title: NG-ZORRO NzUpload How use NzDownload function
body: <pre><code>&lt;nz-upload
            class=&quot;file-uploader&quot;
            [nzCustomRequest]=&quot;customReq&quot;
            [(nzFileList)]=&quot;fileList&quot;
            [nzDownload]=&quot;downloadReq&quot;
            [nzBeforeUpload]=&quot;beforeUpload&quot;
            (nzChange)=&quot;handleChange($event)&quot;
    &gt;
      &lt;button tc-button [beforeIcon]=&quot;'icofont-upload-alt'&quot; [type]=&quot;'button'&quot;&gt;Click to upload&lt;/button&gt;
    &lt;/nz-upload&gt;
  </code></pre>
  <p>Typescript</p>
  <pre><code>downloadReq = (file: NzUploadFile) =&gt; {}
  </code></pre>
  <p>How use this method to request? File can be downloaded who has access. And I can't set header to download request. I use angular 9.</p>
