使用Groovy集合与字符串格式完全匹配

Question

关于如何使用groovy集合匹配确切的字符串格式，我有一个问题。

   def createPullRequest(projectSlug, repoSlug, title, description, sourceBranch, targetBranch) {
    //this is reading in the array with the user names
    def names = BitbutkcetUtil.getGroupUsers(teamName, activeOnly)

            def prResponse = this.steps.httpRequest(
                    acceptType: 'APPLICATION_JSON',
                    authentication: this.userId,
                    contentType: 'APPLICATION_JSON',
                    httpMode: 'POST',
                    ignoreSslErrors: true,
                    quiet: true,
                    requestBody: """
                                {
                                    "title": "${title}",
                                    "description": "${description}",
                                    "state": "OPEN",
                                    "open": true,
                                    "closed": false,
                                    "fromRef": { "id": "${sourceBranch}" },
                                    "toRef": { "id": "${targetBranch}" },
                                    "locked": false,
                                    "reviewers": [
                                        //I want to replace this hardcoded names with the string values inside the array `names`
                                        { "user": { "name": "HardCoded1" } },
                                        { "user": { "name": "HardCoded2" } },
                                        { "user": { "name": "HardCoded3" } },
                                        { "user": { "name": "HardCoded4" } }
                                    ]
                                }
                            """,
                    responseHandle: 'STRING',
                    url: "https://bitbucket.absolute.com/rest/api/latest/projects/${projectSlug}/repos/${repoSlug}/pull-requests",
                    validResponseCodes: '200:299')
            def pullRequest = this.steps.readJSON(text: prResponse.content)
            prResponse.close()
            return pullRequest['id']
        }

我想要做的是将reviewers中的reviewers名称替换为数组names中的字符串元素。我想要使用这个集合，但我必须符合确切的格式。

 { "user": { "name": "HardCoded1" } },
 { "user": { "name": "HardCoded2" } },
 { "user": { "name": "HardCoded3" } },
 { "user": { "name": "HardCoded4" } }

现在，我有了[reviewers: names.collect{ [user: [name: it]] }]，它输出了以下内容：

[reviewers:[[user:[name:name1]],
[user:[name:name2]],
[user:[name:name3]],
[user:[name:name4]]]] 

如何使输出符合以下格式？

    "reviewers": [
  //I want to replace this hardcoded names with the string values inside the array `names`
    { "user": { "name": "HardCoded1" } },
    { "user": { "name": "HardCoded2" } },
    { "user": { "name": "HardCoded3" } },
    { "user": { "name": "HardCoded4" } }
    ]

任何帮助都将不胜感激！

您看到的是在映射元素列表上调用toString()方法的结果。对于有效的JSON表示，可以将collect()方法的结果传递给JsonOutput.toJSON()。就像这样：

requestBody: """
            {
                "title": "${title}",
                "description": "${description}",
                "state": "OPEN",
                "open": true,
                "closed": false,
                "fromRef": { "id": "${sourceBranch}" },
                "toRef": { "id": "${targetBranch}" },
                "locked": false,
                "reviewers": ${JsonOutput.toJson(names.collect{ [user: [name: it]] })}
            }
        """

当JsonOutput.toJSON()首次在Jenkins管道中使用时，可能需要脚本的批准。
