How to implement message push and notification in uniapp application
Oct 18, 2023 am 09:19 AM
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:
- Register an account on the Tencent Cloud Developer Platform and create an application.
- Install the uni-push plug-in in the Uniapp project. You can install it through the following command:
npm install @dcloudio/uni-push
- In
main.jsof the Uniapp project Introduce the uni-push plug-in and initialize it:
import UniPush from '@dcloudio/uni-push'
Vue.use(UniPush, {
// 在騰訊云開發(fā)者平臺(tái)上創(chuàng)建應(yīng)用時(shí)生成的 Secret ID
secretid: 'your_sceretid',
// 在騰訊云開發(fā)者平臺(tái)上創(chuàng)建應(yīng)用時(shí)生成的 Secret Key
secretkey: 'your_secretkey',
// 在騰訊云開發(fā)者平臺(tái)上創(chuàng)建應(yīng)用時(shí)生成的 SDK App ID
appid: 'your_appid',
// 推送通知的圖標(biāo)路徑（可選）
icon: '/static/logo.png',
// 推送通知的聲音路徑（可選）
sound: '/static/sound.mp3',
// 推送通知點(diǎn)擊后要打開的頁面路徑（可選）
page: '/pages/index'
})- Where push messages are required, call the
UniPush.pushMessagemethod to send push messages:
UniPush.pushMessage({
title: '消息標(biāo)題',
content: '消息內(nèi)容',
tokens: ['token1', 'token2'], // 推送目標(biāo)設(shè)備的token列表，可以是一個(gè)或多個(gè)token
// 其他可選參數(shù)，如自定義字段等
})- When the device receives a push message, you can listen to
getui inonLaunchoronShowinApp.vue. messageevent to handle push messages:
export default {
onLaunch(options) {
uni.$on('getui.message', message => {
// 處理推送消息
})
},
onShow(options) {
uni.$on('getui.message', message => {
// 處理推送消息
})
}
} 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:
- Where notifications need to be displayed, call the
uni.$notifymethod to display the notification. You can call it in a method in the component, or in Vue Called in the event callback function in the instance:
uni.$notify({
title: '通知標(biāo)題',
image: '/static/icon.png',
content: '通知內(nèi)容',
onClick() {
// 點(diǎn)擊通知的回調(diào)函數(shù)
},
onClose() {
// 關(guān)閉通知的回調(diào)函數(shù)
}
})- 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
createdlife 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.

What are the disadvantages of uniapp
Apr 06, 2024 am 04:06 AM
UniApp has many conveniences as a cross-platform development framework, but its shortcomings are also obvious: performance is limited by the hybrid development mode, resulting in poor opening speed, page rendering, and interactive response. The ecosystem is imperfect and there are few components and libraries in specific fields, which limits creativity and the realization of complex functions. Compatibility issues on different platforms are prone to style differences and inconsistent API support. The security mechanism of WebView is different from native applications, which may reduce application security. Application releases and updates that support multiple platforms at the same time require multiple compilations and packages, increasing development and maintenance costs.
How to turn off Apple TV keyboard reminders on iPhone

On AppleTV, if you don't want to use AppleTV Remote to enter text, you can type using a nearby iPhone or iPad. Whenever a text field appears on AppleTV, a notification will appear on your iPhone or iPad. After tapping the notification, you can use the on-screen keyboard on your iOS device to enter text on AppleTV. If you find these notifications annoying, you can disable them on your iPhone or iPad (if you have a few AppleTVs and kids at home, you'll know what we mean). If you're running iOS/iPadOS 15.1 or later, here's how to disable them. Launch on iPhone or iPad
What is the difference between uniapp and flutter
Apr 06, 2024 am 04:30 AM
UniApp is based on Vue.js, and Flutter is based on Dart. Both support cross-platform development. UniApp provides rich components and easy development, but its performance is limited by WebView; Flutter uses a native rendering engine, which has excellent performance but is more difficult to develop. UniApp has an active Chinese community, and Flutter has a large and global community. UniApp is suitable for scenarios with rapid development and low performance requirements; Flutter is suitable for complex applications with high customization and high performance.
