ng-zorro中nz-upload处于*ngFor循环中，请问如何在上传文件是获取ngFor的循环变量

Question

代码如下，我上传的文件需要同时伴随一个参数Item.id，请问有什么好的办法吗？

      <div *ngFor="let item of itemlist">
        <nz-upload [nzAccept]="'.*'"
                   [nzMultiple]="false"
                   [nzAction]="getSchemeUploadUrl()"
                   [nzHeaders]="getUploadHeader"
                   [nzFileList]="schemeFileTmpList"
                   [nzBeforeUpload]="beforeUpload"
                   (nzChange)="handleSchemeFileChange($event)"
                   class="scheme-upload-region">
                        <button tn-button [tnType]="'primary'" style="margin-right: 10px">上传文件</button>

        </nz-upload>
      </div>

Answer 1

<button tn-button [tnType]="'primary'" style="margin-right: 10px" (click)="save(item)">上传文件</button>
