如何将新用户添加到 Google 日历的 ACL？我正在尝试发送一个 POST HTTP 请求。也许 XML 有问题？下面的代码会生成服务器错误 (400)。（编辑：显示 oAuth）。
//---------------------------------------------------------------
// Add a rule to the Access Control List for 'Fake Calendar 1.0'
//---------------------------------------------------------------
function addRule() {
// Get Calendar ID, script user's email, and the API Key for access to Calendar API
var calId = '12345calendar.google.com';
var userEmail = Session.getActiveUser().getEmail();
var API_KEY = 'ABC123';
var newUserEmail = 'person@example.net';
// Get authorization to access the Google Calendar API
var apiName = 'calendar';
var scope = 'https://www.googleapis.com/auth/calendar';
var fetchArgs = googleOAuth_(apiName, scope);
fetchArgs.method = 'POST';
var rawXML = "<entry xmlns='http://www.w3.org/2005/Atom' " +
"xmlns:gAcl='http://schemas.google.com/acl/2007'>" +
"<category scheme='http://schemas.google.com/g/2005#kind' " +
"term='http://schemas.google.com/acl/2007#accessRule'/>" +
"<gAcl:role value='owner'/>" +
"<gAcl:scope type='user' value='"+userEmail+"'/>" +
"</entry>";
fetchArgs.payload = rawXML;
fetchArgs.contentType = 'application/atom+xml';
// Get the requested content (the ACL for the calendar)
var base = 'https://www.googleapis.com/calendar/v3/calendars/';
var url = base + calId + '/acl?key=' + API_KEY;
var content = UrlFetchApp.fetch(url, fetchArgs).getContentText();
Logger.log(content);
}

function googleOAuth_(name,scope) {
var oAuthConfig = UrlFetchApp.addOAuthService(name);
oAuthConfig.setRequestTokenUrl("https://www.google.com/accounts/OAuthGetRequestToken?scope="+scope);
oAuthConfig.setAuthorizationUrl("https://www.google.com/accounts/OAuthAuthorizeToken");

oAuthConfig.setConsumerSecret("anonymous");
return {oAuthServiceName:name, oAuthUseToken:"always"};
