说明
本模块首批接口从API version 6开始支持。后续版本的新增接口，采用上角标单独标记接口的起始版本。

一.创建项目
二.示例代码
index.hml

<div class="container">
    <div class="img">
        <text>获取头像</text>
    </div>
    <text class="title">
        <span>是否进行用户认证</span>
    </text>
    <div class="btn">
        <button value="取消认证" onclick="cancelAuth"></button>
        <button value="确定认证" onclick="startAuth"></button>
    </div>
