问题描述
软件级别:
- Jenkins 2.121.2
- 凭据插件2.1.18
- 凭证绑定插件1.16
- 普通证书插件1.4
我正在处理Freestyle项目(而不是管道)，并且希望对工作的主要处理使用Groovy命令构建步骤.
I am working with a Freestyle project (not a pipeline) and want to use a Groovy command build step for the job's main processing.
我正在尝试从用户凭证中获取用户名和密码，以便常规脚本可以将其用于各种CLI操作.我花了很多时间来寻找答案，但是我发现没有一个起作用.大多数人不清楚，许多人是针对管道的.
I am trying to obtain the userid and password from a user credential so the groovy script can use them for various CLI manipulations. I spent a lot of time searching for answers, but none of the ones I've found worked. Most were not clear, many were geared toward pipelines.
在这一点上，我将不胜感激.
I would greatly appreciate a little guidance at this point.
以下是血腥细节.
我创建了一个新的参数化Freestyle项目，在其中为用户名和密码"凭据添加了凭据参数.它默认为我通过凭据插件定义给Jenkins的凭据之一.如果绑定选择要显式使用的凭据，我不确定是否有必要.
I created a new parameterized Freestyle project in which I added a Credentials Parameter for a "Username and password" credential. It defaults to one of the credentials that I defined to Jenkins via the Credentials Plugin. I'm not sure this is necessary if the binding selects the credential to use explicitly.
我不确定在构建环境"部分中是否使用了使用秘密文本或文件"，尽管我不确定这对于用户名/密码样式绑定是必不可少的.
I checked "Use secret text(s) or file(s)" in the Build Environment section, although I'm not certain that is essential for a Username/password style binding.
我添加了用户名和密码(分隔)"绑定，并将USERID和PASSWORD设置为各自的变量.
I added a "Username and password (separated)" binding and set USERID and PASSWORD as the respective variables.
我的groovy命令窗口有以下一行:println("$ {USERID} $ {PASSWORD}")
My groovy command window has this sole line:println("${USERID} ${PASSWORD}")
建立工作时，出现此错误:
When I build the job, I get this error:
推荐答案
这两种方式都会将凭据注入环境变量，因此您可以从Groovy脚本的环境变量中访问它们，如下所示方式.
The both ways will inject the credential into Environment Variable, thus you can access them from Environment Variable in Groovy Script as following for both ways.
def env = System.getenv()
println env['auth']
println env['USERNAME']
println env['PASSSWORD']
但是两种方式的注入值都不同.
But the injected value of the both ways are different.
1)添加凭据作业参数供用户在运行作业时选择
通过这种方式，将插入credentialId，因此您将无法获得用户名和密码.
In this way, the credentialId is injected, so you not get the username and password.
credentialId example: 1dd4755a-9396-4819-9327-86f25650c7d7
2)使用凭据绑定
这样，用户名和密码就被注入了，我想这就是您想要的.
In this way, the username and password are injected, I think this is what you wanted.
def env = System.getenv()
def username = env['USERNAME']
def password = env['PASSSWORD']
def cmd = "curl -u $username:$password ...."
通过插件Execute Groovy script
