小程序实现自定义分享微信好友及微信朋友圈

首先在全局page.json中添加"shareAppMessage": true

{
    
    
		"path": "pages/brandCoupon/brandCoupon",
		"style": {
    
    
			"navigationBarTitleText": "霸王餐",
			"navigationStyle": "custom",
			"enablePullDownRefresh":true,
			"shareAppMessage": true
			}
	},

然后在组件中指定按钮类型为share分享类型

通过v-bind:data-bargainGood绑定并传入给onShareAppMessage分享微信好友后要显示的内容

title表示分享后展示的文本信息
imageUrl表示展示的图片
path表示点击分享的链接要跳转到的页面

<button open-type="share" v-bind:data-bargainGood="{goodsname, spdetailImg,origin_price,refer_price}" class="share">
	<view class="discount">邀请帮砍<image
	src="https://ebk-picture.oss-cn-hangzhou.aliyuncs.com/mini-wx/images/bargain/share.png"
	mode=""></image>
	</view>
	<view class="mustPrice">最低砍至{
    
    {
    
    bestPrice}}元</view>
</button>

注意：如果在组件中配置了withShareTicket为true，转到微信之后长按不会出现转发按钮

 wx.showShareMenu({
    
    
    withShareTicket: true, // 是否使用带 shareTicket 的转发
    menus: ['shareAppMessage'] // 可以指定分享到朋友圈、群等的菜单列表，默认为['shareAppMessage', 'shareTimeline']
  });

		onShareAppMessage(e) {
    
    
			console.log(e)
			var {
    
    goodsname,goodsId, spdetailImg,origin_price,refer_price}=this
				// console.log(e.target.dataset,'onShareAppMessage');	
			let userId = uni.getStorageSync('userInfo').uid
			 refer_price = '原价'+refer_price/100+'元';
			 origin_price = '售价'+ origin_price/100+'元'
			// let already_grade_amount = '当前'+e.target.dataset.bargaingood.already_grade_amount/100+'元'
			return {
    
    
				title:`${
    
    refer_price}, ${
    
    origin_price},${
    
    goodsname}`,
				imageUrl:this.spImgList[0],
				path:'pages/bargain/bargainspDetail?uid='+userId+'&goodsId='+goodsId
				}
		},

onShareTimeline(e){
    
    
			console.log(e,'分享微信')
			var {
    
    goodsname,goodsId, spdetailImg,origin_price,refer_price,already_grade_amount}=this
				// console.log(e.target.dataset,'onShareAppMessage');	
			let userId = uni.getStorageSync('userInfo').uid
			 refer_price = '原价'+refer_price/100+'元';
			 already_grade_amount = '现价'+(parseInt(origin_price) - parseInt(already_grade_amount))/100+'元'
			// let already_grade_amount = '当前'+e.target.dataset.bargaingood.already_grade_amount/100+'元'
			return {
    
    
				title:`${
    
    refer_price}, ${
    
    already_grade_amount},${
    
    goodsname}`,
				imageUrl:this.spImgList[0],
				path:'pages/bargain/bargainspDetail?uid='+userId+'&goodsId='+goodsId
				}
		},
