对JenkinsAPI(https)的调用刚刚挂起 [英] Call to JenkinsAPI(https) just hangs

问题描述

我的代码在下面给出

from jenkinsapi.jenkins import Jenkins

def get_server_instance():
    jenkins_url = 'https://<privateJenkinsServer>:<port>'
    print "Hello" 
   server = Jenkins(jenkins_url, username = 'foouser', password = 'foopassword')
    return server

if __name__ == '__main__':
    print get_server_instance().version

执行此操作时，它只会打印"Hello" ，然后挂起.这可能是什么原因?

When I execute this, it just prints "Hello" and then hangs. What could be the reason for this ?

我正在代理服务器后面的公司网络中运行它.

N.B. I am running this in my corporate network behind a proxy.

参考: http://pythonhosted.org /jenkinsapi/using_jenkinsapi.html#example-1-get-version-of-jenkins

我终止该命令时，出现以下错误.

When I killed the command, I get the following error.

File "C:\Python27\lib\ssl.py", line 643, in read
    v = self._sslobj.read(len)

推荐答案

v = self._sslobj.read(len)上的错误表示您在读取过程中被打断了.它似乎完全没有文件记录，但jenkinsapi会在每项工作开始时尝试下载信息，如果您的Jenkins回购交易量巨大，那将是一辈子的事情.可以设置lazy = True，但是当您尝试访问单个作业时，它仍将尝试加载所有作业.使用其他一些库可能更好.

The error on v = self._sslobj.read(len) implies you interrupted while read was in progress. It seems to be completely undocumented, but jenkinsapi tries to download information on every job when it starts and if your Jenkins repo is huge it's gonna take forever. It's possible to set lazy=True but it will still try to load all the jobs when you try to access a single job. Probably better to use some other library.

server = Jenkins(jenkins_url, username = 'foouser', password = 'foopassword', lazy=True)
