我有一个非常简单的Jenkins pipline代码-从文本中读取属性，并在循环中调用httpRequest将这组属性发送到服务器。然而，无论何时在循环中调用httpRequest，jenkins都会抛出此异常，几乎不可能判断错误是什么。

如果我将httpRequest移到循环之外，它会工作得很好-但是不确定如何迭代和发布所有属性。

props = readProperties text:"hello1=world1\nhello2=world2"

for (prop in props) {
    String name = prop.key
    String value = prop.value
    println "prop $name is $value"
    httpRequest  httpMode: 'POST', url: "http://myUrl", requestBody: "Name=$name&Value=$value",  contentType: 'APPLICATION_FORM'

}

例外情况是：

我安装了这个plugin并创建了以下管道(当然，在没有更多信息的情况下，我无法测试请求，但显示了迭代)。

pipeline {
    agent any 

    stages {
        stage('test'){
            steps {
                script {
                    def props = readProperties text:"hello1=world1\nhello2=world2"
                    for (prop in props) {
                        String name = prop.key
                        String value = prop.value
                        println "prop $name is $value"
                        //httpRequest  httpMode: 'POST', url: "http://myUrl", requestBody: "Name=$name&Value=$value",  contentType: 'APPLICATION_FORM'
                    }
                }
            }
        }
    }  
}

您会得到异常不可序列化异常，因为Jenkins会不时地将流水线上的当前状态保存到磁盘，并假设env中的每个对象都是可序列化的。

不幸的是，HashMap$Node是不可序列化的，因此您必须执行其他操作。我建议

def props = readProperties text:"hello1=world1\nhello2=world2"

for(def key : props.keySet()){
     def value = props.get(key)
     println "prop $key is $value"
}
