Trying to use get_attachment_content in RESTful API

[jeffpohlmeyer]

I have a site for which I'm building a customer comment/feedback section that I am hooking into DevOps to almost use as a SaaS so that we don't have to manually add bugs to DevOps. I've built functionality where a user can upload a file, but I want to build functionality to allow the user to again view the file that s/he uploaded. When I try to invoke get_attachment_content for a given ID I get a type <generator object RequestsClientResponse.stream_download at ...> How am I able to grab the content from said generator in order to convert it to a file to send for download? Even if I'm able to get the binary data from the generator it would be helpful because I can then convert the binary myself.

Here is an example of doing a file download. In this example we download all attachments found on work items from the given wiql query:

def download_callback(chunk, response):
    pprint.pprint('Downloaded chunk of size: ' + str(len(chunk)))


wit_client = connection.clients.get_work_item_tracking_client()

wiql = Wiql()
wiql.query = "Select [System.Id], [System.Title], [System.State] From WorkItems Where [System.WorkItemType] = 'Task'"

wiql_results = wit_client.query_by_wiql(wiql, top=100).work_items
if wiql_results:
    pprint.pprint(wiql_results)
    work_items = (
        wit_client.get_work_item(int(res.id), expand='Relations') for res in wiql_results
    )
    for work_item in work_items:
        pprint.pprint(work_item)
        if work_item.relations is not None:
            for relation in work_item.relations:
                if relation.rel == 'AttachedFile':
                    response = wit_client.get_attachment_zip(relation.url.split('/')[-1],
                                                             download=True,
                                                             callback=download_callback)
                    with open(relation.attributes['name'], 'wb') as f:
                        for x in response:
                            f.write(x)
