How to implement message push and notification reminder in uniapp

With the rapid development of mobile Internet, message push and notification reminder have become essential in mobile applications Function. In uniapp, we can implement message push and notification reminders through some plug-ins and interfaces. This article will introduce a method to implement message push and notification reminder in uniapp, and provide specific code examples.

1. Message push

The premise of implementing message push is that we need a background service to send push messages. Here I recommend using JPush. Jiguang Push provides a wealth of interfaces and functions, suitable for the message push needs of various platforms. The following are the steps to use Aurora Push in uniapp:

1. Register an Aurora Push account and create an application: First, register an account on the Aurora Push official website and create an application. Obtain the AppKey of the application according to the guidelines of the official documentation.
2. Introducing plug-ins: In the uniapp project, we need to introduce the Aurora push plug-in. You can search for the "JPush" plug-in through the HBuilderX plug-in market and install it into the project. After the installation is complete, add the following code to the project's manifest.json file:

{
  "jpush": {
    "appKey": "your_app_key",
    "channel": "developer-default",
    "debug": false
  }
}

Among them, "your_app_key" needs to be replaced with your own AppKey.

3. Initialize and register aliases: Add the following code in the project's main.js file to initialize Aurora Push and register device aliases:

import { jpush } from 'uni-app-plus'

jpush.init({
  appKey: 'your_app_key',
  channel: 'developer-default',
  debug: false
})

jpush.setAlias({
  alias: 'your_alias',
  sequence: 'your_sequence'
})

Where, 'your_alias ' is an alias defined by yourself, 'your_sequence' is the operation sequence number, which can usually be set to 0.

4. Processing push messages: Add the following code in the project's App.vue file to process the received push messages:

import { jpush } from 'uni-app-plus'

jpush.addReceiveListener(function (data) {
  // 处理推送消息
  console.log(data)
})

At this point, the function of message push Already implemented. When a message is pushed, by calling the JPush interface, we can receive the corresponding push notification on the mobile phone.

2. Notification reminder

To implement the notification reminder function in uniapp, we need to use the uni.Notification interface. Through this interface, we can implement customized notification reminder styles, sounds, etc. The following are the steps to implement notification reminders in uniapp:

1. Introduce notification plug-in: In the uniapp project, we need to introduce the uniapp-plus-notification plug-in. The plug-in can be searched and installed through the HBuilderX plug-in market. After the installation is complete, add the following code to the manifest.json file of the project:

{
  "notification": {
    "title": "你的应用名称",
    "iconColor": "#FFFFFF",
    "cronExpression": "0 8 * * * ?",
    "autoClear": true,
    "ongoing": true
  }
}

Among them, "title" is the notification bar title, "iconColor" is the icon color, and "cronExpression" is the scheduled notification. Time expression, "autoClear" indicates whether the notification is automatically cleared, and "ongoing" indicates whether the notification continues to be displayed.

2. Send notification: Use uni.Notification interface to send notification. Where notifications need to be sent, call the following code to send notifications:

uni.showNotification({
  title: '通知标题',
  content: '通知内容',
  data: {
    url: 'your_url'
  }
})

Among them, 'your_url' is the link address that will jump after clicking on the notification.

Through the above steps, we can implement the functions of message push and notification reminder in uniapp. Using Jiguang push service, we can send push messages through the background; using the uni.Notification interface, we can send customized notifications. According to specific needs, the code can be flexibly adjusted and expanded to implement more complex message push and notification reminder functions.
