oauth-2.0 - Dart:HttpException:无法解析 header 值

Question

我得到一个

HttpException: Failed to parse header value

当使用 M2 release dart http和 oauth2库调用http.Client.get(Uri)方法时。我正在尝试使用API​​执行 File: get。我成功地将授权请求重定向到基于控制台的简单http服务器上，以获取 token 。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);

以下是完整的堆栈跟踪:

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

https://github.com/Scarygami/dart-google-oauth2-library是基于此构建的，它可以替代。
