我在我的网站上使用谷歌配置API。我想使用AppsService类对用户进行身份验证。
AppsService service = new AppsService("domain", "admin username", "admin password");
UserEntry user = service.RetrieveUser("username");
但它抛出异常:执行请求失败:https://apps-apis.google.com/a/feeds/pmu.mygbiz.com/user/2.0/username
InnerException是:远程服务器返回错误:(503)服务器 不可用。
它在6个月前开始工作。
答案 0 :(得分:0)
ClientLogin(登录名和密码)已于2012年4月20日弃用,并于2015年5月26日关闭。此代码将无法再使用Oauth2进行切换。
我认为您还需要切换到管理目录api
PM> Install-Package Google.Apis.Admin.Directory.directory_v1
更新代码:
我可以给你一些示例代码,但我不能100%测试它没有应用程序域。
助手类:

return service;
}
catch (Exception ex)
{
Console.WriteLine(ex.InnerException);
return null;
}

return service;
}
catch (Exception ex)
{
Console.WriteLine(ex.InnerException);
return null;
}
}
}
验证:
var service = AuthenticationHelper.AuthenticateOauth("xxxxx-d0vpdthl4ms0soutcrpe036ckqn7rfpn.apps.googleusercontent.com", "NDmluNfTgUk6wgmy7cFo64RV", "userID");
提出请求:
try
{
var userList = service.Users.List();
userList.MaxResults = 10;
userList.Execute();
}
catch (Exception ex)
{
Console.WriteLine(ex.Message);
}
Console.ReadLine();
