*
* @property {String} src 头像路径如加载失败将会显示默认头像(不能为相对路径)
* @property {String} shape 头像形状 circle (默认) | square
* @property {String | Number} size 头像尺寸可以为指定字符串(large, default, mini)或者数值 默认 40
* @property {String} mode 头像图片的裁剪类型与uni的image组件的mode参数一致如效果达不到需求可尝试传widthFix值 默认 'scaleToFill'
* @property {String} text 用文字替代图片级别优先于src
* @property {String} bgColor 背景颜色一般显示文字时用 默认 '#c0c4cc'
* @property {String} color 文字颜色 默认 '#ffffff'

* @property {String} icon 显示的图标
* @property {Boolean} mpAvatar 显示小程序头像只对百度微信QQ小程序有效 默认 false
* @property {Boolean} randomBgColor 是否使用随机背景色 默认 false
* @property {String} defaultUrl 加载失败的默认头像(组件有内置默认图片)
* @property {String | Number} colorIndex 如果配置了randomBgColor为true且配置了此值则从默认的背景色数组中取出对应索引的颜色值取值0-19之间
* @property {String} name 组件标识符 默认 'level'
* @property {Object} customStyle 定义需要用到的外部样式
*
* @event {Function} click 点击组件时触发 index: 用户传递的标识符
