1.安装dva-cli
npm install dva-cli -g
2.创建应用
dva new dvadashboard
[dvadashboard为项目名]
3.安装mockjs
- npm install mockjs --save
4.配置mockjs
- 打开.roadhogrc.mock.js 设置如下
const fs=require('fs');
const path=require('path');
const mockPath=path.join(__dirname+'/mock');
const mock={};
fs.readdirSync(mockPath).forEach(file=>{
Object.assign(mock,require('./mock/'+file));
});
module.exports=mock;
5.模拟用户管理API
mock文件夹下新建user.js
API设置:
这里只模拟俩个api 1.获取所有用户数据 2.添加用户
const Mock=require('mockjs');
let db=Mock.mock({
'data|3-6':[{
id:'@id',
name:'@name',
'age|18-32':
}]
});
module.exports={
[`GET /api/users`](req,res){
res.status().json(db);
},
[`POST /api/users`](req,res){
let user=req.body;
console.log(req);
user.id=Mock.mock('@id');
db.data.push(user);
res.status().json(user);
}
}
接下来看一下api能不能使用， 进入项目目录， 执行 npm start 启动
进入默认页面 默认端口号 8000 如下是项目启动后默认页面
访问下api http://localhost:8000/api/users 好了，可以访问 成功返回模拟用户列表数据
6.安装antd
npm install antd babel-plugin-import --save
babel-plugin-import 是用来按需加载 antd 的脚本和样式的
安装完成后,配置使用antd 修改.roadhogrc文件
添加 ["import",{ "libraryName":"antd","style":"css" }] 最后文件如下所示：
{
"entry": "src/index.js",
"env": {
"development": {
"extraBabelPlugins": [
"dva-hmr",
"transform-runtime",
["import",{ "libraryName":"antd","style":"css" }]
]
},
"production": {
"extraBabelPlugins": [
"transform-runtime",
["import",{ "libraryName":"antd","style":"css" }]
]
}
}
}
7.定义路由
- 在src/routes/ 文件夹下新建 usersPage.js
这可能是最简单的一个页面了
import { connect } from 'dva';
const UserPage=()=>{
return (
<div>
<h1>UserPage</h1>
</div>
);
};
export default connect()(UserPage);
- 注册路由信息 修改src/router.js文件
顺手加了个组件动态加载
import React from 'react';
import { Router, Route, Switch } from 'dva/router';
import dynamic from 'dva/dynamic';
import IndexPage from './routes/IndexPage'; function RouterConfig({ history,app }) { const UserPage=dynamic({
app, component:()=>import('./routes/usersPage')
}); return (
<Router history={history}>
<Switch>
<Route path="/" exact component={IndexPage} />
<Route path="/users" exact component={UserPage} />
</Switch>
</Router>
);
} export default RouterConfig;
查看一下路由配置效果 访问http://localhost:8000/#/users
显示内容了
8.添加与服务端通讯
- 修改src/utils/request.js如下 用于提供基础的ajax数据访问
也有不少使用axio的 具体优缺点还没研究。
import fetch from 'dva/fetch';
const checkStatus=(response)=>{
if(response.status>= && response.status<=){
return response;
}
const error=new Error(response.statusText);
error.response=response;
throw error;
};
export default async function request(url,options={}) {
options.headers={
'Content-Type':'application/json'
}
const response=await fetch(url,options);
checkStatus(response);
const data=await response.json();
return data;
}
这里为了理解简单 省略一层 user.service (封装基础ajax通讯 提供业务接口) 在业务层中直接调用request里方法 【只是为了学习方便】
- 然后在src/models下新建user.js
import request from '../utils/request';
const User={
namespace:"user", state:{
list:[],
visibleModal:false
},
reducers:{
save(state,{ payload:{ data:list } }){ return {
...state,
list
};
}
},
effects:{
* query({},{ call,put }){
const { data }=yield call(request,'/api/users',{ method:'GET' });
yield put({type:'save',payload:{ data }});
},
* create({ payload:{ user } },{ call,put }){
yield call(request,'/api/users',{
body:JSON.stringify(user),
method:'POST'
});
yield put({type:'query',payload:{ }});
}
},
subscriptions:{
setup({ dispatch,history }){ console.log('running subscriptions ...');
return history.listen(({ pathname,search })=>{ console.log(`pathname: ${pathname}`);
dispatch({ type:'query'});
});
}
}
}; export default User;
这里主要体现dva对redux react-saga的封装处理 一目了然了
- 然后注册model 修改路由处代码为：
import React from 'react';
import { Router, Route, Switch } from 'dva/router';
import dynamic from 'dva/dynamic';
import IndexPage from './routes/IndexPage'; function RouterConfig({ history,app }) { const UserPage=dynamic({
app,
models:()=>[
import('./models/user')
],
component:()=>import('./routes/usersPage')
}); return (
<Router history={history}>
<Switch>
<Route path="/" exact component={IndexPage} />
<Route path="/users" exact component={UserPage} />
</Switch>
</Router>
);
} export default RouterConfig;
9.新建用户数据列表组件 使用antd的Tabel承载
顺手也把添加用户的表单建了吧
user.js
import { Table,Button } from 'antd';
import { connect } from 'dva';
import UserModal from './create';
const UserTable = ({ list,dispatch }) => {
const createUser=(user)=>{
dispatch({
type:'user/create',
payload:{
user
}
});
};
const columns=[
{
Title:'ID',
dataIndex:'id'
},
{
Title:'NAME',
dataIndex:'name'
},
{
Title:'AGE',
dataIndex:'age'
}
];
return (
<div>
<UserModal record={ {} } ok={ createUser }>
<Button type="primary">NEW</Button>
</UserModal>
<Table
columns={ columns }
dataSource={ list }
rowKey={ t=>t.id }
pagination={ false }>
{/* users datatable */}
</Table>
</div>
);
};
export default connect(({ user }) => {
console.log(user);
return {
list: user.list
};
})(UserTable);
create.js
import React,{ Component } from 'react';
import { Modal,Form,Input } from 'antd';
class UserModal extends Component{
constructor(props){
super(props);
this.state={
visible:false
};
}
render(){
const { children,form:{ getFieldDecorator },record,ok }=this.props;
const showModal=()=>{
this.setState({
visible:true
});
};
const hideModal=()=>{
this.setState({
visible:false
});
};
const save=()=>{
this.props.form.validateFields((err,val)=>{
//val ==> record
// console.log(val);
ok(val);
hideModal();
});
};
return (
<div>
<span onClick={ showModal }>
{ children }
</span>
<Modal
title="Create User"
visible={ this.state.visible }
onCancel={ hideModal }
onOk={ save }>
<Form>
<Form.Item label="Name">
{
getFieldDecorator('name', {
initialValue: record.name
})(<Input />)
}
</Form.Item>
<Form.Item>
{
getFieldDecorator('age',{
initialValue:record.age
})(<Input />)
}
</Form.Item>
</Form>
</Modal>
</div>
);
};
}
export default Form.create()(UserModal);
usersPage.js
import { connect } from 'dva';
import Main from '../components/layout/main';
import UserTable from '../components/user/user';
const UserPage=()=>{
return (
<Main>
<h1>UserPage</h1>
<UserTable />
</Main>
);
};
export default connect()(UserPage);
