问题解决提示

错误原因及修复步骤

1. 「unable to resolve class JSON」错误

代码里使用as JSON但未导入对应类，Groovy中无需手动将Map转为JSON类，直接让HTTP框架处理序列化即可，同时需导入http-builder的JSON类型常量。

2. 「No encoder found for request content type /」错误

RESTClient未正确识别你设置的Content-Type，需在post请求中明确指定contentType参数，让框架匹配对应的编码器。

修复后的完整代码

@Grab(group='org.codehaus.groovy.modules.http-builder', module='http-builder', version='0.7.1')
import groovyx.net.http.RESTClient
import static groovyx.net.http.ContentType.JSON

def call() {
    withCredentials([string(credentialsId: 'github-api-token', variable: 'GITHUB_ACCESS_TOKEN')]) {
        // 替换占位符为实际的GitHub地址、组织、仓库名、PR编号
        def apiUrl = "https://{GITHUB_URL}/api/v3/repos/{ORG}/{REPO}/issues/{PR_NUMBER}/comments"
        
        def client = new groovyx.net.http.RESTClient(apiUrl)
        client.headers['Authorization'] = "token ${GITHUB_ACCESS_TOKEN}"
        
        def response = client.post(
            contentType: JSON,
            body: [body: "comment via jenkins method"]
        )
        
        if (response.status == 201) {
            println "Comment added successfully to Pull Request"
        } else {
            println "Failed to add comment to Pull Request. Status code: ${response.status}, Response: ${response.data}"
        }
    }
}
