Title: Detailed guide to implement food recommendation and ordering services in Uniapp

Introduction:
With the popularity of mobile Internet, food recommendation and ordering services have become an integral part of people's lives. In Uniapp, we can take advantage of its cross-platform features to easily implement food recommendation and ordering services. This article will introduce how to use Uniapp to implement these two functions, with code examples.

1. Implementation of food recommendation function
1. Data acquisition and storage:
First, we need to obtain food recommendation data and store it in the back-end server or cloud database. You can use front-end request tools such as Ajax and axios to send requests to the back-end to obtain data and store the data in the Vue instance.

Sample code:

// 在Vue实例中存储美食推荐数据
data() {
  return {
    recommendFoodList: [] // 美食推荐数据
  }
},
mounted() {
  // 发送GET请求获取美食推荐数据
  this.$http.get('/api/food/recommend').then(response => {
    this.recommendFoodList = response.data;
  }).catch(error => {
    console.log(error);
  });
}

2. Page display:
Use Vue instructions on the page to display food recommendation data. Data can be displayed using lists, carousels, etc. as needed.

Sample code:

<template>
  <view>
    <swiper autoplay indicator-dots indicator-color="#ffffff">
      <swiper-item v-for="(food, index) in recommendFoodList" :key="index">
        <image :src="food.imageUrl"></image>
      </swiper-item>
    </swiper>
  </view>
</template>

2. Implementation of food ordering service function
1. Data acquisition and storage:
Similar to the food recommendation function, we need to obtain the data of the food ordering service and Store it in a backend server or cloud database. Data can be retrieved and stored in the same way.

Sample code:

// 在Vue实例中存储订餐服务数据
data() {
  return {
    restaurantList: [] // 餐厅列表数据
  }
},
mounted() {
  // 发送GET请求获取餐厅列表数据
  this.$http.get('/api/restaurant/list').then(response => {
    this.restaurantList = response.data;
  }).catch(error => {
    console.log(error);
  });
}

2. Page display:
Use Vue instructions on the page to display restaurant list data. Data can be displayed using lists, cards, etc., and the corresponding ordering function can be called in click events.

Sample code:

<template>
  <view>
    <view v-for="(restaurant, index) in restaurantList" :key="index" @click="order(restaurant)">
      <image :src="restaurant.imageUrl"></image>
      <text>{{ restaurant.name }}</text>
    </view>
  </view>
</template>

3. Ordering function:
According to specific needs, we can call the ordering function when clicking on the restaurant item, such as jumping to the menu selection page or popping up the ordering function. Pop-ups.

Sample code:

methods: {
  order(restaurant) {
    // 跳转到选择菜品页面或弹出点餐弹窗
    uni.navigateTo({
      url: '/pages/order/index?restaurantId=' + restaurant.id
    });
  }
}
