Jenkins pipeline httpRequest提供NotSerializableException

Question

我想做一个简单的httpRequest来获取一些json数据。当我使用httpRequest插件时，它给了我NotSerializableException。

我尝试添加@NonCPS，但没有效果。

我尝试直接返回httpRequest响应，但没有对变量赋值，但仍然得到该异常。

我试过做sh "curl 'https://xxxxxx/api/getUser'"，但我得到了类似的NotSerializableException。

我正在使用Jenkinsfile。Jenkins版本: 2.172

下面是我的Jenkins管道代码：

pipeline {
    agent any

    stages {....}
    post {
        always {
            handleBuildNotification()
        }
    }
}

def handleBuildNotification() {
    String emails = fetchUserEmails()
}

@NonCPS
def fetchUserEmails() {

    String httpResponse = httpRequest(url: 'https://xxxxxx/api/getUser')

    def jsonResponse = readJSON text: httpResponse.content;
    return jsonResponse.response.result
}

我得到的异常：

[Pipeline] httpRequest
HttpMethod: GET
URL: https://xxxxxx/api/getUser
Sending request to url: https://xxxxxx/api/getUser
Error when executing always post condition:

Answer 1

我在这里尝试做出一个明智的猜测:我打赌HTTP请求不会返回JSON字符串，要么必须传递登录凭据，要么需要传递适当的请求头，如Accept: application/json。该错误似乎来自JSON反序列化程序。

您可以在脚本中使用print httpResponse.content来调试响应体。
