Mark Jenkins node temporarily disabled using JENKSES REST API

we have a Jenkins Matrix job that tests several variants of our software in parallel on many slave nodes. It sometimes happens that one of these alarms obeys and needs to be reloaded. I don't want to miss the run in this case. I don't want to mark a particular slave node as temporarily unavailable by an underloaded script that detects a failure and then reloads the node. I found out that this should be possible with the JENKSES REST API. And I found two python libraries that should do the job; https://python-jenkins.readthedocs.org/en/latest/index.html and http://pythonhosted.org/jenkinsapi/index.html... But both libraries have problems to change something in my Jenkins 1.580.2 system (getting information is not a problem) with python 3.4.3.

JenkinsAPI:

from jenkinsapi.jenkins import Jenkins
from jenkinsapi.utils.requester import Requester

class SSLRequester(Requester):
    def __init__(self, username=None, password=None):
        super(SSLRequester, self).__init__(username, password)

   def get_request_dict(self, *largs, **kwargs):
        requestKWargs = super(SSLRequester, self).get_request_dict(*largs, **kwargs)
        requestKWargs['verify'] = False
        return requestKWargs 

jenkins = Jenkins(jenkinsurl, username, password, requester=SSLRequester())

      

        
        
        
      

    

I need to use the SSLRequester setup because I am using an https: // connection for my Jenkins server and I am getting the following error:

SSLError: SSL certificate confirmation: CERTIFICATE_VERIFY_FAILED] (_ssl.c: 600)

Ok if I try to get some information using jenkins object everything is fine.

node.is_temporarily_offline()
False

      

        
        
        
      

    

But if I try to switch node I get this:

node.toggle_temporarily_offline()

      

        
        
        
      

    

JenkinsAPIException: The operation failed. url = https: /// computer // toggleOffline? offlineMessage = requested% 20from% 20jenkinsapi, data = {}, headers = {'Content-Type': 'application / x-www-form-urlencoded'}, status = 403, text = b "% 2FtoggleOffline% 3FofflineMessage% 3Drequested% 2520from% 2520jenkinsapi '/ "> window.location.replace (' / login?

My login details are completely ignored.

Python-Jenkins:

import jenkins
j = jenkins.Jenkins(jenkinsurl, username, password)
j.disable_node(slavenode)

      

        
        
        
      

    

TypeError: JSON object must be str, not 'bytes'

After doing a little googling, I found out that I need to fix the library because JSON doesn't like the bytearrays that Jenkins provides the JSON API. After inserting several decrypted ('utf-8') statements, I was able to call the following statement:

j.get_node_info(slavenode)

      

        
        
        
      

    

But I still can't mark it as offline:

j.disable_node(slavenode)

      

        
        
        
      

    

TypeError: POST data must be bytes or iterable bytes. It cannot be of type str.

So translate this into a simple question. Do you know of any other handy, scripted way to mark a node as temporarily offline (and of course online again if the reboot is successful)? I would prefer a python solution because I am starting a reload from my python script. But the groovy script will be good enough too.

Thanks in advance for your help
