一、点击小程序转发

1. 不加参数

 //转发onShareAppMessage: function() {let users = wx.getStorageSync('user');if (res.from === 'button') {}return {title: '转发',path: '/pages/index/index?from_uid=' + users.id,success: function(res) {}}} 

2.加入参数

 //转发onShareAppMessage: function() {let users = wx.getStorageSync('user');if (res.from === 'button') {}return {title: '转发',path: '/pages/index/index?from_uid=' + users.id,success: function(res) {}}} 

二、点击按钮分享

这个分享必须做成button 且加上open-type="share"

1.不加参数

 onShareAppMessage: function (res) {if (res.from === 'button') {}return {title: '转发',path: '/pages/index/community/topic/topic',success: function (res) {console.log('成功', res)}}}

2.加入参数

 //转发onShareAppMessage: function (res) {if (res.from === 'button') {}return {title: '转发',path: '/pages/index/community/topic/topic?jsonStr=' + this.data.list,success: function (res) {console.log('成功', res)}}}

onShareAppMessage与生命周期同级
