执行Jenkins.wipeout_job_workspace()时可能报此错误
3. 环境

python版本：

Python 3.7.0 (v3.7.0:1bf9cc5093, Jun 27 2018, 04:59:51) [MSC v.1914 64 bit (AMD64)] on win32

3. 原因和解决方案

在该模块的源文件site-packages\jenkins\__init__.py中，大约1426行，调用requests.Request时传入了一个参数，b''，导致异常，此参数为发起http请求时的自定义请求头，应该传入字典类型或None

self.jenkins_open(requests.Request('POST',
	self._build_url(WIPEOUT_JOB_WORKSPACE,
                    locals()), b''))

去掉b''即可正常使用

self.jenkins_open(requests.Request('POST',
	self._build_url(WIPEOUT_JOB_WORKSPACE,
                    locals())))

工具简介
python-jenkins是一个通过Jenkins REST API来操作Jenkins的python模块，安装方法

pip install python-jenkins
