Question

我在jenkins官方码头中心的码头工具中使用Jenkins（但我甚至尝试过我们在bluemix实例上的jenkins）。

我正在编写程序（当前测试驱动）从java触发作业然后使用获取作业ID jenkins api。

Properties jenkinsProps = new Properties();
InputStream jenkinsPropsIs = Files.newInputStream(jenkinsPropsFilePath);
jenkinsProps.load(jenkinsPropsIs);

// for building url
String jenkinsServerUrl = jenkinsProps.getProperty(JenkinsPropertiesKeys.KEY_JENKINS_SERVER_URL);
String jobName = jenkinsProps.getProperty(JenkinsPropertiesKeys.KEY_JENKINS_JOB_NAME);
String jobRemoteAccessToken = jenkinsProps.getProperty(JenkinsPropertiesKeys.KEY_JENKINS_JOB_ACCESS_TOKEN);

// for headers
String jenkinsUser = jenkinsProps.getProperty(JenkinsPropertiesKeys.KEY_JENKINS_USERNAME);
String jenkinsUserApiToken = jenkinsProps.getProperty(JenkinsPropertiesKeys.KEY_JENKINS_API_TOKEN);
String jenkinsCrumb = jenkinsProps.getProperty(JenkinsPropertiesKeys.KEY_JENKINS_CSRF_CRUMB);

// build parameters
Map<String, String> params = new LinkedHashMap<>();
params.put("param1", "test1");
params.put("param2", "test2");
params.put("param3", "test3");

// Jenkins cause - to identify which process had run this job
String procID = UUID.randomUUID().toString();
params.put("cause", procID);

String url = getJenkinsBuildWithParametersUrl(jenkinsServerUrl, jobName, jobRemoteAccessToken, params);

WebRequest request = new WebRequest(); // own HttpConnection based client
// setup Jenkins crumb to avoid CSRF
request.setHeader(HEADER_NAME_JENKINS_CRUMB, jenkinsCrumb);

// user authentification (Basic + base64 encoded user:apiToken)
setupAuthenticationHeader(request, jenkinsUser, jenkinsUserApiToken);

// execute POST request
request = request.post(url);

// asserts
assertNotNull(request);
assertEquals(201, request.getResponseCode());


/* GET JOB ID */
Thread.currentThread().sleep(8000); // !!! if less then 8sec, jenkins returns old job number

request.reset();
setupAuthenticationHeader(request, jenkinsUser, jenkinsUserApiToken);
url = getJenkinsLastBuildUrl(jenkinsServerUrl, jobName);

// execute get request to /api/json
request = request.get(url);
assertTrue(request.isOK());

// get note & compare with proc id, to match job
String jenkinsJobProcId = null;
JsonObject jenkinsLastBuildJson = request.getResponseAsJson();
JsonArray jenkinsActions = jenkinsLastBuildJson.get("actions").getAsJsonArray();
for (JsonElement action : jenkinsActions) {
    JsonObject actionJson = action.getAsJsonObject();
    if (actionJson.get("_class").getAsString().equals("hudson.model.CauseAction")) {
        JsonArray causeActionJsonArray = actionJson.get("causes").getAsJsonArray();
        for (JsonElement cause : causeActionJsonArray) {
            JsonObject causeJson = cause.getAsJsonObject();
            if (causeJson.get("_class").getAsString().equals("hudson.model.Cause$RemoteCause")) {
                jenkinsJobProcId = causeJson.get("note").getAsString();
                break;
            }
        }
        if (!jenkinsJobProcId.isEmpty()) {
            break;
        }
    }
}
System.out.println("LastBuild prodId      : " + jenkinsJobProcId);
assertEquals(procID, jenkinsJobProcId);

// get jenkins build number
int lastBuildNumber = jenkinsLastBuildJson.get("number").getAsInt();
System.out.println("LastBuild buildNumber : " + lastBuildNumber);
assertTrue(lastBuildNumber > 0);

一旦我触发工作，需要8秒才能在/ api / json中工作。

你知道会出现什么问题吗？

如何调整它？

Answer 1

请检查两次执行之间是否还需要延迟。

触发工作

public class DigitalSignature : ContentPage
 {
        SignaturePadView sign = new SignaturePadView();

        public DigitalSignature()
        {
            Button btnOk = new Button
            {
                Text = "Ok",
                BackgroundColor = Color.FromHex("#ff6600"),
                HorizontalOptions = LayoutOptions.End,
                WidthRequest = 100,
                HeightRequest = 35,
                FontSize = 15
            };

            btnOk.Clicked += btnOk_Clicked;

            sign = new SignaturePadView()
            {
                SignatureLineColor = Color.Red,
                StrokeColor = Color.Black,
                StrokeWidth = 10f,
                HeightRequest = 150,
                BackgroundColor = Color.White,
                ClearText = "Clear Me"
            };
            sign.CaptionText = "pls sign here";


            Content = new StackLayout
            {
                Children = {
                    sign,
                    btnOk
                }
            };

        }

        private void btnOk_Clicked(object sender, EventArgs e)
        {

        }
    }

获取职位信息

curl -X POST http://${JENKINS_HOTS}:${JENKINS_PORT}/job/${JOB_NAME}/build \
  --user ${USER}:${PASSWORD} \
  --data-urlencode json='{"parameter": [{"name":"delay", "value":"0sec"}]}'

如果您仍需要等待大约8秒钟，请检查作业中curl http://${JENKINS_HOTS}:${JENKINS_PORT}/job/${JOB_NAME}/api/json \ --user ${USER}:${PASSWORD}的设置。如果尚未启用，请启用它并将期间设置为quiet period。这应该消除执行之间的延迟。

根据Jenkins实例的工作量，即使是零秒的时间段，您也可能需要等待一段时间。

詹金斯api太慢了
