1. 首先打开阿里字库，搜索图标添加到项目
2.每次添加以后要生成新的css链接
3. 前端通过上面的链接可以查看到对应图标名的unicode代码进行复制
4. 配置一下即可使用在线图标（这里是App.vue导入）
@font-face {
font-family: \'iconfont\';
/* project id 1657156 */
src: url(\'//at.alicdn.com/t/font_1657156_6equm9708jx.ttf\') format(\'truetype\');
}
.iconfont {
font-family: "iconfont" !important;
font-size: 16px;
font-style: normal;
-webkit-font-smoothing: antialiased;
-moz-osx-font-smoothing: grayscale;
}
.icon-zan:before {
content: "\e682";
}
.icon-close-b:before {
content: "\e632";
}
.icon-shangchuanwenjian:before {
content: "\e613";
}
5. 在页面中使用
6.建议项目完成后还是导入本地图标

7. uniapp支持多端或者说有差异性（有的只支持在线字体图标，有的只支持本地字体图标），那就这样
@font-face {

8. 字体图标不支持多色彩，可以使用svg替换png(svg矢量图等比例缩放，png位图等比例缩放会出现锯齿等情况)
好了，尽情使用吧！
