Mr_*_*een 6 reactjs react-router
在我的项目中,我必须在不更改 url 的情况下从一个组件导航到另一个组件。为此,我使用了MemoryRouter按预期工作的方法。但是现在相同的想法应该适用于不同的路线,即/one和/two。例如,
/one --> BrowserRouter (url change visible)
/
/first
/second
/third
/two --> BrowserRouter (url change visible)
/
/first
/second
/third

对于新的可见路由,即/one和/two,已经建立的工作内存路由(即/,/first,/second,/third)应该按照/one和 中提供的相应数据正常工作/two。
我正在努力使用以下结构代码将 MemoryRoutes 包含在 BrowserRoutes 中:
<BrowserRouter>
<Switch>
<Route path="/one" render={() => <MemoryComp configFor="Dave"></MemoryComp>}></Route>
<Route path="/two" render={() => <MemoryComp configFor="Mike"></MemoryComp>}></Route>
</Switch>
</BrowserRouter>

然后是MemoryComp持有:
<MemoryRouter history={customHistory}>
<Switch>
<Route path="/" render={(props) => <InitPage configFor={this.props.configFor} history={props.history}></InitPage>}></Route>
<Route path="/first" component={FirstPage}></Route>
<Route path="/second" component={SecondPage}></Route>
<Route path="/third" component={ThirdPage}></Route>
</Switch>
</MemoryRouter>

我正在努力实现的目标:
history以实现相同)注意:这更有可能用服务器路由来处理浏览器路由内容。此外,这似乎可以通过任何 react-stepper 插件来实现。但试图了解我在这里做错了什么,只是为了学习目的。
这是整个最小化的代码,可在Stackblitz上使用(不工作):
import React, { Component } from 'react';
import { render } from 'react-dom';
import './style.css';
import { BrowserRouter, MemoryRouter, Route, Switch } from 'react-router-dom';
import { createBrowserHistory } from "history";
const customHistory = createBrowserHistory();
class MemoryComp extends Component{
render(){
return(
<MemoryRouter history={customHistory}>
<Switch>
<Route path="/" render={(props) => <InitPage configFor={this.props.configFor} history={props.history}></InitPage>}></Route>
<Route path="/first" component={FirstPage}></Route>
<Route path="/second" component={SecondPage}></Route>
<Route path="/third" component={ThirdPage}></Route>
</Switch>
</MemoryRouter>
);

起初我认为与Switch组合有问题MemoryRouter,但经过一些调试后我意识到它实际上是完全独立的。
您遇到的问题是您的基本内存路由需要为exact,否则所有其他路由都将匹配该路由,并且将返回第一个 ('/')。只需添加exact到您的基本路线。
<MemoryRouter>
<Switch>
<Route exact path="/" render={(props) => <InitPage configFor={this.props.configFor} history={props.history}></InitPage>}></Route>
<Route path="/first" component={FirstPage}></Route>
<Route path="/second" component={SecondPage}></Route>
<Route path="/third" component={ThirdPage}></Route>
</Switch>
</MemoryRouter>

如果您有更多的嵌套路由总是添加精确到根,请小心,例如/first需要精确以使其正常工作:
<Route exact path="/first" component={FirstPage}></Route>
<Route path="/first/nested-1" component={SecondPage}></Route>
<Route path="/first/nested-2" component={ThirdPage}></Route>
