  • @Anshu Prateek i already see that and try but still no luck. Maybe it needs some openstack server configuration, but we have no idea. – darrel May 27 '15 at 10:00

Maybe you are trying to reach a container that you did not append the origin of the page to the container’s X-Container-Meta-Access-Control-Allow-Origin header. You can append it to your container using something like this curl:

curl -X POST -H 'X-Auth-Token: xxx' \
  -H 'X-Container-Meta-Access-Control-Allow-Origin: http://localhost' \
  http://192.168.56.3:8080/v1/AUTH_test/cont1

Here is the full description on this subject on Openstack documentation: http://docs.openstack.org/developer/swift/cors.html

For anyone that went to the official docs and then was stuck with the paramentes for the cURL post.

This are two ways of doing this.

Using python-openstackclient

Use pip install python-openstackclient to get the package and use the ENV vars to authenticate.

Once you can issue a command like openstack container show your-container, then you can also use set --property.

E.g

openstack container set --property Access-Control-Allow-Headers='Content-Type, X-CSRFToken' your-container
openstack container set --property Access-Control-Allow-Origin='https://your.domain.com https://other.domain.com' your-container

Using cURL

In order to user curl, you want to post a command like:

curl -i -X POST -H 'X-Auth-Token: <YOUR_TOKEN>' \
  -H 'X-Container-Meta-Access-Control-Allow-Origin: https://your.domain.com ' \
  <YOUR_STORAGE_URL/your-container>

For this you need to find YOUR_TOKEN and YOUR_STORAGE_URL.

You can use the python-swiftclient (pip install python-swiftclient). After authenticating, run

swift stat -v --info

The output will contain both:

                 StorageURL: YOUR_STORAGE_URL
                 Auth Token: YOUR_TOKEN
                    Account: v1
                 Containers: 99
                    Objects: 9999
                      Bytes: 999999
  Strict-Transport-Security: max-age=31536000; includeSubdomains
                     Server: nginx
                 Connection: keep-alive
                X-Timestamp: 1505478377.08455
X-Account-Bytes-Used-Actual: 9999999
                 X-Trans-Id: tx009999999999a9-999999-9999999-default
               Content-Type: text/plain; charset=utf-8
              Accept-Ranges: bytes
