如何更新Jenkins作业发布config.xml

最近，我想更新Cloudbees中的一些作业（未使用DSL定义），为每个作业添加一些属性。

好吧，我在使其工作时遇到了一些麻烦，这是我的注意事项（我使用的是Jenkins 1.651.2.1，但有可能它应与较早和较新的版本一起使用，例如jenkins 2）

没有安全性/没有身份验证

这是简单的部分：检索并重新发布配置

$ curl  http://localhost:8080/jenkins/job/pof/config.xml -o config.xml
$ curl  -X POST http://localhost:8080/jenkins/job/pof/config.xml --data-binary @config.xml

简单的安全性：使用用户名和密码

我现在假设您的Jenkins设置已设置安全性（ http：// localhost：8080 / jenkins / configureSecurity / –>启用安全性）

这意味着我们现在需要验证我们的两个请求：

curl -X GET http://anthony:anthony@localhost:8080/jenkins/job/pof/config.xml -o config.xml
curl -X POST http://anthony:anthony@localhost:8080/jenkins/job/pof/config.xml --data-binary "@config.xml"

简单的安全性：启用CSRF（滚动）

您还需要保护您的jenkins实例免受CSRF攻击（ http：// localhost：8080 / jenkins / configureSecurity / –> enable csrf crumb）

现在，这也意味着您的请求需要发送一个屑状值，无论是作为参数还是通过标头

如果您不这样做：

curl -X POST http://anthony:anthony@localhost:8080/jenkins/job/pof/config.xml --data-binary "@config.xml"

您会得到这样的错误：

<body><h2>HTTP ERROR 403</h2>
<p>Problem accessing /jenkins/job/pof/config.xml. Reason:
<pre>    No valid crumb was included in the request</pre></p><hr /><i><small>Powered by Jetty://</small></i><br/>

甚至：

<body><h1>HTTP Status 500 - </h1><HR size="1" noshade="noshade"><p><b>type</b> Exception report</p><p><b>message</b> <u></u></p><p><b>description</b> <u>The server encountered an internal error () that prevented it from fulfilling this request.</u></p><p><b>exception</b> <pre>java.io.IOException: Failed to persist config.xml

获得面包屑值：

您可以使用configure job页面来分配值：

curl http://anthony:anthony@localhost:8080/jenkins/job/pof/configure | sed -n 's/.*\.crumb", "\(.*\)").*/\1/p' > crumb.txt

但是，还有专门用于此的服务：

curl http://anthony:anthony@localhost:8080/jenkins/crumbIssuer/api/xml | sed -n 's/.*\(.*\)<\/crumb>.*/\1/p' > crumb.txt

使用面包屑值

curl -X POST http://anthony:anthony@localhost:8080/jenkins/job/pof/config.xml --data-binary "@config.xml" -data ".crumb=6bbabc426436b72ec35e5ad4a4344687"

哎呀，那没用

Caused by: java.lang.IllegalStateException: STREAMEDat org.eclipse.jetty.server.Request.getReader(Request.java:803)at javax.servlet.ServletRequestWrapper.getReader(ServletRequestWrapper.java:256)at hudson.model.AbstractItem.doConfigDotXml(AbstractItem.java:610)

我建议您使用标题发送面包屑：

curl -v -X POST http://anthony:anthony@localhost:8080/jenkins/job/pof/config.xml --data-binary "@config.xml" -H ".crumb: 6bbabc426436b72ec35e5ad4a4344687"

基于cookie的安全性（无用户名/密码）

在某些安装中（例如cloubees），您不能在请求中传递用户名和密码。我建议您改用cookie。

要检索它们，请检查通过身份验证的浏览器发送的cookie，例如chrome：

然后将此URL粘贴到您的shell中：

curl 'http://localhost:8080/jenkins/job/pof/config.xml' -H 'Pragma: no-cache' -H 'Accept-Encoding: gzip, deflate, sdch' -H 'Accept-Language: en-US,en;q=0.8,fr;q=0.6' -H 'Upgrade-Insecure-Requests: 1' -H 'User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11_4) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/50.0.2661.102 Safari/537.36' -H 'Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8' -H 'Referer: http://localhost:8080/jenkins/login?from=%2Fjenkins%2Fjob%2Fpof%2Fconfig.xml' -H 'Cookie: screenResolution=1440x900; JSESSIONID=XXXXX; JSESSIONID.XX=XXXX; screenResolution=1440x900' -H 'Connection: keep-alive' -H 'Cache-Control: no-cache' --compressed

当然，您仍然需要获取面包屑值：

curl 'http://localhost:8080/jenkins/crumbIssuer/api/xml' -H 'Pragma: no-cache' -H 'Accept-Encoding: gzip, deflate, sdch' -H 'Accept-Language: en-US,en;q=0.8,fr;q=0.6' -H 'Upgrade-Insecure-Requests: 1' -H 'User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11_4) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/50.0.2661.102 Safari/537.36' -H 'Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8' -H 'Referer: http://localhost:8080/jenkins/login?from=%2Fjenkins%2Fjob%2Fpof%2Fconfig.xml' -H 'Cookie: screenResolution=1440x900; JSESSIONID=XXXXX; JSESSIONID.XX=XXXXX; screenResolution=1440x900' -H 'Connection: keep-alive' -H 'Cache-Control: no-cache' --compressed | sed -n 's/.*<crumb>\(.*\)<\/crumb>.*/\1/p' > crumb.txt

现在，您可以发布更新的config.xml了：

curl -X POST 'http://localhost:8080/jenkins/job/pof/config.xml' -H 'Pragma: no-cache' -H 'Accept-Encoding: gzip, deflate, sdch' -H 'Accept-Language: en-US,en;q=0.8,fr;q=0.6' -H 'Upgrade-Insecure-Requests: 1' -H 'User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11_4) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/50.0.2661.102 Safari/537.36' -H 'Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8' -H 'Referer: http://localhost:8080/jenkins/login?from=%2Fjenkins%2Fjob%2Fpof%2Fconfig.xml' -H 'Cookie: screenResolution=1440x900; JSESSIONID=XXXX; JSESSIONID.XX=XXXX; screenResolution=1440x900' -H 'Connection: keep-alive' -H 'Cache-Control: no-cache' --compressed --data-binary "@config.xml" -H ".crumb: 6bbabc426436b72ec35e5ad4a4344687"
