新项目挖新坑，公司又需要做新的小程序，没有其他人支持，这次还得前后台一起做...不懂前端的我又来挖坑了...
先做小程序“我的”页面，需要注意的有两个点：
- 考虑到前几个版本getUserInfo不再弹出授权窗口，所以增加了不可见的button来唤起授权窗口；
- "我的"页面功能列表虽然现在不多，但是指不定什么时候就要增加或者修改，所以将该列表做成可配置的，使用了wx:for和navigator。
先上图，有图才有真相：
微信小程序--“我的“页面.jpg
一、 用户信息获取
这一块我增加了一个隐藏的button, 未获取到用户信息时，显示为默认头像和“微信授权”的文字提示，登陆后，头像变为微信头像，文字变为微信昵称。

具体ui为判断没有授权则显示默认头像及提示，并在其上层覆盖一个透明的button，用户触发授权事件。

js：
在js中需要注意的是，open-type="getUserInfo"需要做老版本兼容，老版本通过wx.getUserInfo即可唤起授权页面，不需要添加button去触发
