Iron-ajax下载文件

Question

I want to using download a file using Polymer's Iron-Ajax.

<iron-ajax
  id="fileDownloader"
  headers='{"Auth" :"token"}'
  url="/my/server/rest/download/csv/{{id}}"
  method="GET"
  content-type="application/json"
  on-response="downloadCsvCallLoaded"
  on-error="downloadCsvCallFailed">
</iron-ajax>

The reposnse actually contains the data, but it does not trigger the browser to download the file.

I think you need to use handle-as="blob"property in your element declaration. Here you can find more information about it.
