Dart: HttpException: Failed to parse header value
我得到一个
HttpException: Failed to parse header value
使用 M2 发行版 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。然后以下代码会导致异常：
1 2 3 4 | 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); |

要使用 Google Drive SDK API，您可以使用适用于 Dart 的 Google APIs 客户端库，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，它可以作为替代方案。
