反应路由器前缀

Jir*_*Jir 6 reactjs react-router

我正在 React 中构建一个多语言站点,并且我正在使用 React 路由器进行路由。现在我已经设置了前缀必须存在才能转换到路由。

我想要做的是以下内容:当我转到localhost:3000 时,我希望我的应用程序转换到 home 组件。当我转到 localhost:3000/jp 时,我仍然想转换到 home 组件,除了现在我的语言前缀是jp

我希望英语是默认语言,而对于其他语言,它们必须出现在前缀中。现在,如果我输入localhost:3000/en ,它只会转换到 home 组件。

有没有办法做到这一点?

import React, { Component } from 'react';
import { Route, Switch } from "react-router-dom";

import { Home } from '../containers/home';
import { About } from '../containers/about';
import { Contact } from '../containers/contact';


export default class Routes extends Component {
    render(){
        return(
            <Switch>
                <Route path="/:lang/about" component={About} />
                <Route path="/:lang/contact" component={Contact} />
                <Route path="/:lang/" component={Home} />
            </Switch>
        );
    }
}

只需Redirect在最后添加一个,当没有其他任何事情时,它将被匹配,它将重定向到/en

import React, { Component } from 'react';
import { Route, Switch, Redirect } from "react-router-dom";

import { Home } from '../containers/home';
import { About } from '../containers/about';
import { Contact } from '../containers/contact';


export default class Routes extends Component {
    render(){
        return(
            <Switch>
                <Route path="/:lang/about" component={About} />
                <Route path="/:lang/contact" component={Contact} />
                <Route path="/:lang/" component={Home} />
                <Redirect to="/en" />
            </Switch>
        );
    }
}

更新的答案(由于评论

问题是/:lang/will 匹配/about并且 lang 将设置为about.

一个解决方案是使用render路线的道具并决定你想在那里做什么

export default class Routes extends Component {
  render() {
    const supportedLanguages = ["en", "jp", "de", "es"];
    return (
      <Switch>
        <Route path="/:lang/about" component={About} />
        <Route path="/:lang/contact" component={Contact} />
        <Route
          path="/:lang/"
          render={props =>
            supportedLanguages.includes(props.match.params.lang) ? (
              <Home {...props} />
            ) : (
              <Redirect to={`/en/${props.match.params.lang}`} />
            )
          }
        />
      </Switch>
    );
  }
}
