How to implement sharing function in uniapp

With the popularity of mobile Internet, the sharing function has become one of the necessary functions for various applications. In mobile application development, how to implement an easy-to-use and highly compatible sharing function is one of the problems that programmers need to solve. This article will introduce the detailed process of using the uniapp framework to implement the sharing function.

1. Preparation work

Before you start writing code, you need to prepare the following work:

1. Get the appid
Before using the WeChat sharing function, you need to first Register the application on the WeChat open platform and obtain the appid. For the specific acquisition process, please refer to the relevant documents of the WeChat open platform.

2. Introducing the official jssdk

The official jssdk is a set of js interfaces provided by WeChat for implementing WeChat web development. When using uniapp to implement the WeChat sharing function, you need to introduce the official jssdk into the project first. It can be introduced in the following ways:

In uniapp, it is recommended to place the official jssdk in the static folder.

2. Install plug-ins

In uniapp, we can use plug-ins developed by community leaders to implement the WeChat sharing function, and we do not need to care about the specific details of plug-in implementation. This article chooses to use the "uni-share" plug-in. The specific installation process is as follows:

1. Open the project in HBuilderX and find the "Plug-in Market" option in the left navigation bar.

2. Enter "uni-share" in the search box and click "Install".

3. Wait for the download and installation to complete, then reopen the project.

3. Code implementation

Next, implement the work prepared in the above steps in the code.

1. Introduce official jssdk

In the vue component that needs to use the WeChat sharing function, you first need to introduce the official jssdk:

import wx from 'weixin-js-sdk';

2. Initialize jssdk

Since the WeChat sharing function requires the use of the official jssdk, we need to initialize the jssdk when the component is loaded. Among them, we need to use the appid we obtained in the first step. Moreover, in order to ensure compatibility, it is recommended to use http request method to obtain jssdk related configuration parameters in the project.

import { getJssdk } from '@/api/wechat'; // http请求获取jssdk配置参数

export default {
  data() {
    return {
      shareData: { // 分享到朋友圈的内容
        title: '分享到朋友圈的标题',
        desc: '分享到朋友圈的描述',
        imgUrl: '分享到朋友圈的图片'
      },
      jssdkData: {} // jssdk相关配置参数
    }
  },
  mounted() {
    this.getJssdk();
  },
  methods: {
    async getJssdk() {
      const url = location.href.split('#')[0];
      const res = await getJssdk({
        url: url
      });
      this.jssdkData = res.data;
      wx.config({
        appId: this.jssdkData.appId,
        timestamp: this.jssdkData.timestamp,
        nonceStr: this.jssdkData.nonceStr,
        signature: this.jssdkData.signature,
        jsApiList: ['updateAppMessageShareData', 'updateTimelineShareData'] // 配置需要使用微信分享的接口
      });
      wx.ready(() => {
        this.onWxReady(); // 初始化成功后回调函数
      });
    },
    onWxReady() {
      wx.updateAppMessageShareData({
        title: this.shareData.title,
        desc: this.shareData.desc,
        link: location.href,
        imgUrl: this.shareData.imgUrl,
        success: () => {
          // 分享到朋友成功后回调函数
        }
      });
      wx.updateTimelineShareData({
        title: this.shareData.title,
        link: location.href,
        imgUrl: this.shareData.imgUrl,
        success: () => {
          // 分享到朋友圈成功后回调函数
        }
      });
    }
  }
}

3. Calling the plug-in

The plug-in "uni-share" encapsulates the WeChat sharing function and provides the "share" method for our convenience. Therefore, on the page we need to share, we only need to reference the plug-in and call the "share" method. The code is as follows:

import share from '@/uni_modules/uni-share/js_sdk/index';

export default {
  data() {
    return {
      shareData: { // 分享到朋友圈的内容
        title: '分享到朋友圈的标题',
        desc: '分享到朋友圈的描述',
        imgUrl: '分享到朋友圈的图片'
      }
    }
  },
  methods: {
    onShare(type) { // type为1表示分享到朋友，2表示分享到朋友圈
      share.share({
        type: 'weixin', // 分享到的平台，目前只支持微信
        data: {
          title: this.shareData.title,
          summary: this.shareData.desc,
          url: location.href,
          image: [this.shareData.imgUrl]
        },
        success: () => {
          console.log('分享成功');
        },
        fail: () => {
          console.log('分享失败');
        }
      });
    }
  }
}

4. Summary

Through the above steps, we have successfully used the uniapp framework Implemented WeChat sharing function. In general, although there are many steps, it is not difficult to implement. If we encounter problems during the implementation of the sharing function, we can refer to the uniapp official documentation or the development documentation of related plug-ins. hope that it can help us.
