How to implement sharing and forwarding functions in uniapp

With the rapid development of mobile Internet, sharing and forwarding functions play an increasingly important role in APP . In uniapp, implementing sharing and forwarding functions can increase the user experience and promotion effect of the APP. This article will introduce how to implement sharing and forwarding functions through uniapp, and provide specific code examples.

1. Implementation of sharing function

1. Introduction of sharing module
   First, introduce the uni-share module in the uniapp project. Add the following code to the main.js file of the project:

import uniShare from '@/uni_modules/uni-share/uni-share.js'
Vue.prototype.uniShare = uniShare

2. Define sharing method
   In the page that needs to be shared, define a sharing method. For example, add the following code to the index.vue file on the homepage:

methods: {
  onShare() {
    this.uniShare.showShareMenu({
      withShareTicket: true,
      success: res => {
        console.log('showShareMenu success', res)
      },
      fail: err => {
        console.error('showShareMenu error', err)
      }
    })
  }
}

3. Trigger sharing method
   Call the sharing method where sharing needs to be triggered. For example, add a share button to the index.vue file on the homepage and bind the click event:

<template>
  <view>
    <button @click="onShare">点击分享</button>
  </view>
</template>

2. Implementation of forwarding function

1. Introducing the forwarding module
   Introduce the forwarding function of the uni-share module into the uniapp project. Add the following code to the main.js file of the project:

import uniShare from '@/uni_modules/uni-share/uni-share.js'
Vue.prototype.uniShare = uniShare

2. Define forwarding method
   In the page where forwarding needs to be implemented, define a forwarding method. For example, add the following code to the detail.vue file on the product details page:

methods: {
  onShareAppMessage(options) {
    console.log('onShareAppMessage', options)
    return {
      title: '分享标题',
      path: '/pages/detail?id=' + this.goodsId,
      imageUrl: 'https://example.com/image.jpg',
      success: res => {
        console.log('分享成功', res)
      },
      fail: err => {
        console.error('分享失败', err)
      }
    }
  }
}

3. Trigger forwarding method
   Where you need to trigger forwarding, such as the bottom of the product details page, call Forward method and show forward button. For example, add the following code to the detail.vue file:

<template>
  <view>
    <!-- 商品详情 -->
    <!-- ... -->

    <!-- 转发按钮 -->
    <button openType="share">转发</button>
  </view>
</template>

The above are the specific steps and sample code to implement the sharing and forwarding functions in uniapp. By introducing the sharing module and forwarding module, defining corresponding methods, and triggering these methods where needed, we can easily implement the sharing and forwarding functions and improve the user experience and promotion effect of the APP.
