jenkins: pass multiple "Extended Choice Parameter" values using a URL

Question

One of the parameters in my Jenkins build is an Extended Choice Parameter which is submitted as a selection of comma separated values when invoking the build from the build webpage.

However, I also need to invoke the build using wget + URL.

So, in the format:

wget "${JENKINS_URL}/job/buildname/buildWithParameters?ECP_LIST=blah1&token=token"

Say my Extended Choice Parameter ECP_LIST has possible values: blah1, blah2, blah3, blah4.

if I invoke, for example:

wget "${JENKINS_URL}/job/buildname/buildWithParameters?ECP_LIST=blah3&token=token"

the build starts fine with value blah3 for the EPC_LIST parameter.

However, if I wish to invoke it with 2 or more values, it just passes a blank value to the parameter.

I've tried separating the values using various things, like spaces, encoded comma, semi-colon. I haven't had any luck finding an answer here or on Google either.

Answer 1

I did solve it by selecting ECP_LIST multiple times:

wget "${JENKINS_URL}/job/buildname/buildWithParameters?ECP_LIST=blah1&ECP_LIST=blah2&ECP_LIST=blah3&token=token"

Will result in:

ECP_LIST=blah1,blah2,blah3

I hope that works for you.

You need to encode your URL before you pass it to wget I think, if your parameters contain special chars. I do it like this in python. I use curl.

url_params = {'param1' : param_value1, 'param2' : param_value2}
params_encoded = urllib.urlencode(url_params)
params = ['curl.exe', '-v', '-X', 'POST', '--show-error', '%s?%s' % (JobUrl), params_encoded]
subprocess.check_call(params)

Answer 3

Including the URL in single quotes work:

wget '${JENKINS_URL}/job/buildname/buildWithParameters?ECP_LIST=blah3&token=token'

Similarly if you want to run a curl through your Jenkins API with curl you would run:

curl -X POST 'http://api:[email protected]/job/BUILDNAME/buildWithParameters?parameter2=blah&parameter2=blahblah'
