javascript - 如何使用react-router处理身份验证？

Question

尝试使某些路由需要身份验证。

我有这个:

class App extends Component {
  render() {
    const menuClass = `${this.props.contentMenuClass} col-xs-12 col-md-9`;
    return (  
      <BrowserRouter history={browserHistory}>
        <div className="App">
          <Header properties={this.props} />
            <div className="container-fluid">
              <div className="row">
                <SideNav />
                <div className={menuClass} id="mainContent">
                  <Switch>
                    {routes.map(prop =>
                        (
                          <Route
                            path={prop.path}
                            component={prop.component}
                            key={prop.id}
                            render={() => (
                              !AuthenticationService.IsAutheenticated() ? 
                                <Redirect to="/Login"/>
                               : 
                               <Route path={prop.path}
                               component={prop.component}
                               key={prop.id}/>

                            )}
                          />
                        ))}
                  </Switch>
                </div>
              </div>
            </div>
          {/* <Footer /> */}

        </div>

      </BrowserRouter>
    );
  }
}

const mapStateToProps = state => ({
  contentMenuClass: state.menu,
});

export default connect(mapStateToProps)(App);

注意:是的，身份验证服务可以正常工作。

对于每条路线，我都会检查用户是否经过身份验证，如果没有，那么我想将他们重定向到登录页面，如果是，那么它将以“/”路线登陆第一页。

我得到的是:

react-dom.development.js:14227 The above error occurred in the <Route> component:
    in Route (created by App)
    in Switch (created by App)
    in div (created by App)
    in div (created by App)
    in div (created by App)
    in div (created by App)
    in Router (created by BrowserRouter)
    in BrowserRouter (created by App)
    in App (created by Connect(App))
    in Connect(App)
    in Provider

我哪里做错了？

一个简单的解决方案是制作 HOC (高阶组件)包装所有 protected 路由。

根据您的应用程序的嵌套程度，您可能需要使用本地状态或 redux状态。

工作示例:https://codesandbox.io/s/5m2690nn6n (这使用本地状态)

routes/index.js

import React from "react";
import { BrowserRouter, Switch, Route } from "react-router-dom";
import Home from "../components/Home";
import Players from "../components/Players";
import Schedule from "../components/Schedule";
import RequireAuth from "../components/RequireAuth";

export default () => (
  <BrowserRouter>
    <RequireAuth>
      <Switch>
        <Route exact path="/" component={Home} />
        <Route exact path="/players" component={Players} />
        <Route path="/schedule" component={Schedule} />
      </Switch>
    </RequireAuth>
  </BrowserRouter>
);

组件/RequireAuth.js

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

class RequireAuth extends Component {
  state = { isAuthenticated: false };

  componentDidMount = () => {
    if (!this.state.isAuthenticated) {
      this.props.history.push("/");
    }
  };

  componentDidUpdate = (prevProps, prevState) => {
    if (
      this.props.location.pathname !== prevProps.location.pathname &&
      !this.state.isAuthenticated
    ) {
      this.props.history.push("/");
    }
  };

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

  unAuth = () => this.setState({ isAuthenticated: false });

  render = () =>
    !this.state.isAuthenticated ? (
      <Login isAuthed={this.isAuthed} />
    ) : (
      <Fragment>
        <Header unAuth={this.unAuth} />
        {this.props.children}
      </Fragment>
    );
}

export default withRouter(RequireAuth);

或者，您可以创建一个包含 protected 路由的 protected 组件，而不是包装路由。

工作示例:https://codesandbox.io/s/yqo75n896x (使用 redux 而不是本地状态)。

routes/index.js

import React from "react";
import { BrowserRouter, Route, Switch } from "react-router-dom";
import { createStore } from "redux";
import { Provider } from "react-redux";
import Home from "../components/Home";
import Header from "../containers/Header";
import Info from "../components/Info";
import Sponsors from "../components/Sponsors";
import Signin from "../containers/Signin";
import RequireAuth from "../containers/RequireAuth";
import rootReducer from "../reducers";

const store = createStore(rootReducer);

export default () => (
  <Provider store={store}>
    <BrowserRouter>
      <div>
        <Header />
        <Switch>
          <Route exact path="/" component={Home} />
          <Route path="/info" component={Info} />
          <Route path="/sponsors" component={Sponsors} />
          <Route path="/protected" component={RequireAuth} />
          <Route path="/signin" component={Signin} />
        </Switch>
      </div>
    </BrowserRouter>
  </Provider>
);

容器/RequireAuth.js

import React from "react";
import { Route, Redirect } from "react-router-dom";
import { connect } from "react-redux";
import ShowPlayerRoster from "../components/ShowPlayerRoster";
import ShowPlayerStats from "../components/ShowPlayerStats";
import Schedule from "../components/Schedule";

const RequireAuth = ({ match: { path }, isAuthenticated }) =>
  !isAuthenticated ? (
    <Redirect to="/signin" />
  ) : (
    <div>
      <Route exact path={`${path}/roster`} component={ShowPlayerRoster} />
      <Route path={`${path}/roster/:id`} component={ShowPlayerStats} />
      <Route path={`${path}/schedule`} component={Schedule} />
    </div>
  );

export default connect(state => ({
  isAuthenticated: state.auth.isAuthenticated
}))(RequireAuth);

您甚至可以通过创建包装函数来获得更加模块化的效果。您可以通过简单地包裹组件来选择任何路线。我没有代码框示例，但它类似于 setup .

例如:<Route path="/blog" component={RequireAuth(Blog)} />
