data 建立对象

fileList : [], // 这是为了方便上传之后清空数据展示

　　methods 方法

  //上传成功的样子
        handleAvatarSuccess(res, file) {
        
            if(res.code == '500') {
                this.$message.error(res.msg)
                this.fileList = []
                return
            }
            this.fileList = []

           
            this.$message.success("导入成功")
            
        },

        beforeAvatarUpload(file){
            
            var testmsg = file.name.substring(file.name.lastIndexOf('.')+1)
            
            const xls = testmsg === 'xls'
            const xlsx = testmsg === 'xlsx'
            
            if(!xls && !xlsx ){
                this.$message.error("请选择xls/xlsx 格式的文件")
                return false
            }
