微信小程序头像昵称填写能力-数据存储至缓存

又到了一年一度的授权接口修改时间---ps.去年10月，希望今年能消停点。

话不多说上代码。

<button class="avatar-wrapper" open-type="chooseAvatar" bind:chooseavatar="onChooseAvatar">
  <image class="avatar" src="{{avatarUrl}}"></image>
</button>
<view class="form-box">
  <form catchsubmit="formSubmit">
      <view class="row">
        <view class="text1">昵称：</view>
        <input type="nickname" bindinput="getName" class="weui-input" maxlength="16" minlength="2" name="input" placeholder="请输入2~16位昵称" value="{{nickName}}" />
      </view>
      <button class="sub-btn"  formType="submit">提交</button>
  </form>
</view>
