Jenkins-将数组/列表传递给参数化的远程构建

问题描述

我正在使用Jenkins通过Publish Over SSH命令远程运行Ansible剧本.

I am using Jenkins to remotely run an Ansible playbook via the Publish Over SSH command.

此命令:

curl -k -v -X POST https://jenkins.myhost.com/job/Ansible_Deploy/build?token=<appToken> --user <myUser>:<userToken> --data-urlencode json='{"parameter":[{"name":"thisIsAList","value":["one","two","three"]}]}'

应触发生成后操作，以通过SSH远程执行以下命令:

should trigger a post-build action to remotely execute the following command over SSH:

ansible-playbook /home/<myUser>/test/practice.yml --extra-vars "thisIsAList=$thisIsAList"

thisIsAList是作业通知"下的字符串参数，并且已对作业进行了参数化.我已经成功执行了类似的命令，但是由于值是一个列表，因此该命令失败了.我尝试了字符串参数"和多行字符串参数"都无济于事.

thisIsAList is a string parameter under Job Notifications, and the job is parameterized. I have successfully executed similar commands, but this one fails, assumingly because the value is a list. I have tried both "String Parameter" as well as "Multi-line String Parameter" to no avail.

这是堆栈跟踪:

        at hudson.model.StringParameterDefinition.createValue(StringParameterDefinition.java:88)
        at hudson.model.ParametersDefinitionProperty._doBuild(ParametersDefinitionProperty.java:165)

注意:这可能是，但未得到有效的响应.

推荐答案

由于在Jenkins或Ansible文档中的任何地方都没有详细介绍此嵌套级别，因此，在解决问题后，我将对该主题进行一些说明.

Since this level of nesting isn't detailed anywhere in the Jenkins or Ansible documentation I'll shed some light on the topic now that I've solved my issue.

命令:

ansible-playbook /home/<myUsr>/test/practice.yml --extra-vars "thisIsAList=$thisIsAList"

应该已经将thisIsAList声明为字典对象.即:

Should have declared thisIsAList to be a dictionary object. I.e.:

ansible-playbook /home/<myUsr>/test/practice.yml --extra-vars "{thisIsAList=$thisIsAList}"

此外，cURL命令中的数据的格式应如下所示:

Furthermore, the data in the cURL command should've been formatted differently like so:

json='{"parameter":[{"name":"thisIsAList","value":"[one,two,three]"}]}'

注意:双引号位于整个列表中，而不是各个元素.

Note: the double-quotes are around the whole list, rather than the individual elements.

最后，对于其他嵌套项(例如列表中的dict)，您必须像这样对双引号进行转义:

Finally, with further nested items (such as dict inside a list) you have to escape the double-quotes like so:

{"parameter":[{"name":"thisIsADictNestedInAList","value":"[{\"name\":\"numbers\",\"value\":[1s, 2s, 3s]}]"}]}

似乎，在此嵌套级别，不再需要对列表加双引号；可能是因为向上一级的引号已经导致其被正确解释.

It seems, that at this level of nesting, it is no longer required to double-quote the lists; probably because the quotes one level up already lead it to be interpreted correctly.
