Google Apps脚本和外部API

Question

如果我没有弄错，按UrlFetch Documentation我应该可以在Google Apps脚本中调用New Basecamp API。我怀疑我的困惑来自格式化的GAS错误（以及我刚开始这一切的事实）。我已经搜索了很久。这是我和错误，我回去从气：

mycode的气体：

function myFunction() { 
    var url = "https://basecamp.com/******/api/v1/projects.json"; 
    var headers = { 
       "contentType": "application/json", 
       "headers":{ "User-Agent": "MY_APP_NAME", 
          "username:password" : "user:pass"}, 
       "validateHttpsCertificates" :false 
       }; 

var response = UrlFetchApp.fetch(url, headers); 
var text = response.getResponseCode(); 
Logger.log(text); 
} 

GAS错误消息：

Request failed for https://basecamp.com/2166446/api/v1/projects.json returned code 401. 
Server response: HTTP Basic: Access denied. (line 9, file "Code") 

我希望这是一个合理的问题，谢谢寻求帮助。

正确的标题为HTTP Basic Authentication，这使得Utilities.base64Encode使用，如下：

"headers": { 
    "User-Agent": "MY_APP_NAME (App URL/your email address)", 
    "Authorization": "Basic " + Utilities.base64Encode(username + ":" + password) 
},
