Upload Microsoft PowerPoint Presentation to cloud storage with cURL command using Aspose.Slides REST API

I got an error when I tried to upload to storage. I need to know how to deal with it.
“Uploading a file from Cloud Storage”: /slides/storage/file/{path}

  • Uploading from local to storage

  • The “–binary” option in “cURL Example” was changed to “–data-binary” because the following error occurred.
    curl: option --binary: is unknown

  • The version of curl is as follows.
    curl --version
    curl 7.55.1 (Windows) libcurl/7.55.1 WinSSL

We are truly sorry for the inconvenience. Unfortunately there is typo error in the documentation. UploadFile method is PUT method instead of POST. We will fix the documentation asap. Please use following cURL command for uploading file to the cloud storage.

curl  -v -X PUT "" 
-H "Content-Type:application/octet-stream" 
-H "authorization: Bearer [Access_Token]" 
--data-binary @C:/Temp/AccessSlides.pptx

I was able to run it successfully with the above command. Thank you very much.
