Rest Api - Retrieve file

Posted by matman on 03-Nov-2014 10:22

I am using getBinaryData to retrieve a .jpg file from my application. When I access this command via my browser, using manual login etc. I receive an error stating that the image is corrupted. I figured the content could be compressed, but gzip and deflate decompression didn't work for me either. I was unable to decode it as base64 string as well. So how could I achieve this? :/

Are you using REST API?

Posted by matman on 03-Nov-2014 10:26

Yes, I am using the Rest Api and the public Rollbase hosted by Progress

REST API getBinaryData will send back actual binary data (from previously uploaded file) with valid content type. I just tested this API, sample URL:

http://localhost:8080/rest/api/getBinaryData?objName=hierarchy&id=491765&fieldName=my_file&sessionId=ef111e4d0c5b4de183a4bd5cf541622f@5903

I have been trying, but I really can't seem to open the image. The image is viewable from Rollbase itself, but not via the browser when I manually input the API URL nor is it via Fiddler.

Are you using File Upload or Image field?

Please also provide URL you're using

Hi matman,

I was able to render both file and image upload on Firefox. The test was also done on the hosted cloud using the link below:

www.rollbase.com/.../getBinaryData

I got this result from Fiddler:

I added a new file upload field and was able to successfully retrieve the image without an error. Apparently the file field I used to upload, uploads files encrypted. I cannot find any information about decrypting the file on my side or retrieving the file decrypted by the server, is there any way I could do so?


[mention:05b5f00eae4a468d844fa8bedcafd110:e9ed411860ed4f2ba0265705b8793d05] I used URL: http://rollbase.com/rest/api/getBinaryData?sessionId=857bfcdfc9824b6982b9b49636ed5572@108169344&id=113986842&objName=website3&fieldName=file . Field with integration name "file" is a file upload field. But I found out I told it to encrypt all uploaded files a long time ago.

So are you saying that REST API does not decrypt encrypted file? Just to make sure. Files should definitely be decrypted before being retrieved by API.

Yes indeed. I was able to retrieve the image from the upload field, but when I checked encrypt and reuploaded the same image, I got the corrupted image error again.
