uniapp implements how to use the network status monitoring library to monitor network connection status

Network connections play an important role in modern application development. In uniapp, implementing network status monitoring can help us capture changes in network connection status in time, so as to make corresponding processing and improve user experience. This article will introduce how to use the network status monitoring library to monitor network connection status and provide specific code examples.

1. Using the network status monitoring library in uniapp

In uniapp, we can use uni-app's more functional extension library uni-simple-router to implement network status monitoring. This library encapsulates network status monitoring and response, and provides a simple and easy-to-use interface.

The following are the steps to use uni-simple-router:

1. Install the uni-simple-router library, open the terminal in the project root directory, and execute the following command:

npm install --save uni-simple-router

2. Introduce uni-simple-router in main.js, import and register router:

import Vue from 'vue'
import App from './App'
import router from './router'
import { RouterMount } from 'uni-simple-router' // 引入uni-simple-router库

Vue.config.productionTip = false

App.mpType = 'app'

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

// 注册uni-simple-router
RouterMount(app, router)

3. Create a component named networkstatus.vue, and Implement network status monitoring in it:

<template>
  <view></view>
</template>

<script>
export default {
  name: 'networkstatus',
  created () {
    // 监听网络状态
    uni.getNetworkType({
      success: (res) => {
        this.onNetworkStatusChange(res.networkType)
      }
    })
    uni.onNetworkStatusChange((res) => {
      this.onNetworkStatusChange(res.networkType)
    })
  },
  methods: {
    onNetworkStatusChange (networkType) {
      // 在这里对不同的网络状态进行处理
      if (networkType === 'none') {
        console.log('网络未连接')
      } else {
        console.log('网络已连接')
      }
    }
  }
}
</script>

<style scoped></style>

4. Introduce the networkstatus component to the page that needs to monitor network status, and add it to the page:

<template>
  <view>
    <!-- 页面内容 -->
    <networkstatus></networkstatus>
  </view>
</template>

<script>
import networkstatus from '@/components/networkstatus.vue' // 引入networkstatus组件

export default {
  components: {
    networkstatus // 注册networkstatus组件
  }
}
</script>

This is it , we have completed the configuration and use of the network status monitoring library in uniapp.

2. Code Example Description

In the above example code, we use the uni-simple-router library to monitor and process network status. First, we use uni.getNetworkType in the created lifecycle function of the networkstatus.vue component to obtain the current network status, and call the onNetworkStatusChange function to process the network status. Then, we monitor network status changes through uni.onNetworkStatusChange and call the onNetworkStatusChange function to process the network status.

In the onNetworkStatusChange function, we perform corresponding processing according to different network statuses. When the network is not connected (networkType is 'none'), we can pop up a prompt box or perform other processing; when the network is connected, we can perform corresponding logical processing, such as sending requests, refreshing data, etc.

Through the above steps, we can monitor the network status in uniapp and make corresponding processing in different network status.

Summary

This article introduces the method of using the network status monitoring library to monitor the network connection status in uniapp, and provides detailed code examples. By monitoring network status, we can obtain changes in network connection status in a timely manner, so as to perform corresponding processing and improve user experience. I hope this article will be helpful to everyone in network status monitoring during uniapp development.
