当我们基本信息没有填完之前,是不能进行页签切换的,所以需要采用以下的方式进行阻止:

beforeTabLeave(activeName,oldActiveName){
if(oldActiveName == '0' && this.addForm.goods_cat.length != 3){

if(res.meta.status !== 200) return this.$message.error('获取父级分类列表失败')
// 将attr_vals进行分割 获得标签

res.data.forEach(item => {

})
console.log(res.data)
this.manyTableData = res.data
}
}

由于Element-UI中的upload组件并没有调用axios,于是需要主动指定请求头中Authorization字段。
