前端

//获取文件信息
handleChange(file,fileList){
      this.fileInfoList = fileList;
      console.log(this.fileInfoList)
    },
    
    
submitForm:function (){
this.fileInfoList.forEach((val,index) => {
          formData.append("file",val.raw)
        });
          this.form.fileName = packetName
          uploadVersion(formData).then(response =>{
        console.log(response)
        }
}
