how to to get access to command runner payload

[OaklandCounty_Mike]

Good morning.

i have been trying to utilize the command runner api with the dnacentersdk.  

i been following the tutorial here: https://blogs.cisco.com/developer/network-automation-cisco-dna-center-sdk-2

but the file does to download anywhere to my system, and i am not sure where to access it in DNA center.  

here is the code i am using:

import json

from rich.console import Console

from dnacentersdk import DNACenterAPI

from dnacentersdk.exceptions import ApiError

dnac = DNACenterAPI(username= DNAC_USER, password= DNAC_PASS, base_url= DNAC_URL, verify=False)

myConsole = Console()

def cmd_run(device_list

    for device in device_list:

        print("Executing Command on {}".format(device))

        run_cmd = dnac.command_runner.run_read_only_commands_on_devices(commands=["show run"], deviceUuids=[device])

        print("Task started! Task ID is {}".format(run_cmd.response.taskId))

        task_info = dnac.task.get_task_by_id(run_cmd.response.taskId)

        task_progress = task_info.response.progress

        print("Task Status : {}".format(task_progress))

        while task_progress == 'CLI Runner request creation':

            task_progress = dnac.task.get_task_by_id(run_cmd.response.taskId).response.progress

        task_progress= json.loads(task_progress)

        cmd_output = dnac.file.download_a_file_by_fileid(task_progress['fileId'], dirpath='C:/Users/bussardm/OneDrive - Oakland County/Documents/Python scripts/file.json')

        myConsole.print(cmd_output)

        print("Saving config for device ... \n")

devices = dnac.devices.get_device_list(management_ip_address='10.255.47.1')

devicesuid_list = []

for device in devices.response:

    if device.family == 'Switches and Hubs':

        devicesuid_list.append(device.id)

        print("Device ID: {} ".format(device.id))

    print("Device Management IP: {} ".format(device.managementIpAddress))

    cmd_run(devicesuid_list)

Hi @OaklandCounty_Mike,

 For me, to get it to download, I had to also use the save_file parameter and not specify a filename in the dirpath, like so:

cmd_output = dnac.file.download_a_file_by_fileid(task_progress['fileId'], save_file=True, dirpath="/Users/alexstev/Desktop/temp/")

When I ran the above code I can see the files created in the local folder

Here's how the docs explain those parameters:

download_a_file_by_fileid(file_id, dirpath=None, save_file=None, filename=None, headers=None, **request_parameters)[source]¶
Downloads a file specified by fileId.

Parameters
file_id (basestring) – File Identification number.
dirpath (basestring) – Directory absolute path. Defaults to os.getcwd().
save_file (bool) – Enable or disable automatic file creation of raw response.
filename (basestring) – The filename used to save the download file.
headers (dict) – Dictionary of HTTP Headers to send with the Request .
**request_parameters – Additional request parameters (provides support for parameters that may be added in the future).

I'm not sure how (or even if) we can access that local file in the DNA Center GUI. You can try out the command runner in the GUI here: https://sandboxdnac.cisco.com/dna/tools/command-runner

You can also use the DevNet sandboxes for this. Currently, we have two DNA Center sandboxes. That's what I used.
