我正在开发一个小项目,并尝试使用带有Loopback的ReactJS为前端设置用户身份验证。我有用户的登录视图,并且能够注册然后登录,但我试图将其设置到哪里,如果用户未登录,则他们无法查看我在应用程序中的其他页面。我尝试过搜索,并找到了关于如何完成此步骤的非常简洁的文档。我是否需要在路由器中使用Auth,如果他们已登录,我将如何将用户重定向到页面。
import React from 'react';
import { Switch, Route } from 'react-router-dom';
import Carlist from './Carlist';
import About from './About';
import Contact from './contact';
import CarlistDetails from './CarlistDetails';
import Addnew from './Addnew';
import EditCar from './EditCar';
import Thanks from './Thanks';
import Login from "./Login";
import AddUsers from "./AddUsers";
const Main = () => (
<main>
<Switch>
<Route exact path='/' component={Login} />
<Route exact path='/home' component={Carlist} />
<Route exact path='/about' component={About} />
<Route exact path='/Thanks' component={Thanks} />
<Route exact path='/contact' component={Contact} />
<Route exact path='/AddUsers' component={AddUsers} />
<Route exact path='/carlist/add' component={Addnew} />
<Route exact path='/carlist/edit/:id' component={EditCar} />
<Route exact path='/carlist/:id' component={CarlistDetails} />
</Switch>
</main>
)

import React, { Component } from 'react';
import axios from 'axios';
import { Link } from 'react-router-dom';
class Login extends Component {
submitUser(loginUser) {
axios.request({
method: 'post',
url: 'http://localhost:3000/api/Users/login',
data: loginUser
}).then(response => {
this.props.history.push('/home');
}).catch(err => console.log(err));
}
onSubmit(e) {
const loginUser = {
email: this.refs.email.value,
password: this.refs.password.value,
}
this.submitUser(loginUser);
e.preventDefault();
}
render() {
return (
<div>
<h1>Login</h1>
<form onSubmit={this.onSubmit.bind(this)}>
<div className="input-field">
<input type="text" name="email" ref="email" />
<label htmlFor="email">Email</label>
</div>
<div className="input-field">
<input type="text" name="password" ref="password" />
<label htmlFor="password"> Password</label>
</div>
<input type="submit" value="Login" className="btn blue darken-3" />
<Link className="btn right" to="/AddUsers">Create Account</Link>
</form>
</div>
)
}
}
export default Login;

您需要一个包含登录参数的州。
state = {login: false}
然后只渲染其他路由,登录为真。
<Switch>
<Route exact path='/' component={Login} />
{this.state.login && ...}
</Switch>
