How to implement message push and notification in uniapp application

Uniapp is a cross-platform development framework based on Vue.js that can be used to develop applications that run on multiple platforms at the same time. When implementing message push and notification functions, Uniapp provides some corresponding plug-ins and APIs. The following will introduce how to use these plug-ins and APIs to implement message push and notification functions.

1. Message push
To implement the message push function, we can use the uni-push plug-in provided by Uniapp. This plug-in is based on Tencent Cloud Push Service and can push messages on multiple platforms. The following are the specific steps:

  1. Register an account on the Tencent Cloud Developer Platform and create an application.
  2. Install the uni-push plug-in in the Uniapp project. You can install it through the following command:
npm install @dcloudio/uni-push
  1. In main.js of the Uniapp project Introduce the uni-push plug-in and initialize it:
import UniPush from '@dcloudio/uni-push'

Vue.use(UniPush, {
  // 在腾讯云开发者平台上创建应用时生成的 Secret ID
  secretid: 'your_sceretid',
  // 在腾讯云开发者平台上创建应用时生成的 Secret Key
  secretkey: 'your_secretkey',
  // 在腾讯云开发者平台上创建应用时生成的 SDK App ID
  appid: 'your_appid',
  // 推送通知的图标路径(可选)
  icon: '/static/logo.png',
  // 推送通知的声音路径(可选)
  sound: '/static/sound.mp3',
  // 推送通知点击后要打开的页面路径(可选)
  page: '/pages/index'
})
  1. Where push messages are required, call the UniPush.pushMessage method to send push messages:
UniPush.pushMessage({
  title: '消息标题',
  content: '消息内容',
  tokens: ['token1', 'token2'], // 推送目标设备的token列表,可以是一个或多个token
  // 其他可选参数,如自定义字段等
})
  1. When the device receives a push message, you can listen to getui in onLaunch or onShow in App.vue. message event to handle push messages:
export default {
  onLaunch(options) {
    uni.$on('getui.message', message => {
      // 处理推送消息
    })
  },
  onShow(options) {
    uni.$on('getui.message', message => {
      // 处理推送消息
    })
  }
}

2. Notification
To implement the notification function, we can use the uni-notify plug-in provided by Uniapp. This plug-in is based on the Notification API of HTML5 browsers and can display notifications in the browser. The following are the specific steps:

  1. Where notifications need to be displayed, call the uni.$notify method to display the notification. You can call it in a method in the component, or in Vue Called in the event callback function in the instance:
uni.$notify({
  title: '通知标题',
  image: '/static/icon.png',
  content: '通知内容',
  onClick() {
    // 点击通知的回调函数
  },
  onClose() {
    // 关闭通知的回调函数
  }
})
  1. In the browser, when the user requests notification permission for the first time, the user needs to be asked whether to allow notifications. We can request notification permissions during the created life cycle of the Vue instance:
export default {
  created() {
    if (Notification.permission === 'default') {
      Notification.requestPermission()
    }
  }
}

In this way, the user will be asked whether to allow notifications when opening the application.

The above are the specific steps to use Uniapp to implement message push and notification. By using the uni-push plug-in and uni-notify plug-in, we can easily implement these two functions. Of course, in actual development, it can also be customized and expanded according to specific needs. Hope this article is helpful to you.
