移动端开发(体检预约)_2

1. 体检预约流程

用户可以通过如下操作流程进行体检预约:

1、在移动端首页点击体检预约,页面跳转到套餐列表页面

2、在套餐列表页面点击要预约的套餐,页面跳转到套餐详情页面

3、在套餐详情页面点击立即预约,页面跳转到预约页面

4、在预约页面录入体检人信息,包括手机号,点击发送验证码

5、在预约页面录入收到的手机短信验证码,点击提交预约,完成体检预约

2. 体检预约

2.1 页面调整

在预约页面(/pages/orderInfo.html)进行调整

2.1.1 展示预约的套餐信息

第一步:从请求路径中获取当前套餐的id

1
2
3
<script>
var id = getUrlParam("id");//套餐id
</script>

第二步:定义模型数据setmeal,用于套餐数据展示

var vue = new Vue({
el:'#app',
data:{
setmeal:{},//套餐信息
orderInfo:{
setmealId:id,
sex:'1'
}//预约信息
}
});
<div class="card">
<div class="">
<img :src="'http://pqjroc654.bkt.clouddn.com/'+setmeal.img" width="100%" height="100%" />
</div>
<div class="project-text">
<h4 class="tit">{{setmeal.name}}</h4>
<p class="subtit">{{setmeal.remark}}</p>
<p class="keywords">
<span>{{setmeal.sex == '0' ? '性别不限' : setmeal.sex == '1' ? '男':'女'}}</span>
<span>{{setmeal.age}}</span>
</p>
</div>
<div class="project-know">
<a href="orderNotice.html" class="link-page">
<i class="icon-ask-circle"><span class="path1"></span><span class="path2"></span></i>
<span class="word">预约须知</span>
<span class="arrow"><i class="icon-rit-arrow"></i></span>
</a>
</div>
</div>

第三步:在VUE的钩子函数中发送ajax请求,根据id查询套餐信息

1
2
3
4
5
mounted(){
axios.post("/setmeal/findById.do?id=" + id).then((response) => {
this.setmeal = response.data.data;
});
}

2.1.2 手机号校验

第一步:在页面导入的healthmobile.js文件中已经定义了校验手机号的方法

/**
* 手机号校验
1--以1为开头;
2--第二位可为3,4,5,7,8,中的任意一位;
3--最后以0-9的9个整数结尾。
*/
function checkTelephone(telephone) {
var reg=/^[1][3,4,5,7,8][0-9]{9}$/;
if (!reg.test(telephone)) {
return false;
} else {
return true;
}
}

第二步:为发送验证码按钮绑定事件sendValidateCode

<div class="input-row">
<label>手机号</label>
<input v-model="orderInfo.telephone"
type="text" class="input-clear" placeholder="请输入手机号">
<input style="font-size: x-small;"
id="validateCodeButton" @click="sendValidateCode()" type="button" value="发送验证码">
</div>
//发送验证码
sendValidateCode(){
//获取用户输入的手机号
var telephone = this.orderInfo.telephone;
//校验手机号输入是否正确
if (!checkTelephone(telephone)) {
this.$message.error('请输入正确的手机号');
return false;
}
}

2.1.3 30秒倒计时效果

前面在sendValidateCode方法中进行了手机号校验,如果校验通过,需要显示30秒倒计时效果

//发送验证码
sendValidateCode(){
//获取用户输入的手机号
var telephone = this.orderInfo.telephone;
//校验手机号输入是否正确
if (!checkTelephone(telephone)) {
this.$message.error('请输入正确的手机号');
return false;
}
validateCodeButton = $("#validateCodeButton")[0];
clock = window.setInterval(doLoop, 1000); //一秒执行一次
}

其中,validateCodeButton和clock是在healthmobile.js文件中定义的变量,doLoop是在healthmobile.js文件中定义的方法

var clock = '';//定时器对象,用于页面30秒倒计时效果
var nums = 30;
var validateCodeButton;
//基于定时器实现30秒倒计时效果
function doLoop() {
validateCodeButton.disabled = true;//将按钮置为不可点击
nums--;
if (nums > 0) {
validateCodeButton.value = nums + '秒后重新获取';
} else {
clearInterval(clock); //清除js定时器
validateCodeButton.disabled = false;
validateCodeButton.value = '重新获取验证码';
nums = 30; //重置时间
}
}

2.1.4 发送ajax请求

在按钮上显示30秒倒计时效果的同时,需要发送ajax请求,在后台给用户发送手机验证码

//发送验证码
sendValidateCode(){
//获取用户输入的手机号
var telephone = this.orderInfo.telephone;
//校验手机号输入是否正确
if (!checkTelephone(telephone)) {
this.$message.error('请输入正确的手机号');
return false;
}
validateCodeButton = $("#validateCodeButton")[0];
clock = window.setInterval(doLoop, 1000); //一秒执行一次
axios.post("/validateCode/send4Order.do?telephone=" + telephone).then((response) => {
if(!response.data.flag){
//验证码发送失败
this.$message.error('验证码发送失败,请检查手机号输入是否正确');
}
});
}

创建ValidateCodeController,提供方法发送短信验证码,并将验证码保存到redis

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import redis.clients.jedis.Jedis;
import redis.clients.jedis.JedisPool;
import java.util.Random;

/**
* 短信验证码
*/
@RestController
@RequestMapping("/validateCode")
public class ValidateCodeController {
@Autowired
private JedisPool jedisPool;

//体检预约时发送手机验证码
@RequestMapping("/send4Order")
public Result send4Order(String telephone){
Integer code = ValidateCodeUtils.generateValidateCode(4);//生成4位数字验证码
try {
//发送短信
SMSUtils.sendShortMessage(SMSUtils.VALIDATE_CODE,telephone,code.toString());
} catch (ClientException e) {
e.printStackTrace();
//验证码发送失败
return new Result(false, MessageConstant.SEND_VALIDATECODE_FAIL);
}
System.out.println("发送的手机验证码为:" + code);
//将生成的验证码缓存到redis
jedisPool.getResource().setex(
telephone + RedisMessageConstant.SENDTYPE_ORDER,5 * 60,code.toString());
//验证码发送成功
return new Result(true,MessageConstant.SEND_VALIDATECODE_SUCCESS);
}
}

2.1.5 日历展示

页面中使用DatePicker控件来展示日历。根据需求,最多可以提前一个月进行体检预约,所以日历控件只展示未来一个月的日期

<div class="date">
<label>体检日期</label>
<i class="icon-date" class="picktime"></i>
<input v-model="orderInfo.orderDate" type="text" class="picktime" readonly>
</div>
<script>
//日期控件
var calendar = new datePicker();
calendar.init({
'trigger': '.picktime',/*按钮选择器,用于触发弹出插件*/
'type': 'date',/*模式:date日期;datetime日期时间;time时间;ym年月;*/
'minDate': getSpecifiedDate(new Date(),1),/*最小日期*/
'maxDate': getSpecifiedDate(new Date(),30),/*最大日期*/
'onSubmit': function() { /*确认时触发事件*/},
'onClose': function() { /*取消时触发事件*/ }
});
</script>

其中getSpecifiedDate方法定义在healthmobile.js文件中

1
2
3
4
5
6
7
8
//获得指定日期后指定天数的日期
function getSpecifiedDate(date,days) {
date.setDate(date.getDate() + days);//获取指定天之后的日期
var year = date.getFullYear();
var month = date.getMonth() + 1;
var day = date.getDate();
return (year + "-" + month + "-" + day);
}

2.1.6 提交预约请求

<div class="box-button">
<button @click="submitOrder()" type="button" class="btn order-btn">提交预约</button>
</div>
//提交预约
submitOrder(){
//校验身份证号格式
if(!checkIdCard(this.orderInfo.idCard)){
this.$message.error('身份证号码输入错误,请重新输入');
return ;
}
axios.post("/order/submit.do",this.orderInfo).then((response) => {
if(response.data.flag){
//预约成功,跳转到预约成功页面
window.location.href="orderSuccess.html?orderId=" + response.data.data;
}else{
//预约失败,提示预约失败信息
this.$message.error(response.data.message);
}
});
}

其中checkIdCard方法是在healthmobile.js文件中定义的

11
12
/**
* 身份证号码校验
* 身份证号码为15位或者18位,15位时全为数字,18位前17位为数字,最后一位是校验位,可能为数字或字符X
*/
function checkIdCard(idCard){
var reg = /(^\d{15}$)|(^\d{18}$)|(^\d{17}(\d|X|x)$)/;
if(reg.test(idCard)){
return true;
}else{
return false;
}
}

@RequestMapping("/submit")
public Result submitOrder(@RequestBody Map map){
String telephone = (String) map.get("telephone");
//从Redis中获取缓存的验证码,key为手机号+RedisConstant.SENDTYPE_ORDER
String codeInRedis = jedisPool.getResource().get(

String validateCode = (String) map.get("validateCode");
//校验手机验证码
if(codeInRedis == null || !codeInRedis.equals(validateCode)){
return new Result(false, MessageConstant.VALIDATECODE_ERROR);
}
Result result =null;
//调用体检预约服务
try{
map.put("orderType", Order.ORDERTYPE_WEIXIN);
result = orderService.order(map);
}catch (Exception e){
e.printStackTrace();
//预约失败
return result;
}
if(result.isFlag()){
//预约成功,发送短信通知
String orderDate = (String) map.get("orderDate");
try {
SMSUtils.sendShortMessage(SMSUtils.ORDER_NOTICE,telephone,orderDate);
} catch (ClientException e) {
e.printStackTrace();
}
}
return result;
}
}

2.2.2 服务接口

在health_interface工程中创建体检预约服务接口OrderService并提供预约方法

import com.itheima.entity.Result;
import java.util.Map;
/**
* 体检预约服务接口
*/
public interface OrderService {
//体检预约
public Result order(Map map) throws Exception;
}

2.2.3 服务实现类

在health_service_provider工程中创建体检预约服务实现类OrderServiceImpl并实现体检预约方法。

体检预约方法处理逻辑比较复杂,需要进行如下业务处理:

1、检查用户所选择的预约日期是否已经提前进行了预约设置,如果没有设置则无法进行预约

2、检查用户所选择的预约日期是否已经约满,如果已经约满则无法预约

3、检查用户是否重复预约(同一个用户在同一天预约了同一个套餐),如果是重复预约则无法完成再次预约

4、检查当前用户是否为会员,如果是会员则直接完成预约,如果不是会员则自动完成注册并进行预约

5、预约成功,更新当日的已预约人数

实现代码如下:

3. 预约成功页面展示

前面已经完成了体检预约,预约成功后页面会跳转到成功提示页面(orderSuccess.html)并展示预约的相关信息(体检人、体检套餐、体检时间等)。

/**
* 根据id查询预约信息,包括套餐信息和会员信息
* @param id

*/
@RequestMapping("/findById")
public Result findById(Integer id){
try{
Map map = orderService.findById(id);
//查询预约信息成功
return new Result(true,MessageConstant.QUERY_ORDER_SUCCESS,map);
}catch (Exception e){
e.printStackTrace();
//查询预约信息失败
return new Result(false,MessageConstant.QUERY_ORDER_FAIL);
}
}

3.2.2 服务接口

在OrderService服务接口中扩展findById方法

//根据id查询预约信息,包括体检人信息、套餐信息
public Map findById(Integer id) throws Exception;

3.2.3 服务实现类

if(map != null){
//处理日期格式
Date orderDate = (Date) map.get("orderDate");
map.put("orderDate",DateUtils.parseDate2String(orderDate));
}
return map;
}

3.2.4 Dao接口

在OrderDao接口中扩展findById4Detail方法
