Question

我正在使用Google.net客户端库对Google API进行身份验证，此代码可在本地运行，但当我将其上传到我的服务器时出现此错误

“无法使用\”https://accounts.google.com/o/oauth2/v2/auth?access_type=offline&response_type=code&client_id=123&redirect_uri=http%3A%2F%2Flocalhost%3A54597%2Fauthorize%2F&scope=https%3A%2F%2Fwww.googleapis.com%2Fauth%2Fdrive \“启动浏览器以进行授权。有关详细信息，请参阅内部异常。”

我的代码

Google.Apis.Drive.v3.DriveService service = null; 尝试 { UserCredential凭证; // string strUploadFolder = ConfigurationManager.AppSettings [“UploadFolder”];

            string credPath = AppDomain.CurrentDomain.BaseDirectory;
            credPath = Path.Combine(credPath, ".credentials/drive-dotnet-quickstart.json");
            credential = GoogleWebAuthorizationBroker.AuthorizeAsync(
               new ClientSecrets
               {
                   ClientId = ConfigurationManager.AppSettings["client_id"],
                   ClientSecret = ConfigurationManager.AppSettings["client_secret"],
               },
                    Scopes,
                    "user",
                    CancellationToken.None,
                    new FileDataStore(credPath, true)).Result;

            // Create Drive API service.
            service = new Google.Apis.Drive.v3.DriveService(new BaseClientService.Initializer()
            {
                HttpClientInitializer = credential,
                ApplicationName = ApplicationName,
            });
        }
        catch (Exception ex)
        {
            throw;
        }
        return service;
