处理字体ttf的loader

步骤:
1.安装包cnpm i file-loader url-loader -D
2.在webpack.config.js的module.exports的moudle的rules添加匹配规则

{test:/\.(eot|woff2|woff|ttf|svg)/,
   use:[
       {loader:'url-loader',
           options:{
               name:'[name][hash:5].min.[ext]',
               limit:5000,
               publicPath:'',
               outputPath:'dist/',
               useRelativePath:true
           }
       }
   ]
}
