How to implement message push function in uniapp

With the rapid development of mobile Internet, message push function has become an important way for users to obtain information. In uniapp, we can implement the message push function by using third-party plug-ins and push services of the platform. This article will introduce the steps to implement message push in uniapp, and attach corresponding code examples.

Step 1: Select a push platform
First of all, we need to choose a message push platform. Currently, the more commonly used ones are Jiguang Push, Getui, Tencent Pigeon, etc. These push platforms provide corresponding SDKs and APIs to facilitate our integration in uniapp. Taking Jiguang Push as an example, we need to register a developer account on the Jiguang Push official website and obtain the App Key and Master Secret.

Step 2: Install the plug-in
In uniapp, we can implement the message push function by introducing third-party plug-ins. Open the HBuilderX editor, click the plug-in market on the right toolbar, search for and install the corresponding push plug-in, take Jiguang Push as an example, search for and install the "JPush" plug-in.

Step 3: Configure App Key and Master Secret
In HBuilderX, find the manifest.json file in the project root directory, edit the file, and add the following code:

"jpush" : {
"appKey": "YOUR_APP_KEY",
"channel": "YOUR_CHANNEL",
"devMode": true
}

Replace YOUR_APP_KEY with what you push in Jiguang Push App Key obtained from the official website.

Step 4: Initialize push service
In the entry file main.js of uniapp, introduce and initialize the JPush plug-in, and configure the message click event. The code example is as follows:

import JPush from './common/JPush/jpush.js'

//Initialization
JPush.init()

//Configuration Callback function of message click event
JPush.onJPushOpenNotification((msg) => {
console.log("Click message", msg)
})

This way we are done Initialization and configuration of push services.

Step 5: Send push message
To send a push message on the server side, you need to call the API of the corresponding push platform for push. Taking Jiguang Push as an example, we can use the backend interface or the backend management platform to send messages. In uniapp, we can send push messages by calling the API of the JPush plug-in. The code example is as follows:

//Send a custom message
JPush.sendCustomMessage('Custom message test')

//Send a notification message
JPush.sendNotificationMessage('Notification Message test', {
title: 'Test title',
content: 'Test content',
extras: {

key1: 'value1',
key2: 'value2'

}
})

By calling the corresponding API, we can send custom messages and notification messages, and customize the title, content, and additional information carried by the message.

Step 6: Receive push messages
To receive push messages in uniapp, we need to register the message reception event in the page's life cycle function. The code example is as follows:

onShow() {
//Register message receiving event
JPush.onJPushReceiveMessage((msg) => {

console.log("接收消息", msg)

})
}

In this way, when the application enters the foreground, you can monitor the reception of push messages.

So far, we have completed the steps to implement the message push function in uniapp. By selecting the push platform, installing plug-ins, configuring App Key and Master Secret, initializing the push service, sending push messages and receiving push messages, we can easily implement the message push function in uniapp.
