修改\leam-ui\src\views\modules\sys\config\SysConfig.vue

1. <el-form-item label="产品logo">
   
2.             <el-upload
   
3.               class="avatar-uploader"
   
4.               :action="`${$http.BASE_URL}/sys/file/webupload/upload?uploadPath=logo`"
   
5.               :on-success="handleAvatarSuccess"
   
6.               :before-upload="beforeAvatarUpload"
   
7.                :show-file-list="false">
   
8.               <img v-if="themeFormSetting.logo" :src="themeFormSetting.logo" class="avatar">
   
9.               <i v-else class="el-icon-plus avatar-uploader-icon"></i>
