Upload files greater than 2MB on Private Cloud - HTTP Reques

Posted by IramK on 02-Dec-2014 11:19

Hello,

I have carried out uploading files onto Rollbase (Trial account and Private Cloud) with files less than 2MB. I am trying to upload files greater than 2MB over private cloud using the code given here: https://community.progress.com/community_groups/rollbase/f/25/t/14028.aspx?pi20882=2#50394. Since HTTP request body uses multipart form data to process larger files, I am trying to build the request body to send the POST data. When trying to do that, I am getting an error: "Corrupt form data: premature ending" Could you guys let me know on where I am going wrong?

POST http://privatecloud.com/rest/api/setDataField HTTP/1.1
User-Agent: Mozilla/5.0 (Windows NT 6.3; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/39.0.2171.71 Safari/537.36

Managed to solve it by change the POST HTTP request body to the following given below:

POST http://privatecloud.com/rest/api/setDataField HTTP/1.1

This may be Apache configuration issue.

Hi Iram,

Have you tried increasing the file size limit of the field to be updated? If yes, can you please confirm whether or not you are still using the same code used on the previous thread?

Thanks,
Godfrey

Yes I have tried increasing the file size limit of the file to be updated on both Rollbase and the server configuration but I still get the same error. I am using the same code that I used on the previous thread and it works for files less than or equal to 1.3 MB but doesn't work beyond that.
