在jenkins groovy中执行'curl‘时出错

Question

我正在尝试使用Groovy和curl来使用他们的REST API来创建一个ServiceNow变更票据。每次运行Jenkins管道时，我都会收到以下错误

{“错误”：{“消息”：“读取请求异常”，“详细信息”：“无法解码: java.io.StringReader@90e4d8"}，”状态“：”失败“}

我在这里做错了什么？Jenkins版本2.150.2

    {
    node(){
        stage ('Create Change Request') {
            echo("Creating Change Request")

            sh(script: """curl  ${SERVICENOW_URL}/table/change_request \

该数据具有使用声明的某些变量。在变量名中。Groovy不支持替换双引号"“中声明的变量。替换所有具有的变量名。用单引号'‘表示。

希望如此，这会有所帮助
