我有以下一段代码,它接收一个历史对象作为props:
const ChildComponent = ({ history }) => (
<div className={styles.body}>
<div className={styles.cta}>
<FloatingActionButton onClick={() => history.push(routes[4].path)}>
<span>Click me</span>
</FloatingActionButton>
</div>
</div>
);
我如何为这个历史props添加类型检查,这是通过用 withRouter HOC 包装它的父级来接收的?我能想到的一种方法是写这样的东西:
interface Props {
history: {
push(url: string): void;
};
}
但我确信这不是正确的方法,因为历史对象的其余属性正在丢失。
你能建议这样做的正确方法吗?
根据@Oblosys 的回答更新了代码
import { withRouter, RouteComponentProps } from "react-router-dom";
interface Props extends RouteComponentProps<any> {
/* Parent component's props*/
}
class Parent extends React.Component<Props, {}> {
render() {
return <ChildComponent history={this.props.history} />;
}
}
//Child component related stuff
interface ChildComponentProps extends RouteComponentProps<any> {}
const ChildComponent: React.SFC<ChildComponentProps> = (props) => (
<div className={styles.body}>
<div className={styles.cta}>
<FloatingActionButton onClick={() => history.push(routes[4].path)}>
<span>Click me</span>
</FloatingActionButton>
</div>
</div>
);
function mapStateToProps(state: types.AppState) {
/* related code */
}
function mapDispatchToProps(dispatch: Redux.Dispatch<types.AppState>{
/* related code */
}
export default withRouter(connect(mapStateToProps, mapDispatchToProps)(Parent));
但是,现在我收到以下错误:
Type '{ history: History; }' is not assignable to type 'ChildComponentProps'.
Property 'match' is missing in type '{ history: History; }'
