get python version_python-jenkins：调用get_version()提示Error communicating with server

欢迎关注我的微信公众号：「阿拉平平」

报错说明

首先贴一下自己写的脚本：

# -*- coding: utf-8 -*-

import jenkins

class JenkinsAPI:

"""

Installing:

pip install python-jenkins

Import:

import jenkins

"""

def __init__(self):

self.url = 'http://127.0.0.1:8080/'

self.username = 'admin'

self.password = 'admin'

self.server = self._connect()

def _connect(self):

return jenkins.Jenkins(self.url, username=self.username, password=self.password)

def get_version(self):

"""get jenkins version"""

print(self.server.get_version())

if __name__ == '__main__':

jenkins_obj = JenkinsAPI()

jenkins_obj.get_version()

执行脚本报错如下：

During handling of the above exception, another exception occurred:

Traceback (most recent call last):

File "test.py", line 30, in

jenkins_obj.get_version()

File "test.py", line 25, in get_version

print(self.server.get_version())

File "/data/temp_venv/lib/python3.6/site-packages/jenkins/__init__.py", line 812, in get_version

% self.server)

jenkins.BadHTTPException: Error communicating with server[http://127.0.0.1:8080/]

解决方法

方法一：修改Jenkins的全局安全设置

如图所示：勾选 匿名用户具有可读权限 选项即可

方法二：在代码中加入一个认证方法

在_init_()方法中，加上了self.server.get_whoami() 由于该方法能够有认证信息，所以再调用get_verson() 就可以获取到

def __init__(self):

self.url = 'http://127.0.0.1:8080/'

self.username = 'admin'

self.password = 'admin'

self.server = self._connect()

self.server.get_whoami()

方法三：修改源码

源码位置在：site-packages/jenkins/__init__.py,找到get_version方法，代码从

def get_version(self):

try:

request = requests.Request('GET', self._build_url(''))

request.headers['X-Jenkins'] = '0.0'

response = self._response_handler(self._request(request))

return response.headers['X-Jenkins']

except (req_exc.HTTPError, BadStatusLine):

raise BadHTTPException("Error communicating with server[%s]"

% self.server)

改为：

def get_version(self):

try:

self._maybe_add_auth() # 添加这句即可

request = requests.Request('GET', self._build_url(''))

request.headers['X-Jenkins'] = '0.0'

response = self._response_handler(self._request(request))

return response.headers['X-Jenkins']

except (req_exc.HTTPError, BadStatusLine):

raise BadHTTPException("Error communicating with server[%s]"

% self.server)

写在后面

之后我查看了一下模块的源码，发现代码有所差异。我本地安装的是1.1.0，而博客中使用的应该是0.4的版本，修改方法并不适用高版本。

抽空又看了下源码，已补上修改源码的方法。
