How to implement reader and novel recommendations in uniapp

Title: Using UniApp to implement reader and novel recommendations

Introduction:
UniApp is a cross-platform application framework developed based on Vue.js. By using It provides multi-terminal unified development capabilities, and we can easily implement reader and novel recommendation functions. This article will detail how to implement these two functions in UniApp and provide corresponding code examples.

1. Implementation of reader function

1. Create page structure
   Create a page in UniApp and name it Reader. The page structure is as follows:

<template>
  <view class="reader">
    <!-- 阅读器内容显示区域 -->
    <view class="content">{{ content }}</view>

    <!-- 阅读器功能区域 -->
    <view class="footer">
      <!-- 前进按钮 -->
      <button class="prevBtn" @click="prevPage">上一页</button>

      <!-- 后退按钮 -->
      <button class="nextBtn" @click="nextPage">下一页</button>
    </view>
  </view>
</template>

<script>
export default {
  data() {
    return {
      content: '' // 阅读器内容
    }
  },
  methods: {
    prevPage() {
      // 上一页操作
    },
    nextPage() {
      // 下一页操作
    }
  }
}
</script>

<style>
.reader {
  height: 100vh;
  padding: 20px;
}

.content {
  height: 90%;
  font-size: 16px;
  line-height: 1.5;
}

.footer {
  display: flex;
  justify-content: space-between;
  padding-top: 20px;
}

.prevBtn,
.nextBtn {
  padding: 10px;
  background-color: #333;
  color: #fff;
}
</style>

2. Get novel data
   In the above code, we define a content attribute in data to display the content in the reader. We need to obtain the corresponding novel data in the prevPage and nextPage methods in the methods section. You can use the axios or uni.request method to make a network request to obtain the chapter content of the novel. The sample code is as follows:

methods: {
  prevPage() {
    uni.request({
      url: 'http://example.com/api/prevChapter',
      success: (res) => {
        this.content = res.data.content;
      }
    });
  },
  nextPage() {
    uni.request({
      url: 'http://example.com/api/nextChapter',
      success: (res) => {
        this.content = res.data.content;
      }
    });
  }
}

3. Page jump and data transfer
   In practical applications, we usually click on a novel in the novel list and then jump to the reader page , and pass the corresponding novel id or chapter id. You can use the uni.navigateTo method to jump to the page and pass data through the url parameter. The sample code is as follows:

onItemClick(novelId, chapterId) {
  uni.navigateTo({
    url: `/pages/reader/reader?novelId=${novelId}&chapterId=${chapterId}`
  });
}

In the Reader page, you can obtain the novelId and chapterId in the url parameter through the uni.getLaunchOptionsSync method.

2. Implementation of the novel recommendation function

1. Obtain the recommended list data
   In UniApp, we can use the uni.request method to send a network request to obtain the recommended novel list data . The sample code is as follows:

// 小说推荐页面代码
<template>
  <view class="recommend">
    <view v-for="novel in novelList" :key="novel.id" class="novelItem">
      <!-- 小说封面 -->
      <image class="coverImage" :src="novel.coverImageUrl"></image>

      <!-- 小说标题 -->
      <view class="title">{{ novel.title }}</view>
    </view>
  </view>
</template>

<script>
export default {
  data() {
    return {
      novelList: [] // 推荐小说列表数据
    }
  },
  mounted() {
    this.getNovelList();
  },
  methods: {
    getNovelList() {
      uni.request({
        url: 'http://example.com/api/recommendList',
        success: (res) => {
          this.novelList = res.data;
        }
      });
    }
  }
}
</script>

<style>
.recommend {
  padding: 20px;
}

.novelItem {
  display: flex;
  align-items: center;
  margin-bottom: 20px;
}

.coverImage {
  width: 100px;
  height: 150px;
  margin-right: 10px;
}

.title {
  font-size: 16px;
  color: #333;
}
</style>

2. Page jump and data transfer
   In the novel recommendation page, after clicking on a novel, it will usually jump to the corresponding reader page, and Pass the novel id and chapter id. You can use the uni.navigateTo method in the click event of novelItem to jump to the page and pass the data through the url parameter. The sample code is as follows:

onItemClick(novelId, chapterId) {
  uni.navigateTo({
    url: `/pages/reader/reader?novelId=${novelId}&chapterId=${chapterId}`
  });
}

The above is the sample code for using UniApp to implement the reader and novel recommendation functions. Through the above code examples, we can easily implement these two functions in UniApp and expand and optimize them according to specific needs. Hope this article helps you!
