Call to JenkinsAPI(https) just hangs

问题

My code is given below

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

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

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

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

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)

Complete log.

回答1:

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)
