How UniApp implements news information and hot spot push

UniApp’s method of implementing news information and hot spot push

With the rapid development of the mobile Internet, news information and hot spot push have become important ways for people to obtain information. UniApp is a cross-platform development framework based on Vue.js, which can achieve the effect of writing once and running on multiple terminals. In UniApp, we can use its rich component and plug-in ecosystem to realize the display of news information and hot push functions.

1. News information display

1. Create page

First, we need to create a page in UniApp to display news information. Create a News.vue file in the pages directory and add the following code in it:

<template>
  <view>
    <view class="news-title">{{ news.title }}</view>
    <view class="news-content">{{ news.content }}</view>
  </view>
</template>

<script>
export default {
  data() {
    return {
      news: { // 假设这是一个后端返回的新闻对象
        title: 'UniApp实现新闻资讯展示',
        content: 'UniApp是一种基于Vue.js的跨平台开发框架，可以实现一次编写多端运行的效果。'
      }
    }
  }
}
</script>

<style>
.news-title {
  font-size: 24px;
  font-weight: bold;
  margin-bottom: 10px;
}

.news-content {
  font-size: 14px;
  line-height: 1.5;
}
</style>

2. Routing configuration

In the index.js file in the router directory, Configure the routing information of the News page as follows:

export default [
  {
    path: '/news',
    name: 'News',
    component: () => import('@/pages/News.vue')
  }
]

3. Page jump

In other pages, jump to the News page through the uni.navigateTo method. As shown below:

uni.navigateTo({
  url: '/pages/news/news'
})

Through the above steps, we can realize the display function of news information in UniApp.

2. Hot push push

1. Integrated third-party push service

UniApp provides plug-ins such as uni-ali-push and uni-umeng-push. Hotspot push function can be realized. We can select and integrate suitable plug-ins according to our needs. Here we take uni-ali-push as an example.

First, open the uni-ali-push plug-in in HBuilderX and configure and initialize it according to the plug-in's documentation.

2. Register device

In the App.vue file, add the following code to register the device:

export default {
  async onLaunch() {
    const [error, res] = await uniCloud.callFunction({
      name: 'registerDevice',
      data: {
        // 设备信息
      }
    })
    if (error) {
      console.log('注册设备失败', error)
    } else {
      console.log('注册设备成功', res)
    }
  }
}

Among them, registerDevice is a custom cloud function Name, used to register device information.

3. Receive push messages

In the App.vue file, add the following code to receive push messages:

export default {
  async onShow() {
    const [error, res] = await uniCloud.callFunction({
      name: 'getPushMessage',
      data: {
        // 用户标识
      }
    })
    if (error) {
      console.log('获取推送消息失败', error)
    } else {
      console.log('推送消息', res)
    }
  }
}

Among them, getPushMessage is customized The name of the cloud function used to obtain push messages.

Through the above steps, we can implement the hotspot push function in UniApp.
