如何将容器组件传递到 react-router-dom Route? [英] How to pass container components into react-router-dom Route?

问题描述

我目前在 react router redux 中传递正确类型时遇到打字稿问题.

I'm currently having typescript issue with passing the correct type in react router redux.

打字稿错误:

severity: 'Error'
message: 'Type '{ path: "/foo/:id"; component: typeof "<path>..' is not assignable to type 'IntrinsicAttributes & IntrinsicClassAttributes<Route> & Readonly<{ children?: ReactNode; }> & Rea...'.
      Type '{ path: "/foo/:id"; component: typeof "<path>..'  is not assignable to type 'Readonly<RouteProps>'.
        Types of property 'component' are incompatible.
          Type 'typeof "<path>..'  is not assignable to type 'StatelessComponent<RouteComponentProps<any>> | ComponentClass<RouteComponentProps<any>>'.
            Type 'typeof "<path>..'  is not assignable to type 'ComponentClass<RouteComponentProps<any>>'.
              Type 'typeof "<path>..'  provides no match for the signature 'new (props?: RouteComponentProps<any>, context?: any): Component<RouteComponentProps<any>, ComponentState>'.'

这似乎是因为我将容器组件传递到 <Route.../>.但是，我不清楚为什么这不起作用，因为 mapsToProps 应该返回一个 RouteComponentProps.

This seems to be happening because I'm passing a container component into the <Route... />. However, it's not clear to me why this wouldn't work because mapsToProps should be returning a RouteComponentProps.

Foo.ts(组件):

Foo.ts (Component):

export interface Props extends RouteComponentProps<any> {
    a: string;
}

export class Foo extends React.Component<Props, void> {
    public render() {
        //code
    }
}

FooContainer.ts:

FooContainer.ts:

function mapStateToProps(state: State, ownProps: Props): Props {
    const mappedProps: Props = {
        foo: "super"
    };

    return mappedProps;
}

export default connect(mapStateToProps)(Foo);

路线:

import * as React from "react";
import { Route, Switch } from "react-router-dom";
import FooContainer from "./FooContainer";
export const routes = (
    <Switch>
        <Route path="/foo/:id" component={FooContainer} />
    </Switch>
);

nom 库/版本:

 "@types/react": "^16.0.5",
 "@types/react-dom": "^15.5.4",
 "@types/react-redux": "4.4.40",
 "@types/react-router-dom": "4.0.7",
 "@types/react-router-redux": "5.0.8",
 "react": "^15.6.1",
 "react-dom": "^15.6.1",
 "react-redux": "5.0.4",
 "react-router-dom": "4.2.2",
 "react-router-redux": "5.0.0-alpha.6",

如果你看看我的 Props，它扩展了 RouteComponentProps，它是:

If you look at my Props, it extends RouteComponentProps which is:

export interface RouteComponentProps<P> {
  match: match<P>;
  location: H.Location;
  history: H.History;
}

如果这是真的，mapStateToProps 不应该包含匹配项吗?

If that is true, shouldn't mapStateToProps contain the match?

推荐答案

所以我解决了这个问题:

So I got around the problem with :

export default connect(mapStateToProps)(foo) as React.ComponentClass<any>;

不知道为什么我需要用 React.ComponentClass 指定返回类型.不是隐含的吗?

Not sure why I need to specify the return type with React.ComponentClass. Isn't it implicit?
