How to implement online ticket purchasing and ticket management in uniapp

Uniapp is a cross-platform application framework developed based on Vue.js, which can be used to develop applications for multiple platforms such as Web, App, and small programs. Online ticket purchasing and ticket management can be implemented in Uniapp through the following steps.

1. Create a page: In Uniapp, use the vue-cli tool to create a page, name it Ticket.vue, and configure routing in the pages.json file.

2. Implement the ticket purchase function: In Ticket.vue, you can use template syntax for layout and interaction, and combine the components and API provided by uniapp to implement the ticket purchase function. Specific code examples are as follows:

   <template>
     <view>
       <button @click="chooseSeat">选择座位</button>
       <view v-if="showSeat">
         <view class="seat" v-for="seat in seats" :key="seat.id">
           <text>{{ seat.name }}</text>
           <text>{{ seat.price }}</text>
           <button @click="selectSeat(seat)">选座</button>
         </view>
       </view>
       <view v-if="selectedSeat">
         <button @click="payTicket">支付</button>
       </view>
     </view>
   </template>
   
   <script>
   export default {
     data() {
       return {
         showSeat: false, // 是否显示座位选择
         seats: [], // 座位列表
         selectedSeat: null // 已选座位
       }
     },
     methods: {
       chooseSeat() {
         // 发起接口请求获取座位列表
         // 示例代码，需要替换为真实的接口请求
         this.seats = [
           { id: 1, name: 'A1', price: 100 },
           { id: 2, name: 'A2', price: 100 },
           { id: 3, name: 'A3', price: 100 },
           // ...
         ]
         this.showSeat = true;
       },
       selectSeat(seat) {
         this.selectedSeat = seat;
       },
       payTicket() {
         // 发起接口请求进行支付
         // 示例代码，需要替换为真实的接口请求
         // 模拟支付成功
         uni.showToast({
           title: '支付成功',
           success() {
             // 跳转到订单详情页
             uni.navigateTo({
               url: '/pages/orderDetail.vue'
             })
           }
         })
       }
     }
   }
   </script>

3. Implementing ticket management functions: In Uniapp, ticket management functions can be implemented by requesting the back-end interface, including operations such as querying orders and refunding tickets. The specific code examples are as follows:

   <template>
     <view>
       <button @click="getOrders">查询订单</button>
       <view v-for="order in orders" :key="order.orderId">
         <text>{{ order.orderId }}</text>
         <text>{{ order.ticket }}</text>
         <button @click="refundTicket(order)">退票</button>
       </view>
     </view>
   </template>
   
   <script>
   export default {
     data() {
       return {
         orders: [] // 订单列表
       }
     },
     methods: {
       getOrders() {
         // 发起接口请求获取订单列表
         // 示例代码，需要替换为真实的接口请求
         this.orders = [
           { orderId: 1, ticket: 'A1' },
           { orderId: 2, ticket: 'B2' },
           { orderId: 3, ticket: 'C3' },
           // ...
         ]
       },
       refundTicket(order) {
         // 发起接口请求进行退票
         // 示例代码，需要替换为真实的接口请求
         // 模拟退票成功
         uni.showToast({
           title: '退票成功'
         })
       }
     }
   }
   </script>

The above code examples use Uniapp’s template syntax and API to implement the basic functions of online ticket purchase and ticket management. Specific interface requests and business logic need to be replaced with real code. You can select seats and pay on the ticket purchase page, and you can check orders and refund tickets on the ticket management page.
