el-upload上传文件401原因及解决办法

el-upload上传文件401可能是请求头没有设置token导致，在element-ui文档中有headers属性，

 在headers属性中添加token即可

html：
<el-upload
  ref="upload"
  :showUploadList="false"
  :on-success="handleSuccessImport"
  :on-error="uploadhandleError"
  accept="xls,xlsx,docx"
  :headers="ausorToken"  // hesaders属性
  :on-progress="handleProgress"
  action="http://localhost:8081/citec/newImportbak/import/"
  class="uploadClass"
  >批量导入账号</el-upload
>

js：
data(){
    return{
         Authorization:""
    }
}

created(){
    this.ausorToken.Authorization = 'Bearer ' + getToken() //getToken()获取token的api
}
