从系统帐户为用户创建ServiceAccountCredential

Question

我使用以下代码通过系统登录名（域范围验证）代表用户执行操作。我发现的唯一例子是使用反射来设置用户。我知道这是不是做到这一点，所以我在想，如果有人可以帮助我的这个应该怎么解决的例子有道

ServiceAccountCredential credential = 
    GoogleCredential.FromJson(GOOGLE_SYSTEM_USER_AUTH_INFORMATION) 
     .CreateScoped(Scopes) 
     .UnderlyingCredential as ServiceAccountCredential; 

var userField = typeof(ServiceAccountCredential).GetField("user", 
BindingFlags.NonPublic | BindingFlags.Instance); 
userField?.SetValue(credential, GOOGLE_CALENDAR_USERNAME); //Act in the guise of the normal user GOOGLE_CALENDAR_USERNAME 


service = new CalendarService(new BaseClientService.Initializer() 
{ 
    HttpClientInitializer = credential, 
    ApplicationName = ApplicationName, 
}); 

Answer 1

这是我怎么会做它，同时设置范围并通过ServiceAccountCredential.Initializer同时新用户：

ServiceAccountCredential original = (ServiceAccountCredential) 
    GoogleCredential.FromJson(GOOGLE_SYSTEM_USER_AUTH_INFORMATION).UnderlyingCredential; 

var initializer = new ServiceAccountCredential.Initializer(original.Id) 
{ 
    User = GOOGLE_CALENDAR_USERNAME, 
    Key = original.Key, 
    Scopes = Scopes 
}; 
var credentialForUser = new ServiceAccountCredential(initializer); 

现在给你一个ServiceAccountCredential而非GoogleCredential。这就是你当前的代码使用，所以它应该没问题 - 但如果有一个简单的方法获得GoogleCredential，那也不错。我们应该使这一切都更简单 - 我为filed an issue。
