreatorsMapObject'.

ERROR in [at-loader] ./src/app/components/profile/userProfile/_userMain.tsx:133:124 
    TS2345: Argument of type 'typeof UserProfileMain' is not assignable to parameter of type 'ComponentClass<(state: any) => any> | StatelessComponent<(state: any) => any>'.
  Type 'typeof UserProfileMain' is not assignable to type 'StatelessComponent<(state: any) => any>'.
    Type 'typeof UserProfileMain' provides no match for the signature '(props: ((state: any) => any) & { children?: ReactNode; }, context?: any): ReactElement<any>'

是否可以在没有装饰器的情况下解决这个问题？ (@连接)

interface IActions {
    avatarUpload: (file:any) => void;
}

export interface IMainProps {
    auth: number,
    actions: IActions
}

class UserProfileMain extends React.Component<IMainProps, any> {
    constructor(props:any){
        super(props);
        this.state ={
            files: [],
        }
    }

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

const mapStateToProps = (state:any):any => {
    return {
        auth: state.authStatus.data.user.id,
    };
};

const mapDispatchToProps = (dispatch:any):any => {
    return {
        actions: bindActionCreators(sessionActions, dispatch) //First error (130:37)
    };
}
export default connect<typeof mapStateToProps, typeof mapDispatchToProps, IMainProps>(mapStateToProps, mapDispatchToProps)(UserProfileMain); //second error (133:124)

已经尝试过使用UserProfileMain as any 但是遇到了其他一堆错误

也许你知道一些最佳实践

希望大家多多支持

Answer 1

你需要改变你的

actions: bindActionCreators(sessionActions, dispatch)

线到

actions: bindActionCreators<any>(sessionActions, dispatch)

或更具体的内容，因为 redux typescript 定义正在使用 generics .

See the redux typescript definitions here .

<>中的泛型应该是sessionActions的同类型，也是bindActionCreators()函数调用的返回值。
