在Jenkins管道中，执行相互身份验证REST请求的正确方式是什么？

pipeline {
    agent any
    
    stages {
        stage('REST Request') {
            steps {
                script {
                    def url = 'https://api.example.com/endpoint'
                    def username = 'your_username'
                    def password = 'your_password'
                    
                    // 使用HttpClient进行请求
                    def client = new groovyx.net.http.HTTPBuilder(url)
                    client.auth.basic(username, password)
                    def response = client.get(path: '/')

                    // 处理响应
                    if (response.status == 200) {
                        echo "请求成功！"
                        echo "响应内容：${response.data}"
                    } else {
                        error "请求失败！状态码：${response.status}"
                    }
                }
            }
        }
    }
}
