如何使用react-router-dom创建一个受保护的路由，并将响应存储在localStorage中，以便用户下次打开时可以再次查看他们的详细信息。登录后，他们应该重定向到仪表盘页面。

所有功能都添加在ContextApi中。 Codesandbox链接：Code

我尝试过，但无法实现

路由页面

import React, { useContext } from "react";
import { globalC } from "./context";
import { Route, Switch, BrowserRouter } from "react-router-dom";
import About from "./About";
import Dashboard from "./Dashboard";
import Login from "./Login";
import PageNotFound from "./PageNotFound";

function Routes() {
  const { authLogin } = useContext(globalC);
  console.log("authLogin", authLogin);

  return (
    <BrowserRouter>
      <Switch>
        {authLogin ? (
          <>
            <Route path="/dashboard" component={Dashboard} exact />
            <Route exact path="/About" component={About} />
          </>
        ) : (
          <Route path="/" component={Login} exact />
        )}

        <Route component={PageNotFound} />
      </Switch>
    </BrowserRouter>
  );
}
export default Routes;

上下文页面

import React, { Component, createContext } from "react";
import axios from "axios";

export const globalC = createContext();

export class Gprov extends Component {
  state = {
    authLogin: null,
    authLoginerror: null
  };
  componentDidMount() {
    var localData = JSON.parse(localStorage.getItem("loginDetail"));
    if (localData) {
      this.setState({
        authLogin: localData
      });
    }
  }

  loginData = async () => {
    let payload = {
      token: "ctz43XoULrgv_0p1pvq7tA",
      data: {
        name: "nameFirst",
        email: "internetEmail",
        phone: "phoneHome",
        _repeat: 300
      }
    };
    await axios
      .post(`https://app.fakejson.com/q`, payload)
      .then((res) => {
        if (res.status === 200) {
          this.setState({
            authLogin: res.data
          });
          localStorage.setItem("loginDetail", JSON.stringify(res.data));
        }
      })
      .catch((err) =>
        this.setState({
          authLoginerror: err
        })
      );
  };
  render() {
    // console.log(localStorage.getItem("loginDetail"));
    return (
      <globalC.Provider
        value={{
          ...this.state,
          loginData: this.loginData
        }}
      >
        {this.props.children}
      </globalC.Provider>
    );
  }
}
