ElementUI的Upload组件上传时如何携带参数

后端接口
    @PostMapping("/manual/import")
    @ApiOperation("手工导入")
    public RtnResult manualImport(@RequestParam("enterpriseGroupName") String enterpriseGroupName,
                                  @RequestParam("file") MultipartFile file,
                                  @RequestParam("enterpriseGroupDes") String enterpriseGroupDes) {
        return enterpriseGroupService.manualImport(enterpriseGroupName, file, enterpriseGroupDes);
    }

前端
    <el-upload
       class="upload-demo"
       :action="url"
       accept=".csv,.xlsx,.txt"
       show-file-list
       ref="uploadRef"
       :limit="2"
       :auto-upload="false"
       :multiple="false"
       :on-change="handleChange"
       :data={enterpriseGroupName:this.step1Form.groupName,enterpriseGroupDes:this.step1Form.groupComment}
    >
    使用 :data={参数} ,参数为键值对的形式{key1:value1,key2:value2},传递参数

    data() {
      return {
         step1Form: {
            groupName: '',
            nameList: '',
            groupComment: '',
         },
         url: this.$GLOBAL.teis + 'enterprise/group/manual/import'
      }
    }

    触发上传时，代码中加上this.$refs.uploadRef.submit();即可，例如下图

成功携带参数上传
