Question

I am trying to use Node.js to programmatically build Jenkins jobs that take Git parameters.

I am sending the parameters as post data, as shown below. However, no ma

try this, it works for me:

var auth = 'Basic yourUserToken';
var jobOptions = {
    url:'jenkinsHostName:8080/jenkins/job/jobName/' +'build',
    method: 'POST',
    port: 8080
};

var parameter = {"parameter": [{"name":"ref", "value":"origin/master"}]};
var postData;
if (!_.isEmpty(parameter)) {

    var jsonParametersString = JSON.stringify(parameter);
    jobOptions.headers = {
        'Authorization':auth,
       'Content-Type': 'application/x-www-form-urlencoded',
    };

    jobOptions.url += '?token=jobRemoteTriggerToken';
    postData = "json="+jsonParametersString;

    console.log("postData = " + postData);
}   
var callback;
var responseCB;
makeRequest(jobOptions, callback, responseCB, postData) ;

It is based on your code. I removed the querystring - it seems that it returned an empty string when performed on the parameters object. I change /buildWithParameters to /build - it didn't work the other way.

In addition, verify that when you pass the 'Content-Length' in the header, it doesn't truncated your json parameters object (I removed it ).

also note that I used the user API token, that you can get at http://yourJenkinsUrl/me/configure and click the "Shown API Token" button.

Not sure about this, as I don't know Node.js -- but maybe this fits: the Jenkins remote access API indicates that the parameter entity in the json request must point to an array, even if there's just one parameter to be defined.

Does the change below fix the problem (note the angle brackets around parameters)?

var jsonParametersString = JSON.stringify({"parameter": [parameters]});
