javascript - 在后退按钮上反应路由器重复路由

问题描述

我有一个反应应用程序。它工作正常。它使用redux，react-router 3。路由工作正常，但是当我按下后退按钮时，它们的路由被重复了。例如localhost:3000/admin/main，我现在从哪里返回，当我返回时，它转到localhost:3000/admin/admin/main，返回未找到。

这是我的路线代码：

export default (
    <Route path="/" component={App}>
    <Route path="home" component={requireNoAuthentication(HomeContainer)} />
        <Route path="login" component={requireNoAuthentication(LoginView)} />
        <Route exact path="admin/user" component={requireAuthentication(UserView)} />
        <Route exact path="admin/main" component={requireAuthentication(UsersListView)} />
        <Route path="secure" component={requireAuthentication(CustomerView)} />
        <Route exact path="*" component={DetermineAuth(NotFound)} />
    </Route>
);

我还收到控制台错误：Adjacent JSX elements must be wrapped in an enclosing tag. 如果有人可以提供帮助将非常感谢！

解决方案

您的HOC包装器（requireNoAuthentication和requireAuthentication）和使用exact（我认为这可能是 react-router v4 唯一的功能？）可能会弄乱您的路由历史记录。尝试重组您的路线，使所有路线都属于App- 一些路线属于RequireAuth，而其余路线是公开的。

附带说明：您可以避免使用React.cloneElementwith 传递的类methods，而是state使用Redux。

路线/index.js

import React from "react";
import { browserHistory, IndexRoute, Router, Route } from "react-router";
import App from "../components/App";
import Home from "../components/Home";
import Info from "../components/Info";
import ShowPlayerRoster from "../components/ShowPlayerRoster";
import ShowPlayerStats from "../components/ShowPlayerStats";
import Schedule from "../components/Schedule";
import Sponsors from "../components/Sponsors";
import RequireAuth from "../components/RequireAuth";

export default () => (
  <Router history={browserHistory}>
    <Route path="/" component={App}>
      <Route component={RequireAuth}>
        <IndexRoute component={Home} />
        <Route path="roster" component={ShowPlayerRoster} />
        <Route path="roster/:id" component={ShowPlayerStats} />
        <Route path="schedule" component={Schedule} />
      </Route>
      <Route path="info" component={Info} />
      <Route path="sponsors" component={Sponsors} />
    </Route>
  </Router>
);

index.js

import React from "react";
import { render } from "react-dom";
import App from "../routes";
import "uikit/dist/css/uikit.min.css";

render(<App />, document.getElementById("root"));

组件/App.js

import React, { Component, Fragment } from "react";
import { browserHistory } from "react-router";
import Header from "./Header";

export default class App extends Component {
  state = {
    isAuthenticated: false
  };

  isAuthed = () => this.setState({ isAuthenticated: true });

  unAuth = () =>
    this.setState({ isAuthenticated: false }, () => browserHistory.push("/"));

  render = () => (
    <Fragment>
      <Header
        isAuthenticated={this.state.isAuthenticated}
        unAuth={this.unAuth}
      />
      {React.cloneElement(this.props.children, {
        isAuthenticated: this.state.isAuthenticated,
        isAuthed: this.isAuthed
      })}
    </Fragment>
  );
}

组件/RequireAuth.js

import React, { Fragment } from "react";
import Login from "./Login";

export default ({ children, isAuthenticated, isAuthed }) =>
  !isAuthenticated ? (
    <Login isAuthed={isAuthed} />
  ) : (
    <Fragment>{children}</Fragment>
  );
