我遇到一个问题,我有一个无状态组件,该组件从react-router-dom
传递了History对象,然后通过props将该对象向下传递给有状态对象。 Typescript似乎不认为我可以将历史对象作为道具传递下来。
这是我的组成部分
import { History } from 'history';
import * as React from 'react';
import { RouteComponentProps, withRouter } from 'react-router-dom';
const SignInPage = ({ history }: { history: History }) =>
<div>
<h1>SignIn</h1>
<SignInForm history={history} />
</div>
class SignInForm extends React.Component<RouteComponentProps<{}>, {}> {
constructor(props: RouteComponentProps<{}>) {
super(props);
}
public handleClick = () => {
const { history } = this.props;
history.push('/home')
};
public render() {
return (
<button onClick={this.handleClick}>Sign In!</button>
);
}
}
export default withRouter(SignInPage);
export { SignInForm };
我得到的错误是这个。
Type '{ history: History; }' is not assignable to type 'IntrinsicAttributes & IntrinsicClassAttributes<SignInForm> & Readonly<{ children?: ReactNode; }> ...'.
Type '{ history: History; }' is not assignable to type 'Readonly<RouteComponentProps<{}, StaticContext>>'.
Property 'location' is missing in type '{ history: History; }'.
答案 0 :(得分:2)
我从没使用过React Router,但如果我正确理解了键入,则通过声明SignInForm extends React.Component<RouteComponentProps<{}>, {}>
来表示SignInForm
需要 all 一条路线的道具组件通常在由React Router调用时接收。由于您是自己调用它并仅传递历史记录,因此您只需将其声明为SignInForm extends React.Component<{history: History}, {}>
。
