【共享单车】—— React后台管理系统开发手记：城市管理和订单管理
前言：以下内容基于React全家桶+AntD实战课程的学习实践过程记录。最终成果github地址：https://github.com/66Web/react-antd-manager，欢迎star。
一、城市管理
- pages->city->index.js：对应路由/admin/city
- 顶部子组件一：选择表单
class FilterForm extends React.Component{ render(){ const { getFieldDecorator } = this.props.form; return ( <Form layout="inline"> <FormItem label="城市"> { getFieldDecorator('city_id')( <Select style={{width:100}} placeholder="全部" > <Option value="">全部</Option> <Option value="1">北京市</Option> <Option value="2">天津市</Option> <Option value="3">深圳市</Option> </Select> ) } </FormItem> <FormItem label="用车模式"> { getFieldDecorator('mode')( <Select style={{ width: 120 }} placeholder="全部" > <Option value="">全部</Option> <Option value="1">指定停车点模式</Option> <Option value="2">禁停区模式</Option> </Select> ) } </FormItem> <FormItem label="营运模式"> { getFieldDecorator('op_mode')( <Select style={{ width: 80 }} placeholder="全部" > <Option value="">全部</Option> <Option value="1">自营</Option> <Option value="2">加盟</Option> </Select> ) } </FormItem> <FormItem label="加盟商授权状态"> { getFieldDecorator('auth_status')( <Select style={{ width: 100 }} placeholder="全部" > <Option value="">全部</Option> <Option value="1">已授权</Option> <Option value="2">未授权</Option> </Select> ) } </FormItem> <FormItem> <Button type="primary" style={{margin:'0 20px'}}>查询</Button> <Button>重置</Button> </FormItem> </Form> ); } } FilterForm = Form.create({})(FilterForm); -
弹框子组件二：开通城市表单
class OpenCityForm extends React.Component{ render(){ const formItemLayout = { labelCol:{ //label标签占据列数 span:5 }, wrapperCol:{ //Form表单占据列数 span:19 } } const { getFieldDecorator } =this.props.form; return ( <Form layout="horizontal"> <FormItem label="选择城市" {...formItemLayout}> { getFieldDecorator('city_id',{ initialValue:'1' })( <Select style={{ width: 100 }}> <Option value="">全部</Option> <Option value="1">北京市</Option> <Option value="2">天津市</Option> </Select> ) } </FormItem> <FormItem label="营运模式" {...formItemLayout}> { getFieldDecorator('op_mode', { initialValue: '1' })( <Select style={{ width: 100 }}> <Option value="1">自营</Option> <Option value="2">加盟</Option> </Select> ) } </FormItem> <FormItem label="用车模式" {...formItemLayout}> { getFieldDecorator('use_mode', { initialValue: '1' })( <Select style={{ width: 100 }}> <Option value="1">指定停车点</Option> <Option value="2">禁停区</Option> </Select> ) } </FormItem> </Form> ); } } OpenCityForm = Form.create({})(OpenCityForm); -
Easy Mock城市管理的数据接口：/open_city
{ "code": 0, "msg": "", "list": { "item_list|10": [{ "id|+1": 1, "name": "@city", "mode|1-2": 1, "op_mode|1-2": 1, "franchisee_id": 77, "franchisee_name": "松果自营", "city_admins|1-2": [{ "user_name": "@cname", "user_id|+1": 10001 }], "open_time": "@datetime", "sys_user_name": "@cname", "update_time": 1546580667000 }] }, page: 1, page_size: 10, total: 20 }
- componentDidMount()中：调用this.requestList()，默认请求接口数据
componentDidMount(){ this.requestList(); } // 默认请求我们的接口数据 requestList = ()=>{ let _this = this; axios.ajax({ url: '/open_city', data:{ params:{ page:this.params.page } } }).then((res)=>{ let list = res.list.item_list.map((item, index) => { item.key = index; return item; }); this.setState({ list:list, pagination:Utils.pagination(res,(current)=>{ _this.params.page = current; _this.requestList(); }) }) }) }
-
Easy Mock城市开通的数据接口：/city/open
{ "code": 0, "list": "开通成功" }
-
【开通城市】按钮：监听onClick事件，调用this.handleOpenCity()显示弹框
state = { list:[], isShowOpenCity:false //默认隐藏弹框 } // 开通城市 handleOpenCity = ()=>{ this.setState({ isShowOpenCity:true }) } -
Modal关键属性visible控制弹框的显示隐藏，关键事件onOk调用this.handleSubmit()提交表单信息
<Modal title="开通城市" visible={this.state.isShowOpenCity} onCancel={()=>{ this.setState({ isShowOpenCity:false }) }} onOk={this.handleSubmit} > <OpenCityForm wrappedComponentRef={(inst)=>{this.cityForm = inst;}}/> </Modal>wrappedComponentRef属性：拿到表单中的信息对象inst，通过this.cityForm存到state中
-
城市开通信息提交
// 城市开通提交 handleSubmit = ()=>{ let cityInfo = this.cityForm.props.form.getFieldsValue(); console.log(cityInfo); axios.ajax({ url:'/city/open', data:{ params:cityInfo } }).then((res)=>{ if(res.code === 0){ message.success('开通成功'); this.setState({ isShowOpenCity:false }) this.requestList(); } }) }

Easy Mock结束订单成功数据接口：/order/finish_order
{ "code": 0, "list": "ok" }
-
【结束订单】按钮：监听onClick事件，调用this.handleConfirm()显示确认结束弹框
<Button type="primary" style={{marginLeeft: 10}} onClick={this.handlConfirm}>结束订单</Button>//订单结束确认 handleConfirm = () => { let item = this.state.selectedItem; if(!item){ Modal.info({ title: '信息', content: '请选择一条订单进行结束' }) return; } axios.ajax({ url: '/order/ebike_info', data: { params: { orderId: item.id } } }).then((res) => { if(res.code === 0 ){ this.setState({ orderInfo: res.list, orderConfirmVisible: true }) } }) } -
确认取消：打开Modal弹框，显示要取消的订单信息
<Modal title="结束订单" visible={this.state.orderConfirmVisible} onCancel={() => { this.setState({ orderConfirmVisible: false }) }} onOk={this.handleFinishOrder} width={600}> <Form layout="horizontal"> <FormItem label="车辆编号" {...formItemLayout}> {this.state.orderInfo.bike_sn} </FormItem> <FormItem label="剩余电量" {...formItemLayout}> {this.state.orderInfo.battery + '%'} </FormItem> <FormItem label="行程开始时间" {...formItemLayout}> {this.state.orderInfo.start_time} </FormItem> <FormItem label="当前位置" {...formItemLayout}> {this.state.orderInfo.location} </FormItem> </Form> </Modal> -

实例代码：
import React from 'react' import { Card, Button, Table, Form, Select, Modal, message, DatePicker } from 'antd'; import axios from './../../axios/index'; import Utils from './../../utils/utils'; const FormItem = Form.Item; const Option = Select.Option; export default class Order extends React.Component{ state = { orderInfo: {}, orderConfirmVisible: false } params = { page:1 } componentDidMount(){ this.requestList(); } requestList = () => { let _this = this; axios.ajax({ url: '/order/list', data: { params: { page: this.params.page } } }).then((res) => { if(res.code === 0){ let list = res.list.item_list.map((item, index) => { item.key = index; return item; }); this.setState({ list:list, selectedRowKeys: [],//重置 pagination:Utils.pagination(res,(current)=>{ _this.params.page = current; _this.requestList(); }) }) } }) } //订单结束确认 handleConfirm = () => { let item = this.state.selectedItem; if(!item){ Modal.info({ title: '信息', content: '请选择一条订单进行结束' }) return; } axios.ajax({ url: '/order/ebike_info', data: { params: { orderId: item.id } } }).then((res) => { if(res.code === 0 ){ this.setState({ orderInfo: res.list, orderConfirmVisible: true }) } }) } //结束订单 handleFinishOrder = () => { let item = this.state.selectedItem; axios.ajax({ url: '/order/finish_order', data: { params: { orderId: item.id } } }).then((res) => { if(res.code === 0){ message.success('订单结束成功') this.setState({ orderConfirmVisible: false }) this.requestList(); } }) } onRowClick = (record, index) => { let selectKey = [index]; this.setState({ selectedRowKeys: selectKey, selectedItem: record }) } //订单详情页 openOrderDetail = () => { let item = this.state.selectedItem; if(!item){ Modal.info({ title: '信息', content: '请先选择一条订单' }) return; } window.open(`/#/common/order/detail/${item.id}`,'_blank') } render(){ const columns = [ { title: '订单编号', dataIndex: 'order_sn' }, { title: '车辆编号', dataIndex: 'bike_sn' }, { title: '用户名', dataIndex: 'user_name' }, { title: '手机号', dataIndex: 'mobile' }, { title: '里程', dataIndex: 'distance', render(distance){ return distance/1000 + 'Km'; } }, { title: '行驶时长', dataIndex: 'total_time' }, { title: '状态', dataIndex: 'status' }, { title: '开始时间', dataIndex: 'start_time' }, { title: '结束时间', dataIndex: 'end_time' }, { title: '订单金额', dataIndex: 'total_fee' }, { title: '实付金额', dataIndex: 'user_pay' } ] const formItemLayout = { labelCol: { span: 5 }, wrapperCol: { span: 19 } } const selectedRowKeys = this.state.selectedRowKeys; const rowSelection = { type: 'radio', selectedRowKeys } return ( <div> <Card> <FilterForm /> </Card> <Card style={{marginTop:10}}> <Button type="primary" onClick={this.openOrderDetail}>订单详情</Button> <Button type="primary" style={{marginLeeft: 10}} onClick={this.handlConfirm}>结束订单</Button> </Card> <div className="content-wrap"> <Table bordered columns={columns} dataSource={this.state.list} pagination={this.state.pagination} rowSelection= {rowSelection} onRow={(record, index) => { return { onClick: () => { this.onRowClick(record, index); } } }} /> </div> <Modal title="结束订单" visible={this.state.orderConfirmVisible} onCancel={() => { this.setState({ orderConfirmVisible: false }) }} onOk={this.handleFinishOrder} width={600}> <Form layout="horizontal"> <FormItem label="车辆编号" {...formItemLayout}> {this.state.orderInfo.bike_sn} </FormItem> <FormItem label="剩余电量" {...formItemLayout}> {this.state.orderInfo.battery + '%'} </FormItem> <FormItem label="行程开始时间" {...formItemLayout}> {this.state.orderInfo.start_time} </FormItem> <FormItem label="当前位置" {...formItemLayout}> {this.state.orderInfo.location} </FormItem> </Form> </Modal> </div> ) } } //子组件一：选择表单 class FilterForm extends React.Component{ render(){ const { getFieldDecorator } = this.props.form; return ( <Form layout="inline"> <FormItem label="城市"> { getFieldDecorator('city_id')( <Select style={{width:100}} placeholder="全部" > <Option value="">全部</Option> <Option value="1">北京市</Option> <Option value="2">天津市</Option> <Option value="3">深圳市</Option> </Select> ) } </FormItem> <FormItem label="订单时间"> { getFieldDecorator('start_time')( <DatePicker showTime format="YYYY-MM-DD HH:mm:ss"/> ) } </FormItem> <FormItem style={{marginLeft: -10}}> { getFieldDecorator('end_time')( <DatePicker style={{marginLeft: 5}} showTime format="YYYY-MM-DD HH:mm:ss"/> ) } </FormItem> <FormItem label="订单状态"> { getFieldDecorator('status')( <Select style={{ width: 80 }} placeholder="全部" > <Option value="">全部</Option> <Option value="1">进行中</Option> <Option value="2">结束行程</Option> </Select> ) } </FormItem> <FormItem> <Button type="primary" style={{margin:'0 5px'}}>查询</Button> <Button>重置</Button> </FormItem> </Form> ); } } FilterForm = Form.create({})(FilterForm);
三、订单详情
- 跳转详情页
- pages->order->index.js中：【订单详情】按钮监听onClick事件，调用this.openOrderDetail()，跳转路由
//订单详情页 openOrderDetail = () => { let item = this.state.selectedItem; if(!item){ Modal.info({ title: '信息', content: '请先选择一条订单' }) return; } window.open(`/#/common/order/detail/${item.id}`,'_blank') }关键：window.open(`/#/common/order/detail/${item.id}`,'_blank')
-
src目录下：新建common.js，类似admin.js编写项目公共结构代码，负责路由详情页展示
import React from 'react' import { Row, Col } from 'antd'; import Header from './components/Header' import './style/common.less' export default class Common extends React.Component { render() { return ( <div> <Row className="simple-page"> <Header menuType="second"/> </Row> <Row className="content"> {this.props.children} </Row> </div> ); } }通过menuType：控制显示header组件的不同样式（components->header->index.js）
//其它代码 render() { const menuType = this.props.menuType; return ( <div className="header"> <Row className="header-top"> { menuType ? <Col span="6" className="logo"> <img src="/assets/logo-ant.svg" alt="" /> <span>LJQ 通用管理系统</span> </Col> : '' } <Col span={menuType ? 18 : 24}> <span>欢迎，{this.state.userName}</span> <a href='#'>退出</a> </Col> </Row> { menuType ? '' : <Row className="breadcrumb"> <Col span={4} className="breadcrumb-title"> 首页 </Col> <Col span={20} className="weather"> <span className="date">{this.state.sysTime}</span> <span className="weather-detail">晴转多云</span> </Col> </Row> } </div> ) }CSS样式：
//style->common.less ul,li{ list-style: none; } .clearfix{ &::after{ content:''; clear: both; display: block; visibility: hidden; } } .content{ padding: 20px } //components->header->index.less //.common 页面简单头 .simple-page{ .header-top{ background: #1890ff; color: @colorM; } .ant-form, .ant-col-12, .weather{ display: none; } } //引入pages->order->detail.less -
router.js中：引入Common组件，使用<Route />的render方法定义嵌套路由
<Route path="/common" render={() => <Common> <Route path="/common/order/detail/:orderId" component={OrderDetail} /> </Common> }/>
