微信小程序---转发分享功能

1. 转发---onShareAppMessage

//用户点击右上角分享
onShareAppMessage: function (res) {
    return {
      title: 'xxx',
      path: 'pages/index/index',
      imageUrl: "../../img/share.png"
    }
  }

3.带参数

onShareAppMessage: function (res) {
    var _this = this;
    let id = _this.data.id;
    return {
      title: 'xxx',
      path: 'pages/index/index?id=' + id,
      imageUrl: "../../img/share.png"
