小程序onShareTimeline()分享朋友圈

目前小程序分享到朋友圈有以下2个限制：

a.仅支持Android平台，ios平台暂不支持
b.微信基础库限制2.11.3及以上

开发者设置分享小程序到朋友圈，有2种方式：

1. wx.showShareMenu()，支持快速分享到朋友圈使用默认小程序标题，分享图为小程序logo，不可自定义参数。（uni-app已支持）

wx.showShareMenu({
  menus: ['shareAppMessage', 'shareTimeline'] //shareAppMessage必须得有
})

2. onShareTimeline()，支持自定义分享到朋友圈的小程序标题、分享图，自定义query参数。（uni-app截止发文暂不支持）

//注意必须得设置允许“发送给朋友”onShareAppMessage，是设置onShareTimeline的前提，否则不支持分享到朋友圈
onShareAppMessage: () => {
},
onShareTimeline: () => {
  return {
    title: "测试小程序朋友圈分享",
    query: "id=110101&name=heyzqt",
    imageUrl: "https://example.cn/test.png"
  }
},

单页模式

用户在朋友圈打开分享的小程序页面，虽然是小程序里的一个页面，但是不会真正打开小程序，可以理解成只用来预览的一个单页。

 

Page({
	//页面的初始数据
	data:{
	},
	//自定义函数
	// 用户点击右上角分享给好友,要先在分享好友这里设置menus的两个参数,才可以分享朋友圈
	onShareAppMessage: function() {
		wx.showShareMenu({
	      withShareTicket: true,
	      menus: ['shareAppMessage', 'shareTimeline']
	    })
	},
	//用户点击右上角分享朋友圈
	onShareTimeline: function () {
		return {
	      title: '',
	      query: {
	        key: value
	      },
	      imageUrl: ''
	    }
	},
	//生命周期函数--监听页面加载
    onLoad: function(options) {
    },
})
