小游戏怎么设置分享呢？弹出菜单提示：当前页面未设置分享，api给的onShareAppMessage必须要有Page设置才行，代码看了下没有Page啊：
//这个调用也失败了：fail no permission, with arg withShareTicket: true
wx.showShareMenu({
withShareTicket: true,
fail: function (res) {
console.log(‘showShareMenu fail:’+res.errMsg)
},
success: function () {
console.log(‘showShareMenu success’)
}
})
