onShareAppMessage可以传几个参数？

onShareAppMessage: function() {

let that = this;

//分享页面路径

let shareUrl = "/pages/message/activitylist/detail/index?id=" + that.data.activityId;

return {

path: '/pages/message/activitylist/detail/index?shareUrl=' + shareUrl + "&id=" + that.data.activityId,

}

}

在onLoad里面获取的时候获取不到id值，并且shareUrl 参数里面拼接的ID值也没有
