如何创建受保护的路由 react-router-dom
并将响应存储在 localStorage 中,以便用户下次尝试打开时可以再次查看其详细信息。登录后,他们应该重定向到仪表板页面。
所有功能均添加在 ContextApi.代码sandbox 链接中: Code
我尝试过,但没能实现
路线页面
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>
);
}
}
React Router Dom:^ v6
//App.js
<Route path="/"
element={<HomePage /> } />
<Route path="/dashboard"
element={<AuthMiddleware> <DashboardPage /> </AuthMiddleware>}
/>
// AuthMiddelware.js
import { Navigate } from "react-router-dom"
export const AuthMiddleware = (props) => {
const token = true; // get login status here
const { auth=token, children, redirect = '/login' } = props;
if (!auth) {
return <Navigate to={redirect} replace />;
}
return children;
};
