Detailed explanation of login verification control steps for React from react-router route

import React from 'react' import {connect} from 'react-redux'; function requireAuthentication(Component) { // 组件有已登陆的模块 直接返回 (防止从新渲染) if (Component.AuthenticatedComponent) { return Component.AuthenticatedComponent } // 创建验证组件 class AuthenticatedComponent extends React.Component { static contextTypes = { router: React.PropTypes.object.isRequired, } state = { login: true, } componentWillMount() { this.checkAuth(); } componentWillReceiveProps(nextProps) { this.checkAuth(); } checkAuth() { // 判断登陆 const token = this.props.token; const login = token ? token.login : null; // 未登陆重定向到登陆页面 if (!login) { let redirect = this.props.location.pathname + this.props.location.search; this.context.router.push('/login?message=401&redirect_uri=' + encodeURIComponent(redirect)); return; } this.setState({login}); } render() { if (this.state.login) { return  } return '' } } // 不使用 react-redux 的话直接返回 // Component.AuthenticatedComponent = AuthenticatedComponent // return Component.AuthenticatedComponent function mapStateToProps(state) { return { token: state.token, }; } function mapDispatchToProps(dispatch) { return {}; } Component.AuthenticatedComponent = connect(mapStateToProps, mapDispatchToProps)(AuthenticatedComponent); return Component.AuthenticatedComponent }
