jira webhook 事件触发并程序代码调用jenkins接口触发构建操作

export class JenkinsController extends BaseController {
    public async jira_notify_jenkins_build() {
        const jenkinsAuthHeader = `Basic ${base64(jenkins_username + ':' + jenkins_userpwd)}`;
        var jenkinsBaseUrl = 'http://ip:8080/';//jenkins的地址
        var comment_name = req.body.issue.fields.components[0].name,//站点名称
            jira_issue_id = req.body.issue.key,//jira上面的任务id
            git_branch = req.body.issue.fields.customfield_10107//jira上面的自定义字段，存的是git 分支名称
            , env = req.body.issue.fields.status.name;//当前要构建的的环境名称
        //一些检查
        if (!req.body.changelog || !req.body.changelog.items || !req.body.changelog.items[0] || req.body.changelog.items[0].field !== 'status') {
            log.Info(`${comment_name} changelog not status ${JSON.stringify(req.body && req.body.changelog)}`)
            res.end();
            return;
        }
        if (env !== 'SIT' && env !== 'UAT' && env !== 'STG' && env !== 'PROD') {

            res.end();
            return;
        }
        //获得jenkins的crumb值，没有这玩意接口就不能调用
        var data = await ApiClient.Get<any>(jenkinsBaseUrl, 'crumbIssuer/api/json', undefined, { headers: { 'Authorization': jenkinsAuthHeader } });

        //组装接口调用要用到的参数
        var headers: any = {
