Use uniapp to implement message notification function

Introduction
With the popularity and development of mobile applications, message notification has become one of the essential functions of modern mobile applications. . In the uniapp development framework, we can easily implement the message notification function and it is compatible on different platforms.

Functional requirements
We need to implement the following functions:

1. Push message notifications. When the user receives a new message, the relevant content can be displayed in the notification bar.
2. Display of message list, users can view historical messages and click to enter specific message details page.
3. Synchronization of the read status of messages. After the user views the unread message, the read status of the message can be marked as read.

Implementation steps

1. Configure push service
   We can use the plug-ins provided by uniapp, such as uni-push, jpush etc., to implement the message push service. According to different needs, corresponding plug-ins can be selected for configuration and integration.
2. Create a message list page
   In uniapp, we can use Vue's component development model to create a message list page. Use the v-for instruction on the page to render the message list, and use the v-on instruction to bind the message click event to realize the function of clicking to enter the details page.

Sample code:

<template>
  <view>
    <view v-for="(item, index) in messageList" :key="index" @click="navigateToDetail(item)">
      <text>{{ item.title }}</text>
    </view>
  </view>
</template>

<script>
export default {
  data() {
    return {
      messageList: [
        { title: '消息1', content: '这是消息1的内容', read: false },
        { title: '消息2', content: '这是消息2的内容', read: true },
        { title: '消息3', content: '这是消息3的内容', read: false }
      ]
    };
  },
  methods: {
    navigateToDetail(item) {
      // 点击进入消息详情页面，并处理已读状态
      if (!item.read) {
        item.read = true;
        // 发起接口请求，将消息的已读状态同步到服务器
      }
      uni.navigateTo({
        url: `/pages/message/detail?id=${item.id}`
      });
    }
  }
};
</script>

3. Create message details page
   In the message details page, we can display the specific message content, and after the page is loaded, Determine whether the message needs to be marked as read based on the read status.

Sample code:

<template>
  <view>
    <text>{{ message.title }}</text>
    <text>{{ message.content }}</text>
  </view>
</template>

<script>
export default {
  data() {
    return {
      message: {}
    };
  },
  onLoad(options) {
    // 根据消息id，查询消息详情
    const messageId = options.id;
    this.message = this.getMessageDetail(messageId);
    
    // 根据已读状态来处理消息标记
    if (!this.message.read) {
      this.message.read = true;
      // 发起接口请求，将消息的已读状态同步到服务器
    }
  },
  methods: {
    getMessageDetail(id) {
      // 发起接口请求，查询消息详情
      return {
        id: id,
        title: '消息标题',
        content: '消息内容',
        read: false
      };
    }
  }
};
</script>

Summary
Through the uniapp development framework, we can easily implement the message notification function. We can implement message push by configuring the push service, create message lists and message details pages through Vue's component development model, synchronize the read status of messages through interface requests, and display the corresponding message content. In this way, users can easily view and operate message notifications.
