Does uniapp support websocket?

Uni-app is a cross-platform development framework that supports the simultaneous generation of applications for Android, iOS, H5 and other platforms based on the same code. Its excellent performance and convenience and ease of use have been widely adopted by enterprises and developers. Pay attention and use. For application scenarios that require real-time two-way communication, WebSocket is undoubtedly a very good choice. So, does Uni-app support WebSocket?

The answer is yes.

Uni-app encapsulates WebSocket and provides plug-ins for use in Vue, which can help developers quickly implement WebSocket functions. The following is a simple example using WebSocket.

1. Introducing the plug-in

Uni-app’s encapsulation of WebSocket has been implemented in the plug-in, so we need to introduce the plug-in in main.js .

import Vue from 'vue'
import App from './App.vue'
import uwebsockets from 'uni-websocket-plugin'

Vue.config.productionTip = false

Vue.use(uwebsockets)

App.mpType = 'app'

const app = new Vue({
  ...App
})
app.$mount()

2. Using WebSocket

In components that need to use WebSocket, we can use this.$WebSocket to create a WebSocket instance.

<template>
  <view>
    <view>{{message}}</view>
    <button>发送消息</button>
  </view>
</template>

<script>
export default {
  data() {
    return {
      message: &#39;&#39;
    }
  },
  methods: {
    send() {
      this.$WebSocket.send({
        data: &#39;Hello World&#39;
      })
    }
  },
  onMessage(data) {
    this.message = data
  }
}
</script>

In the above code, we use the this.$WebSocket.send method to send a message to the WebSocket server, and receive the message returned by the server in the onMessage method , and display it on the page.

In general, Uni-app's support for WebSocket is very friendly and convenient, and can help developers implement various WebSocket-based application scenarios.
