通过Jenkins API获得/检测Jenkins的Version

关于获得/检测Jenkins的Version,下面页面(Jenkins Remote access API)中有说明:

https://wiki.jenkins-ci.org/display/JENKINS/Remote+access+API

Detecting Jenkins version(检测Jenkins的Version)

To check the version of Jenkins, load the top page (or, as of 1.483, any …/api/* page too) and check for the X-Jenkins response header. 

This contains the version number of Jenkins, like “1.404” This is also a good way to check if an URL is a Jenkins URL.

使用的浏览器为Chrome,在Chrome中查看response header方法如下:

1、按F12,弹出对话框,按Network选项;

2、点击网址/jenkins/api/python,然后点击Header/Response Headers就可以了。

通过Jenkins API获得/检测Jenkins的Version

使用Python获取Jenkins Version的example如下:

import requests  jenkins_python_api_url = "http://localhost:8080/jenkins/api/python" response = requests.post(jenkins_python_api_url) print response.headers.get('x-jenkins')

运行结果如下:

1.592

注意:获取Jenkins的Version无需考虑认证情况(无论是否需要认证,都可以获得Jenkins的Version)

同时,通过查阅Jenkins的相关源码,可以得知ResponseHeader消息头中存储的”X-Jenkins”即为Jenkins.VERSION:

private void setHeaders(StaplerResponse rsp) {  rsp.setHeader("X-Jenkins", Jenkins.VERSION);  rsp.setHeader("X-Jenkins-Session", Jenkins.SESSION_HASH); }
