HTTP Basic Authentication原来很easy，參考文档：http://zh.wikipedia.org/wiki/HTTP%E5%9F%BA%E6%9C%AC%E8%AE%A4%E8%AF%81

将username和password用：分隔，然后用base64编码。最后用HTTP GET方法请求页面

以下一小段代码用newLISP调用了Jenkins的Remote API:

dean@dean-beijing-home:~$ ./http.lsp

hello

http.lsp源码例如以下：

#!/usr/bin/newlisp

(println "hello")

(set 'user-pass "user:pwd")

(set 'auth (append "Authorization: Basic " (base64-enc user-pass) "\r\n"))

(set 'xml (get-url "http://your_jenkins/job/your_job/lastBuild/api/xml" 5000 auth))

(println xml)

(exit)

注意,get-url函数功能强大，这里的5000指的是超时时间，auth就是将编码后的username和password放在header里面发出去。
