开发微信小程序的源码怎么写

微信小程序的canvas不能画gif 也不能把画布到出成gif 但是jp png是可行的，这是一个bug吗

https://developers.weixin.qq.com/miniprogram/dev/framework/user-privacy/PrivacyAuthorize.html [图片] 小程序后台已经配置摄像头、本地图片选择等隐私设置并审核通过

有一个image，代码里是有bindtap的，如下： <image src="/static/images/platupload.png"  bindtap="chooseImg"></image> 上传到体验版测试之后 ，变为了,是什么原因： <image src="/static/images/platupload.png"  role="img"></image>

搞什么啊

微信监听wx.onNeedPrivacyAuthorization(resolve => {}）时，resolve的值为空，有谁遇到过这个问题吗
