REST API to get content of a specific version of a file

anant

Hi,

Is there any REST API which returns the content of a specific version of a file? I am using /alfresco/service/api/node/content/workspace/SpacesStore/<id> API to get the content of the latest version, but didnt find any API which returns content for only a specific version which might not be latest.

For example if a file has 2 version 1.0 and 1.1, i want to get the content of 1.0 version file.

Thanks in advance.

You can check if https://community.alfresco.com/community/ecm/blog/2016/11/11/v1-rest-api-part-5-versioning-locking is what you need.

Please note that this ReST API is currently only supported against an Alfresco 5.2 EA installation. A GA release of Alfresco 5.2 may occur this month.

If you want to access an older version of Alfresco you should check the URL index for internal ReST APIs via /alfresco/service/index for an appropriate operation.

Thanks Kayne for your reply.

Tried with the APIs mentioned in the post, but didnt work. Not sure if they are available for the version that i am using, i.e 5.0d community version.

Got the below output:

REST URL: http://localhost:8080/alfresco/api/-default-/public/alfresco/versions/1/nodes/c9bc6b23-8673-47ec-b3a3-2f0040f17f58/versi…

OR: http://localhost:8080/alfresco/api/-default-/public/alfresco/versions/1/nodes/workspace/SpacesStore/c9bc6b23-8673-47ec-b…

Output (removed stack trace):

{
"error": {
"errorKey": "Unable to locate resource resource for :nodes versions",
"statusCode": 400,
"briefSummary": "11130009 Unable to locate resource resource for :nodes versions",
"descriptionURL": "http://developer.alfresco.com/ErrorsExplained.html#Unable to locate resource resource for :nodes versions"
}
}

Am i doing something wrong?

I tried some service API URLs by appending version information to them, but it seems they always return the latest version irrespective of the version that is mentioned in the request

I'm sorry ,as Axel Faust said your version 5.0d might not support this restful api,.

Can you try to use apache chemistry opencmis library or customize your own webscript api.
