Question

已连接的React Router导出RouterState的类型，这很棒！但是，我看不到match的输入。假设那些也可以导入并添加到减速器中，例如RouterState在下面以及在减速器中使用：

https://github.com/supasate/connected-react-router/blob/master/examples/typescript/src/reducers/index.ts#L13

const rootReducer = (history: History) => combineReducers({
  count: counterReducer,
  router: connectRouter(history)

})

export interface State {
  count: number
  router: RouterState
}

没有这些，您不能真正在连接的组件中使用this.props.match来匹配参数等。对于使用TypeScript并需要添加到reducer的用户来说，这里是否有解决方法？还是我在这里缺少关键部分？非常感谢！

您有2种方法。

您可以使用createMatchSelector中的mapStateToProps函数从您的状态中提取match。 DEMO

import * as React from "react";
import { connect } from "react-redux";
import { createMatchSelector } from "connected-react-router";
import { match } from "react-router";
import { State } from "./reducers";

interface StateProps {
  match: match<{ name?: string }>;
}

const Hello = (props: StateProps) => (
  <div>Hello {props.match.params.name}!</div>
);

const mapStateToProps = (state: State) => {
  const matchSelector = createMatchSelector("/hello/:name");
  return {
    match: matchSelector(state)
  };
};

export default connect<StateProps>(
  mapStateToProps,
  null
)(Hello);

您可以直接从路由器而不是从州获得match。 DEMO

import * as React from "react";
import { RouteComponentProps, withRouter } from "react-router";

const Hello = (props: RouteComponentProps<{ name?: string }>) => (
  <div>Hello {props.match.params.name}!</div>
);

export default withRouter(Hello);

连接React Router和TypeScript以进行匹配
