如何比较用户输入的密码和凭据密码短语

jenkins-groovy jenkins-pipeline groovy jenkins

Frak · 技术社区 · 7 年前

我有一个脚本管道,它使用 input 函数,并将其与用户保存的凭据密码短语进行比较。如果用户输入是类型 string 然后它就起作用了。但是,当我将输入类型更改为 password (因此,当用户键入它时,它在屏幕上不可见),它会失败,并出现断言错误。

我确保输入与凭据文件中的密码匹配的密码。

我正在使用Jenkins 2.83和最新的凭据插件和凭据绑定插件。

脚本:

node 
{
    stage ("Collect User Input")
    {
        userInput = input(  id: 'Input-username', 
                            message: 'Select username', 
                            ok: 'Continue', 
                            parameters: [choice(choices: 'user1\nuser2\nuser3', description: '', name: 'username'),
                                         password(defaultValue: '', description: 'Enter your private key passphrase ', name: 'password')
                                         ], 
                            submitterParameter: 'approver')


        println("User Input is: " + userInput)

        withCredentials(bindings: [sshUserPrivateKey(credentialsId: 'my-test-key', 
                                                   keyFileVariable: 'cred_keyfile',
                                                passphraseVariable: 'cred_passphrase',
                                                  usernameVariable: 'cred_username' )])
        {
            assert userInput.password==cred_passphrase
        }
    }
}

我得到错误:

但是,如果我更改 暗语 将参数输入到 一串 ,它的工作原理是:

string(defaultValue: '', description: 'Enter your private key passphrase here', name: 'password')

所以我的问题是,我应该如何访问/处理输入参数 暗语 变量/名称?

您的断言失败,因为输入类型 password 返回的不是字符串,而是 hudson.util.Secret 对象如果要将输入密码与 cred_passphrase 您应该这样做:

hudson.util.Secret.fromString(cred_passphrase) == userInput.password

转换是很重要的 cred\u密码短语 具有 Secret.fromString(data) 到a 哈德逊。util。秘密 对象,因为变量 cred\u密码短语 将您的密码短语作为纯文本保存在 String 。

下面你可以找到一个完整的例子。

node {
    stage ("Collect User Input") {
        userInput = input(  id: 'Input-username', 
                            message: 'Select username', 
                            ok: 'Continue', 
                            parameters: [choice(choices: 'user1\nuser2\nuser3', description: '', name: 'username'),
                                         password(defaultValue: '', description: 'Enter your private key passphrase ', name: 'password')
                                         ], 
                            submitterParameter: 'approver')


        println("User Input is: " + userInput)

        withCredentials(bindings: [sshUserPrivateKey(credentialsId: 'my-test-key', 
                                                   keyFileVariable: 'cred_keyfile',
                                                passphraseVariable: 'cred_passphrase',
                                                  usernameVariable: 'cred_username' )])
        {
            assert hudson.util.Secret.fromString(cred_passphrase) == userInput.password
        }
    }
}
