C# Google API Contact.SetPhoto

以下代码在尝试检索联系人时返回错误（403 禁止访问）。

Contact contact = cr.Retrieve<Contact>(contactURI);

我基于Google的配置文件API页面的这段代码。 https://developers.google.com/google-apps/profiles/。 我将不胜感激任何反馈。

RequestSettings settings = new RequestSettings("Add Profile Photo", "consumerKey", "consumerSecret", username, domain);
ContactsRequest cr = new ContactsRequest(settings);
Uri contactURI = new Uri("http://www.google.com/m8/feeds/profiles/domain/" + domain + "/full/" + username);
Contact contact = cr.Retrieve<Contact>(contactURI);
Stream outStream = File.OpenRead("C:''temp''profilePic.jpg");
try
{
    cr.SetPhoto(contact, outStream);
}
catch (GDataVersionConflictException e)
{
    throw new Exception("Exception setting photo: " + e.Message);
}
