我有一个脚本化的管道，可以使用该input功能请求用户的密码，并将其与用户保存的凭据密码短语进行比较。如果用户输入是一种类型，string则可以使用。但是，当我将输入类型更改为password（因此用户输入时在屏幕上看不到该输入类型）时，它将失败并显示断言错误。

我确保输入与凭证文件中的密码匹配的密码。

我正在将Jenkins 2.83与最新的Credentials插件和Credentials绑定插件一起使用。

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，如果我将password输入参数更改为string，则可以使用：

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/处理输入的参数password变量/名称？
