Description
Jose Antonio sent a message using the contact form at
http://catalogue.fiware.org/.
I am trying to use the temp url feature in Swift object storage. The use case
is being able to generate public urls for picture files so that they can be
shown in my application web page (using html img tag). I've managed to upload
and download files using curl and my auth token, following the instructions
in
http://forge.fiware.org/plugins/mediawiki/wiki/fiware/index.php/Object_Storage_-_User_and_Programmers_Guide.
In order to use temp url feature I've followed the guide in
http://docs.openstack.org/kilo/config-reference/content/object-storage-tempurl.html.
I've done the following:
I've generate the X-Account-Meta-Temp-URL-Key using the command swift
post -m "X-Account-Meta-Temp-URL-Key:b3968d0207b54ece87cccc06515a89d4".
I've verified that the temp url key has been successfully saved using
swift stat command.
I've generated the temp file url using the tool swift-temp-url. This
tool
gives an url with all the parameters needed (temp_url_sig and
temp_url_expires).
I've copied the url obtained in the previous step to my browser and
tried
to retrieved the file, obtaining a message telling that I am not authorized.
The same happens using curl.
What am I doing wrong? I really need to get this feature working in order to
be able to feed my application with pictures.
Thank you very much,
Jose

In addition, even if running Kilo release, the tempurl feature probably needs to be enabled by having it in the Swift proxy-server pipeline. Can we see the proxy-server conf file? What about the proxy logs?
Hi! Running the command swift capabilities I obtain version version:
2.5.1.dev134. From the information in this link
<https://github.com/openstack/swift/blob/master/CHANGELOG> It seems that
Liberty release included swift 2.5.0, so my version should support temp url
feature.
I am using Swift SAIO version, installed according to documentation in this
link <http://docs.openstack.org/developer/swift/development_saio.html>. The
proxy server pipeline is the following:
pipeline = catch_errors gatekeeper healthcheck proxy-logging cache bulk
tempurl ratelimit crossdomain container_sync tempauth staticweb
container-quotas account-quotas slo dlo versioned_writes proxy-logging
proxy-server
I am not using keystone, I am using tempauth, I do not know if that is ok
or not.
The sequence of requests I make are:
curl -v -H 'X-Auth-User:ubiprint3d:admin' -H 'X-Auth-Key:changeme'
http://localhost:8080/auth/v1.0/ --> I obtain X-Auth-Token:
AUTH_tke7ad8b3cbc184d8b9bccd34a5202f933
curl -v -H 'X-Auth-Token: AUTH_tke7ad8b3cbc184d8b9bccd34a5202f933'
http://localhost:8080/v1/AUTH_ubiprint3d --> I obtain (as expected)
X-Account-Meta-Temp-Url-Key: cafebabe
curl -H 'X-Auth-Token: AUTH_tke7ad8b3cbc184d8b9bccd34a5202f933'
http://localhost:8080/v1/AUTH_ubiprint3d/ubiprint3d --> returns one line:
image.jpg (the only one object in container)
swift-temp-url GET 86400 /v1/AUTH_ubiprint3d/ubiprint3d/image.jpg
b3968d0207b54ece87cccc06515a89d4 --> returns temp url
/v1/AUTH_ubiprint3d/ubiprint3d/image.jpg?temp_url_sig=2b66fc0c43f7155f8fb9d0eda28ac0d7e7679f78&temp_url_expires=1448082214
curl -X GET -v
http://localhost:8080/v1/AUTH_ubiprint3d/ubiprint3d/image.jpg?temp_url_sig=2b66fc0c43f7155f8fb9d0eda28ac0d7e7679f78&temp_url_expires=1448082214
--> returns 401 Unauthorized: Temp URL invalid
What am I doing wrong?

I've installed swift version 2.5.0 (the one included in liberty) and
repeated the process with same result: 401 Unauthorized: Temp URL invalid

Found the problem!! In the request
the HTTP path should be quoted, if not bash splits out all the url after
the character &
Silly mistake, I've lost hours solving this.
Thanks!

According to the documentation on http://docs.openstack.org/kilo/config-reference/content/object-storage-tempurl.html it seems that this feature was introduced in the Kilo release.
Are you sure that your Swift installation is running Kilo? In the Fiware labs, they are currently running Juno release. An update to Kilo release is planned for the near future for some of the regions.
