React-router 2.0:以编程方式更改路由(URL未更新)

Question

我在使用react-router 2.0进行编程路由时遇到了一些麻烦

文档说要使用

this.context.router.push('/test');

这是正确导航,但是我的浏览器上的URL保持不变,即使来自其他页面(/ test)的组件已呈现并且路由更改成功,也不会更新.

如何获取要更新的URL？

Answer 1

this.props.history.push('/some/path'); 已被弃用.

我们现在应该使用以下内容:

import { browserHistory } from 'react-router'

然后,无论您想要导航到哪里 - 代码中的某个位置 - 都可以:

browserHistory.push('/some/path');

这就是我配置routes.jsx处理路由机制的文件的方法:

//Require react.
import React from "react";
//Require routing variables.
import { Router, Route, IndexRoute, browserHistory } from "react-router";
//Example components.
import MainComponent from "../containers/main.js";
import HomeComponent from "../containers/home.js";

var Routes = (
    <Router history={browserHistory}>
        <Route path="/" component={MainComponent}>
            <IndexRoute component={HomeComponent} />
            <Route path="/example" component={ExampleComponent} />
        </Route>
    </Router>
);

module.exports = Routes;

我正在使用webpack.在webpack中,我也有:

... bla ... bla... bla ...
module: {

},
devServer: {
    historyApiFallback: true
},
plugins: [

]
... bla ... bla... bla ...

[免责声明:我现在使用的是TypeScript而不是ES6]

这就是我现在用react ^15.6.1&做的事情.react-dom ^15.6.1

index.tsx

import * as React from "react";
import * as ReactDOM from "react-dom";
import Routes from "./configuration/routes";
ReactDOM.render(
  Routes,
  document.getElementById("app")
);

routes.tsx

import * as React from "react";
import { BrowserRouter, HashRouter  } from 'react-router-dom';
import App from "../containers/App";

let Routes: any = (
    // <BrowserRouter>
    //     <App someDefaultValue/>
    // </BrowserRouter>

    // HashRouter adds the # in front of our paths :) - check the browser's URL to see.
    <HashRouter>
        <App someDefaultValue/>
    </HashRouter>
);
export default Routes;

App.tsx

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

import Header from "../components/header-component/header";
import Main from "../components/main-component/main";
import Footer from "../components/footer-component/footer";

interface IComponentProps { someDefaultValue: boolean; }
interface IComponentState { loading: boolean; }

class App extends React.Component<IComponentProps, IComponentState> {
    constructor() {
        super();

        this.state = {
            loading: true
        };
    }

    render() {
        const { loading } = this.state;
        if(loading) {
            //Render something or something else..
        }

        return (
            <div className="app-container">
                <Switch>
                    <Route path='/' component={Header}/>
                </Switch>
                <Switch>
                    <Route path='/' component={Main}/>
                </Switch>
                <Switch>
                    <Route path='/' component={Footer}/>
                </Switch>
            </div>
        );
    }
}
export default App;

然后你可以使用这样的东西在点击(或任何......)时在菜单项上放置导航 menu.tsx

import * as React from "react";
import { Link } from 'react-router-dom'

class Menu extends React.Component {
    render() {
        return (
            <div>
                <Link to='/home'>
                    <div>Home</div>
                </Link>
                <Link to='/about'>
                    <div>About</div>
                </Link>
            </div>);
    }
}
export default Menu;

要"以编程方式"导航:

this.props.history.push('/wherever');

我使用的原因HashRouter是因为我注意到BrowserRouter当人们保存"书签"等时它会中断.HashRouter允许我的用户无缝导航我的网站:)

如果我需要展示如何BrowserRouter运作,我可以 - 只是问 - 它几乎相同 - 但你会发现它只在你在网站内导航时表现.当您从外部导航时,就是错误开始发生的时候.

哦,是的,差点忘了 - 我没有真正测试过这个,但我认为我们仍然需要

devServer: { historyApiFallback: true } 

在我们webpack.config.js？不知道:))但是我现在在那里......

这个答案可能就是您正在寻找的内容，它说要使用

this.props.history.push('/some/path');

当在组件内部时
