1. 去iconfont下载字体图标素材 （网址：https://www.iconfont.cn/）

2. 打开下载内容的 iconfont.css文件

@font-face {font-family: "iconfont";
  src: url('iconfont.eot?t=1592818034287'); /* IE9 */
  src: url('iconfont.eot?t=1592818034287#iefix') format('embedded-opentype'), /* IE6-IE8 */

}

.iconfont {
  font-family: "iconfont" !important;
  font-size: 16px;
  font-style: normal;
  -webkit-font-smoothing: antialiased;
  -moz-osx-font-smoothing: grayscale;
}

.icon-wode-copy-copy:before {
  content: "\e600";
}

.icon-shouye:before {
  content: "\e613";
}

3. 引入uni-app

将iconfont.css 复制到 App.vue 中的style中

3.1 base64方式引入uni-app

删掉@font-face中的非base64内容，就是下图中红线标记的内容

修改后的内容为：

@font-face {
		font-family: "iconfont";
		src: url('data:application/x-font-woff2;charset=utf-8;base64,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') format('woff2');
	}	
.iconfont {
	font-family: "iconfont" !important;
	font-size: 32px; /* 调整字体图标大小 */
	font-style: normal;
	-webkit-font-smoothing: antialiased;

}

.icon-wode-copy-copy:before {
	content: "\e600";
}

.icon-shouye:before {
	content: "\e613";
}

3.2 https方式，引用阿里cdn图标地址

先删除@font-face中所有内容，然后打开iconfont中的该项目，如下图

点击查看在线连接 ， 然后点击生成（如果有就略过该步骤）

复制代码 ，替换掉 App.vue中的@font-face，然后将@font-face中的 //at 全部替换成 https: //at。
修改后的内容为：
