如何为Jenkins Pipeline动态设置选择参数

I’ve adjusted your pipeline to dynamically pull .zip artifact filenames from an API and use them as choices in the input prompt—here’s the modified code and a breakdown of how it works:

pipeline { 
    agent any 
    stages { 
        stage("Fetch Artifacts & Prompt Release") { 
            steps { 
                script {
                    // 1. Call your API to get the artifact list (replace with your actual endpoint)
                    def apiResponse = sh(
                        script: 'curl -s "https://your-api-endpoint/artifacts"',
                        returnStdout: true
                    ).trim()

                    // 2. Parse the response to extract only .zip filenames
                    // Adjust this parsing logic to match your API's output format
                    def artifactList = new groovy.json.JsonSlurper().parseText(apiResponse)
                    def zipArtifacts = artifactList.findAll { it.endsWith('.zip') }.join('\n')

                    // Fallback if no .zip artifacts are found (prevents input prompt failure)
                    if (zipArtifacts.isEmpty()) {
                        zipArtifacts = 'no-zip-artifacts-found'
                        echo "Warning: No .zip artifacts returned from the API"
                    }

                    // 3. Prompt user with dynamically generated choices
                    env.RELEASE_SCOPE = input(
                        message: 'Select the .zip artifact to release:',
                        ok: 'Proceed with Release!',
                        parameters: [
                            choice(
                                name: 'RELEASE_SCOPE',
                                choices: zipArtifacts,
                                description: 'Choose which artifact to deploy'
                            )
                        ]
                    )
                }
                echo "Selected artifact for release: ${env.RELEASE_SCOPE}"
            }
        } 
    } 
}

Key Details to Note: #

• API Call: The example uses curl to fetch the API response. If your Jenkins agent doesn’t have curl installed, or if you need to handle authentication/headers, use Jenkins’ HTTP Request Plugin for a native, configurable httpRequest step instead.
• Response Parsing: This code assumes your API returns a JSON array of filenames. If your API returns plain text (one filename per line), skip the JSON parsing and directly filter lines ending with .zip.
• Edge Case Handling: Added a fallback option to prevent the input prompt from failing if no .zip artifacts are returned—you can adjust this to abort the pipeline instead if that fits your workflow.
• Dynamic Choices: The choices parameter expects a newline-separated string, so we use join('\n') to convert our list of filenames into the required format.
