商城用户地址模块可以通过node和vue来进行实现。本攻略将详细介绍如何使用node和vue实现商城用户地址模块,包括前端和后端的所有代码和示例。
前端部分
1.项目初始化
首先使用vue-cli进行项目初始化,具体步骤:
npm install -g vue-cli
vue init webpack address-module
2.样式开发
使用element-ui
搭建页面样式,具体步骤:
npm install element-ui --save
在main.js
中引入并注册组件:
import ElementUI from 'element-ui';
import 'element-ui/lib/theme-chalk/index.css';
Vue.use(ElementUI);
3.地址模块开发
在src/components
下创建AddressModule.vue
,编辑模板代码,示例代码:
<template>
<div>
<div v-if="!isEditable">
<span>{{address.province}}</span>
<span>{{address.city}}</span>
<span>{{address.area}}</span>
<span>{{address.detail}}</span>
</div>
<div v-else>
<el-select v-model="address.province" placeholder="省份" @change="handleChangeProvince">
<el-option v-for="province in provinces" :key="province.id" :label="province.name" :value="province.name"></el-option>
</el-select>
<el-select v-model="address.city" placeholder="城市" @change="handleChangeCity">
<el-option v-for="city in cities" :key="city.id" :label="city.name" :value="city.name"></el-option>
</el-select>
<el-select v-model="address.area" placeholder="区域">
<el-option v-for="area in areas" :key="area.id" :label="area.name" :value="area.name"></el-option>
</el-select>
<el-input v-model="address.detail" placeholder="详细地址"></el-input>
<el-button @click="handleSave">保存</el-button>
<el-button @click="handleCancel">取消</el-button>
</div>
</div>
</template>
<script>
export default {
name: 'AddressModule',
data() {
return {
isEditable: false,
provinces: [],
cities: [],
areas: [],
address: {
province: '',
city: '',
area: '',
detail: ''
}
}
},
methods: {
handleChangeProvince() {
// 根据选择的省份更新城市选项
// 代码省略
},
handleChangeCity() {
// 根据选择的城市更新区域选项
// 代码省略
},
handleSave() {
// 保存地址信息
// 代码省略
},
handleCancel() {
// 取消编辑
// 代码省略
}
}
}
</script>
对应的样式代码:
.el-select {
width: 150px;
margin-right: 10px;
}
.el-input {
width: 300px;
margin-right: 10px;
}
4.模块调用
在需要使用地址模块的页面中引用组件并传递地址信息,示例代码:
<template>
<div>
<address-module :address="address" @save="handleSaveAddress"></address-module>
</div>
</template>
<script>
import AddressModule from '@/components/AddressModule.vue';
export default {
name: 'AddressPage',
components: {
AddressModule
},
data() {
return {
address: {
province: '',
city: '',
area: '',
detail: ''
}
}
},
methods: {
handleSaveAddress() {
// 保存地址信息
// 代码省略
}
}
}
</script>
后端部分
1.项目初始化
使用express-generator
初始化项目,具体步骤:
npm install -g express-generator
express address-api
cd address-api
npm install
2.数据库配置
使用mysql
数据库存储地址信息,首先需要配置数据库连接信息,在config.js
中配置:
module.exports = {
db: {
host: 'localhost',
user: 'root',
password: '123456',
database: 'address_db'
}
}
3.地址信息存储
使用sequelize
操作数据库进行地址信息的存储,具体步骤:
npm install sequelize --save
npm install mysql2 --save
在models
文件夹下创建address.js
,示例代码:
const Sequelize = require('sequelize');
const sequelize = require('../util/database');
const Address = sequelize.define('address', {
id: {
type: Sequelize.INTEGER,
autoIncrement: true,
allowNull: false,
primaryKey: true
},
province: {
type: Sequelize.STRING,
allowNull: false
},
city: {
type: Sequelize.STRING,
allowNull: false
},
area: {
type: Sequelize.STRING,
allowNull: false
},
detail: {
type: Sequelize.STRING,
allowNull: false
}
});
module.exports = Address;
4.地址信息查询
在routes
文件夹下创建address.js
,示例代码:
const express = require('express');
const router = express.Router();
const db = require('../util/database');
const Address = require('../models/address');
router.get('/:id', (req, res, next) => {
const id = req.params.id;
Address.findByPk(id)
.then(address => {
res.json(address);
})
.catch(err => {
console.log(err);
res.sendStatus(500);
});
});
router.post('/', (req, res, next) => {
const address = req.body;
Address.create(address)
.then(() => {
res.sendStatus(200);
})
.catch(err => {
console.log(err);
res.sendStatus(500);
});
});
router.put('/:id', (req, res, next) => {
const id = req.params.id;
const address = req.body;
Address.update(address, { where: { id: id } })
.then(() => {
res.sendStatus(200);
})
.catch(err => {
console.log(err);
res.sendStatus(500);
});
});
router.delete('/:id', (req, res, next) => {
const id = req.params.id;
Address.destroy({ where: { id: id } })
.then(() => {
res.sendStatus(200);
})
.catch(err => {
console.log(err);
res.sendStatus(500);
});
});
module.exports = router;
5.模块调用
在数据处理的地方引用address.js
并监听端口,示例代码:
const express = require('express');
const cors = require('cors');
const bodyParser = require('body-parser');
const addressRoutes = require('./routes/address');
const config = require('./config');
const app = express();
app.use(cors());
app.use(bodyParser.json());
app.use('/address', addressRoutes);
app.listen(3000, () => {
console.log('Server is running on port 3000');
});
到此为止,我们已经完成了商城用户地址模块的所有代码实现。通过前后端的配合,用户可以完成地址信息的编辑和保存,同时后端会将地址信息存储到数据库中,便于以后的使用。
