Question

我有一个简单的共享库，可以执行http GET。这些文件存储在vars目录中： simpleHttpGet.groovy

String call(String rawUrl){
    new URL(rawUrl).text
}

httpGet.groovy

String call(String rawUrl){
    URL url = new URL(rawUrl)
    HttpURLConnection connection = url.openConnection()
    connection.setRequestMethod("GET")
    connection.setConnectTimeout(1000)
    connection.setDoInput(true)
    def text = null
    try {
        echo 'trying to connect'
        connection.connect()
        echo 'connected'
        def stream = connection.getInputStream()
        echo "stream $stream"
        text = stream.text
    } finally {
        echo 'disconnected'
        connection.disconnect()
    }
    echo text
    return text
}

当我在管道中使用simpleHttpGet.groovy和httpGet.groovy时，第一个返回null，第二个返回null InputStream。为什么不起作用？有完整的管道和执行结果。

@Library('simple-http-get') _
pipeline {
    agent any

    options {
        timestamps()
    }

    stages {
        stage('Test') {
            steps {
                script {
                    echo 'curl'
                    def curlResponse = sh(script: 'curl -X GET https://google.com', returnStdout: true)
                    echo curlResponse
                    echo 'simpleHttpGet'
                    def simpleResponse = simpleHttpGet('https://google.com')
                    echo simpleResponse
                    echo 'httpGet'
                    def httpGetResponse = httpGet("https://google.com")
                    echo httpGetResponse
                }
            }
        }
    }
}

为什么我无法在jenkins共享库中使用URL，HttpUrlConnection？
