今天就跟大家聊聊有关怎么在react中使用router4+redux实现路由权限控制，可能很多人都不太了解，为了让大家更加了解，小编给大家总结了以下内容，希望大家根据这篇文章可以有所收获。
路由权限控制类
在这个方法里面，通过sessionStorage判断是否登录了，如果没有登录，就保存一下当前想要跳转的路由到redux里面。然后跳转到我们登录页。

数据库

企业服务
import React from 'react'
import { Route, Redirect } from 'react-router-dom'
import { setLoginRedirectUrl } from '../actions/loginAction'
class AuthorizedRoute extends React.Component {
render() {
const { component: Component, ...rest } = this.props
const isLogged = sessionStorage.getItem("userName") != null ? true : false;
if(!isLogged) {
setLoginRedirectUrl(this.props.location.pathname);
}
return (
<Route {...rest} render={props => {
return isLogged
? <Component {...props} />
: <Redirect to="/login" />
}} />
)
}
}
export default AuthorizedRoute路由定义信息
路由信息也很简单。只是对需要登录后才能查看的路由用AuthorizedRoute定义。
import React from 'react'
import { BrowserRouter, Switch, Route, Redirect } from 'react-router-dom'
import Layout from '../pages/layout/Layout'
import Login from '../pages/login/Login'
import AuthorizedRoute from './AuthorizedRoute'
import NoFound from '../pages/noFound/NoFound'
import Home from '../pages/home/Home'
import Order from '../pages/Order/Order'
import WorkOrder from '../pages/Order/WorkOrder'
export const Router = () => (
<BrowserRouter>
<div>
<Switch>
<Route path="/login" component={Login} />
<Redirect from="/" exact to="/login"/>{/*注意redirect转向的地址要先定义好路由*/}
<AuthorizedRoute path="/layout" component={Layout} />
<Route component={NoFound}/>
</Switch>
</div>
</BrowserRouter>
)登录页
就是把存在redux里面的地址给取出来，登录成功后就跳转过去，如果没有就跳转到默认页面，我这里是默认跳到主页。因为用了antd的表单，代码有点长，只需要看连接redux那两句和handleSubmit里面的内容。
import React from 'react'
import './Login.css'
import { login } from '../../mock/mock'
import { Form, Icon, Input, Button, Checkbox } from 'antd';
import { withRouter } from 'react-router-dom';
import { connect } from 'react-redux'
const FormItem = Form.Item;
class NormalLoginForm extends React.Component {
constructor(props) {
super(props);
this.isLogging = false;
}
handleSubmit = (e) => {
e.preventDefault();
this.props.form.validateFields((err, values) => {
if (!err) {
this.isLogging = true;
login(values).then(() => {
this.isLogging = false;
let toPath = this.props.toPath === '' ? '/layout/home' : this.props.toPath
this.props.history.push(toPath);
})
}
});
}
render() {
const { getFieldDecorator } = this.props.form;
return (
<Form onSubmit={this.handleSubmit.bind(this)} className="login-form">
<FormItem>
{getFieldDecorator('userName', {
rules: [{ required: true, message: 'Please input your username!' }],
})(
<Input prefix={<Icon type="user" style={{ color: 'rgba(0,0,0,.25)' }} />} placeholder="Username" />
)}
</FormItem>
<FormItem>
{getFieldDecorator('password', {
rules: [{ required: true, message: 'Please input your Password!' }],
})(
<Input prefix={<Icon type="lock" style={{ color: 'rgba(0,0,0,.25)' }} />} type="password" placeholder="Password" />
)}
</FormItem>
<FormItem>
{getFieldDecorator('remember', {
valuePropName: 'checked',
initialValue: true,
})(
<Checkbox>Remember me</Checkbox>
)}
<a className="login-form-forgot" href="">Forgot password</a>
<Button type="primary" htmlType="submit" className="login-form-button"
loading={this.isLogging ? true : false}>
{this.isLogging ? 'Loging' : 'Login'}
</Button>
Or <a href="">register now!</a>
</FormItem>
</Form>
);
}
}
const WrappedNormalLoginForm = Form.create()(NormalLoginForm);
const loginState = ({ loginState }) => ({
toPath: loginState.toPath
})
export default withRouter(connect(
loginState
)(WrappedNormalLoginForm))顺便说一下这里redux的使用吧。我暂时只会基本使用方法：定义reducer，定义actions,创建store，然后在需要使用redux的变量时候去connect一下redux，需要dispatch改变变量时，就直接把actions里面的方法引入，直接调用就可以啦。为了让actions和reducer里面的事件名称对的上，怕打错字和便于后面修改吧，我建了个actionsEvent.js来存放事件名称。
reducer:
import * as ActionEvent from '../constants/actionsEvent'
const initialState = {
toPath: ''
}
const loginRedirectPath = (state = initialState, action) => {
if(action.type === ActionEvent.Login_Redirect_Event) {
return Object.assign({}, state, {
toPath: action.toPath
})
}
return state;
}
export default loginRedirectPathactions:
import store from '../store'
import * as ActionEvent from '../constants/actionsEvent'
export const setLoginRedirectUrl = (toPath) => {
return store.dispatch({
type: ActionEvent.Login_Redirect_Event,
toPath: toPath
})
}创建store
import { createStore, combineReducers } from 'redux'
import loginReducer from './reducer/loginReducer'
const reducers = combineReducers({
loginState: loginReducer //这里的属性名loginState对应于connect取出来的属性名
})
const store = createStore(reducers)
export default store看完上述内容，你们对怎么在react中使用router4+redux实现路由权限控制有进一步的了解吗？如果还想了解更多知识或者相关内容，请关注亿速云行业资讯频道，感谢大家的支持。
