To use the example in this blog, you'll need

A SharePoint 2013 development environment (app isolation required for On-Premises scenario).

Visual Studio 2012 or Visual Studio 2013 with Office Developer Tools for Visual Studio 2012, or Napa (SharePoint Online only).

You'll also need to set full control add-in permissions at the Web scope. Only the users who have sufficient permissions to change the list permissions (such as site owners) can run this add-in.
  1. <script>
  2. var siteUrl = 'http://gowthamr.SharePoint.com';
  3. var listTitle = 'Tutorial List';
  4. var itemid='5';
  5. $(document).ready( function() {
  6. getattachmentfiles();
  7. });
  10. function getattachmentfiles() {
  11. $.ajax({
  12. url: siteUrl+"/_api/web/lists/GetByTitle("+listTitle+")/items(itemid)/AttachmentFiles('file name')/"
  13. method: GET,
  14. headers:{
  15. Authorization: "Bearer " + accessToken
  16. accept: "application/json;odata=verbose",
  17. content-type: "application/json;odata=verbose"
  18. content-length:length of post body},
  19. success: successHandler(responseData),
  20. error: errorHandler
  21. });
  22. }
  23. function successHandler(responseData) {
  24. var attachments=responseData.d.results;
  25. alert('Request updated Successfully.');
  26. }
  28. function errorHandler(xhr, ajaxOptions, thrownError) {
  29. alert('Request failed: ' + xhr.status + '\n' + thrownError + '\n' + xhr.responseText);
  30. }
  31. </script>
