微信小程序中使用自定义图标（阿里icon）的方法

weui提供的图标比较少，有时我们需要更多的图标，可以使用以下方法自定义图标库：

1，到阿里巴巴矢量图标库(http://iconfont.cn/)生成自己的字体图标，下载代码，解压，打开iconfont.css

2，在wxss文件中引用字体

<style type="less">

@font-face {
    font-family: 'iconfont';
    src: url(data:font/truetype;charset=utf-8;base64,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) format('truetype'),
