How to get a blob image with cURL?
Hello.
We are Nuxeo ECM total rookies. We have defined a document model in our ECM instance, and this model contains a blob “illustration” attribute, which enables to store an image.
When looking at the rendering page which of that document model, when the blob attribute has been fulfilled with a picture, the image is diplayed in ECM with an hyperlink like “http://localhost:8080/nuxeo/nxfile/default/351993be-1ee6-43c1-b081-709a519f665c/as:illustration/image.png”.
We strive to download that image from the command line with cURL with the command 'curl -H 'Content-Type:application/json+nxrequest' -u:Administrator:Administrator “http://localhost:8080/nuxeo/nxfile/default/351993be-1ee6-43c1-b081-709a519f665c/as:illustration/image.png”', authenticated properly, but this command returns an empty stream. Eventually, we will achieve that download from a Java application, which cannot use the Automation client, because we run in a Google App Engine box.
However, we thought that we had followed the documentation available at “http://doc.nuxeo.com/display/NXDOC55/Using+cURL”, but we must have missed something. I need to mention that, if we open a browser with the URL “http://localhost:8080/nuxeo/nxfile/default/351993be-1ee6-43c1-b081-709a519f665c/as:illustration/image.png”, the browser proposes to open or save the file.
If someone could help us to work this out, we would be grateful. Thank you for your attention.
Regards, Édouard

This is most probably because you have a syntax error in your command:
curl -H 'Content-Type:application/json+nxrequest' -u:Administrator:Administrator “http://localhost:8080/nuxeo/nxfile/default/351993be-1ee6-43c1-b081-709a519f665c/as:illustration/image.png”
Please note there should be a space instead of the colon between -u and Administrator to have the following instead:
-u Administrator:Administrator

Just an after thought, running
curl -I -H 'Content-Type:application/json+nxrequest' "http://localhost:8080/nuxeo/nxfile/default/351993be-1ee6-43c1-b081-709a519f665c/as:illustration/image.png"
actually returns the right HTTP status,
HTTP/1.1 302 D?plac? Temporairement
Server: Apache-Coyote/1.1

which accounts for the credential issue ;) Maybe, a “forbidden” status would be better…
