REST API - HTTP HEAD Method

The HTTP HEAD method lets you submit a request and receive a response with the response body omitted. The purpose of the HEAD method is to save bandwidth if you do not require the response data that is usually included in the body.

Example

If you want to determine the size of an attachment prior to downloading the file, you can use the HTTP HEAD method to submit your Get Attachment request. This allows you to determine the size of the attachment without having to download the file content.
Example

If you want to determine (approximately) how many artifacts exist for a particular filter, you can use the HTTP HEAD method to submit your List Artifacts request. This allows you to determine the size of the response without having to download the response body.

Python Example

def get_attachment():
        # obtain a token from our get_token() function
        token = get_token()

        # Of course, this ID would generally come from somewhere else instead of hardcoding it.
        project_id = "220870"
        artifact_id = "220914"
        attachment_id = "3194"

        # build the resource uri for listing artifacts in a given project
        resource_uri = 'https://production.blueprintcloud.com/api/v1/projects/' + project_id + '/artifacts/' + artifact_id + '/attachments/' + attachment_id

        # specify header parameters
        request_header={
                'Authorization' : 'BlueprintToken ' + token,
                'Accept' : 'application/xml'
        }

        # specify the uri parameters
        uri_parameters_list={
        }
	
        # create the request uri with the uri parameters
        request_uri = resource_uri + '?' + urllib.parse.urlencode(uri_parameters_list)
        output_requesturi(request_uri)
	
        response = requests.head(request_uri, headers=request_header)
        return response.headers
