角度代码(素数吴(

<p-fileUpload mode="basic" name="demo[]" url="https://gateway.xxx.intra/file"  maxFileSize="1000000" (onUpload)="onBasicUpload($event)" auto="true">

来自服务器的响应

邮递员标题

curl -X POST 
  https://gateway.xxx.intra/file 
  -H 'Postman-Token: xxxx3d14-dfee-4c6b-85e1-5592c2e0f9e2' 
  -H 'cache-control: no-cache' 
  -H 'content-type: multipart/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW' 
  -F 'send_files[]=@C:UsersxxxDocumentsimport_template.xlsx'

浏览器请求标头是

Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet

当您向服务器发出请求并将响应解析为 JSON 时，会发生这种情况，但它不是 JSON。
