Issue in remote Windows upload.

[sankamuk]

I have used the upload code to transfer file from my local Linux host to a remote Windows using the below code.

def run_to_copy(server_name, local_path, remote_path) :
"""
Usage:
"""
host_name = "http://"+ server_name +":5985/wsman"
win_connect = Protocol(endpoint=host_name, transport='kerberos')
shell_id = win_connect.open_shell()
step = 1024
timeout = 3600
size = os.stat(local_path).st_size
start = time.time()
with open(local_path, 'rb') as f:
for i in range(0, size, step):
script = (
'add-content -value '
'$([System.Convert]::FromBase64String("{}")) '
'-encoding byte -path {}'.format(
base64.b64encode(f.read(step)),
remote_path
)
)
while True:
encoded_ps = base64.b64encode(script.encode('utf_16_le')).decode('ascii')
command_id = win_connect.run_command(shell_id, 'powershell -encodedcommand {0}'.format(encoded_ps))
code, stdout, stderr = win_connect.get_command_output(shell_id, command_id)
if time.time() - start >= timeout:
raise Exception('WinRM upload file transfer timedout '+ str(timeout) +".")
if code == 0:
break
elif code == 1 and 'used by another process' in stderr:
time.sleep(0.1)
else:
print(stderr)
print(stdout.decode('utf-8'))
raise Exception('Failure: in transfer.')

When i execute the same i get the following encoding exception when transferring a simple ASCII file:
