问如何在google drive中使用触发器创建自定义对象的新文件夹？

EN

public static void createFolder(String folderName, String accessToken) {
    HttpRequest req = new HttpRequest();
    req.setMethod('POST');     
    req.setEndpoint('https://www.googleapis.com/drive/v3/files');
    req.setHeader('Authorization', 'Bearer '+accessToken);
    req.setHeader('content-type', 'application/json');
    String body = '{"name" : "'+ folderName +'","mimeType" : "application/vnd.google-apps.folder"}';
    req.setTimeout(60*1000);
    req.setBody(body);
    Http http = new Http();
    HttpResponse res = http.send(req);
    System.debug('===== Response==='+ res.getBody());
}
