Downloading files from Livelink URL

[pratikr]

I have an excel spreadsheet with one of the columns containing Livelink URLs in the following format - http://livelink.organisation-name.net/livelink.exe/open/{file_id} where file_id is the placeholder for actual file identifiers. I have to automate the task of downloading the files and placing them in appropriate folder based on certain tag (not relevant). I am trying to write a Python script to automate and using requests.get method but having trouble with authentication. I have two questions -

1. What authentication patterns can be used to achieve this objective?
2. Can I pass the above URL in requests.get method to retrieve the underlying PDF file?

1. Using OTDS or OTCS authentication endpoint get a token.A valid tokeen is needed for any operation.
2. REST API has a method to fetch the content.You will have to create a file object to receive the content.
3. Since your operation involves multiple downloads you should create a chained mechanism for example when you download your first file in the headers livelink will return you a token use this for next and next so that they do not time out.

Correct me if I am wrong - In order to fetch the file from the appropriate API method will I have to extract the node id from the URL mentioned above?
Also, is there any way I can use urllib.request.urlretrieve to directly use the given URL?

Yes CS after authentication needs to be told the VERB with which a NODEID has to be accessed as in Download,Version etc...
REST API is no different from an actual CS URL
- http://livelink.organisation-name.net/livelink.exe/open/{file_id} when you issue the call after authentication the livelink request handler will see the nodeid and do what Open is coded to do for that NodeID

I don't fully know what this is urllib.request.urlretrieve what is the context or language this is about looks like it is a python library.Several programmers in OT KB has put python snippets to get livelink content.I have not done python so I cant comment.
