我得到了

HttpException：无法解析标头值

使用M2 release dart http和oauth2库调用http.Client.get（Uri）方法时。我正在尝试使用API来执行File: get。我成功地将我的授权请求重定向到一个简单的基于控制台的http服务器以获取令牌。然后，以下代码导致异常：

oauth.Credentials credentials = new oauth.Credentials(code);
http.Client client = new oauth.Client(CLIENT_ID, CLIENT_SECRET, credentials);
Uri uri = new Uri("https://www.googleapis.com/drive/v2/files/$fileID");
Future<http.Response> result = client.get(uri);

以下是完整堆栈跟踪：

Answer 1

要使用Google Drive SDK API，您可以使用Google APIs Client Library for Dart从Dart应用程序访问Google API。

https://github.com/Scarygami/dart-google-oauth2-library是基于此构建的，它可以作为替代方案。

Answer 2

您可能没有初始化SSL？

SecureSocket.initialize();

有关详细信息，请参阅http://api.dartlang.org/docs/bleeding_edge/dart_io/SecureSocket.html。
