从Jenkins REST查询中检索参数 [英] Retrieve parameter from a Jenkins REST query
问题描述
以下REST查询将返回上一次成功构建作业的参数:
https://localhost/job/test1/lastSuccessfulBuild/api/json
我想检索此构建的参数之一BUILD_VERSION:
The following REST query will return parameters of the last successful build of a job:
https://localhost/job/test1/lastSuccessfulBuild/api/json
I'd be interested to retrieve one of the parameters of this build, the BUILD_VERSION:
{
"_class": "org.jenkinsci.plugins.workflow.job.WorkflowRun",
"actions": [
{
"_class": "hudson.model.CauseAction",
"causes": [
{
"_class": "hudson.model.Cause$UpstreamCause",
"shortDescription": "Started by upstream project \"continuous-testing-pipeline-for-nightly\" build number 114",
"upstreamBuild": 114,
"upstreamProject": "continuous-testing-pipeline-for-nightly",
"upstreamUrl": "job/continuous-testing-pipeline-for-nightly/"
}
]
},
{ },
{
"_class": "hudson.model.ParametersAction",
"parameters": [
{
"_class": "hudson.model.StringParameterValue",
"name": "BUILD_VERSION",
"value": "1.1.15"
是否可以使用REST Api直接检索BUILD_VERSION(1.1.15),还是必须手动解析json字符串? 谢谢
Is there a way to retrieve the BUILD_VERSION (1.1.15) directly using the REST Api or do I have to parse manually the json string ? Thanks
推荐答案
是的,您可以获取该值,但是它仅适用于XML API :(
JSON API将使用Tree:)
Yeah you can get the value,But it will only work for XML API :(
The JSON API will return a simplified json object using Tree :)
因此,Jenkins为您提供了api(XML,JSON,PYTHON),您可以从中读取任何项目的Jenkins相关数据. https://localhost/job/test1/lastSuccessfulBuild/api
So Jenkins provides you with api (XML,JSON,PYTHON) from which you can read the Jenkins related data of any project. Documentation in detail is provide in https://localhost/job/test1/lastSuccessfulBuild/api
其中明确指出
In that it clearly states that
-
XML API -使用XPath控制所需的片段.例如,../api/xml?xpath =// [0]
XML API - Use XPath to control the fragment you want.For example, ../api/xml?xpath=//[0]
JSON API -使用树
Python API -使用st.literal_eval(urllib.urlopen("...").read())
Python API - Use st.literal_eval(urllib.urlopen("...").read())
以上所有内容均可用于从您从API获取的整个凌乱数据中获取特定片段/片段.
All the above can be used to get a specific fragment/piece from the entire messy data that you get from the API.
在您的情况下,出于明显的原因,我们将使用tree:)
In your case, we will use tree for obvious reasons :)
语法: tree=keyname[field1,field2,subkeyname[subfield1]]
为了获取BUILD_VERSION即值
In order to retrieve BUILD_VERSION i.e. value
//jenkins/job/myjob/../api/json?tree=lastSuccessfulBuild[parameters[value]]
上面的内容应该可以为您提供所需的东西,但是需要一点点的麻烦和错误:)
The above should get you what you want, but a bit of trail and error is required :)
