Google Drive API Files.List() 错误 invalid_grant 错误请求

Question

我正在使用 Google APIs Drive v3 并通过一个简单的请求来查找具有特定 ID 的文件夹，然后列出该文件夹中的所有文件。

但是根据请求执行它正在创建异常：

“Error: invalid_grant, Description: Bad Request, Uri:”

它曾经工作，但在上个月的某个时间停止了大约。当我在做另一个项目时。

我检查了 API 控制台，并且我们的客户端 ID 已注册（我已经散列了 ID、秘密和刷新令牌），并且在创建服务时一切似乎都正常，它正在发送不工作的请求。

但是查询过去可以工作，我已经尝试更改查询，但仍然无法正常工作。

代码如下，任何有关如何解决此问题的建议将不胜感激。谢谢

请求文件列表

    List<File> fileList = new List<File>();
        List<File> FileList_Lst_Ordered = new List<File>();
        try
        {
            string pageToken = null;
            do
            {
                request.Q = "'" + folderId + "' in parents";
                //request.Q = String.Format("name='{0}'", "Release Scripts Folder");
                //request.Q = "mimeType = 'application/vnd.google-apps.folder' + title='" + folderId +"'";

                request.Spaces = "drive";
                request.Fields = "nextPageToken, files(id, name, mimeType, trashed)";
                request.PageToken = pageToken;

                var result = request.Execute();

                // Iterate through files
                foreach (File file in result.Files)
                {
                    // If it is a matching type (or we are retreiving all files)
                    if (!(bool)file.Trashed && (file.MimeType == type || type == "ALL"))
                    {
                        fileList.Add(file);
                    }

                    //RST_00001
                    else if (!(bool)file.Trashed && (file.MimeType == "sql" || file.MimeType == "text/x-sql"))
                    {
                        fileList.Add(file);
                    }
                }

                // Increment file token
                pageToken = result.NextPageToken;
            } while (pageToken != null);

            //RST_00002: Order List Alphabetically
            int Counter_int = fileList.Count();
            for (int i = 1; i <= Counter_int; i++)
            {
                FileList_Lst_Ordered.Add(fileList.OrderBy(x => x.Name).FirstOrDefault());
                fileList.Remove(fileList.OrderBy(x => x.Name).FirstOrDefault());
            }

        }
        catch (Exception Ex)
        {
            errorString = Ex.Message;
            Helpers.Helpers_TextFile.TextFile_WriteTo(Log_Filename, "Error Occured While Obtaining script list for folder " + folderId + ", full error: " + Ex.ToString());
        }

在 GoogUtils.cs Helper 中初始化服务

        public static DriveService InitService(ref string errorString)
                {
                    try {
                        var token = new TokenResponse { RefreshToken = "###" };
                        var credentials = new UserCredential(new GoogleAuthorizationCodeFlow(
                            new GoogleAuthorizationCodeFlow.Initializer
                            {
                                ClientSecrets = new ClientSecrets
                                {
                                    ClientId = "###",
                                    ClientSecret = "###"
                                }
                            }),
                            "user",
                            token);

                        // Create Drive API service.
                        var service = new DriveService(new BaseClientService.Initializer()
                        {
                            HttpClientInitializer = credentials,
                            ApplicationName = ApplicationName,
                        });

                        return service;
                    }
                    catch (Exception e)
                    {
                        errorString = e.Message;
                    }

                    return null;
                }

我已经能够解决问题。通过重写服务使其使用 GoogleWebAuthorizationBroker.AuthorizeAsync 而不是 GoogleAuthorizationCodeFlow，我现在还从 JSON 加载凭据。见吹。 感谢大家的贡献和帮助：

 public static DriveService InitService(ref string errorString, string Log_Filename)
    {
        try
        {
            string[] Scopes = { DriveService.Scope.DriveReadonly };
            UserCredential credential;

            if (!System.IO.File.Exists(credential_json))
            {
                System.Windows.Forms.MessageBox.Show("Unable to Initialise Google Drives Service credentials not found.");
                Helpers.Helpers_TextFile.TextFile_WriteTo(Log_Filename, "Google Drive Init - Unable to Initialise Google Drives Service credentials not found.");
            }

            using (var stream = new FileStream(credential_json, FileMode.Open, FileAccess.Read))
            {
                string credPath = "token.json";
                credential = GoogleWebAuthorizationBroker.AuthorizeAsync(
                    GoogleClientSecrets.Load(stream).Secrets,
                    Scopes,
                    "user",
                    CancellationToken.None,
                    new FileDataStore(credPath, true)).Result;
                if (credential.UserId == "user")
                {
                    Helpers.Helpers_TextFile.TextFile_WriteTo(Log_Filename, "Google Drive Init - Credentials file saved to: " + credPath);
                }
                else {
                    Helpers.Helpers_TextFile.TextFile_WriteTo(Log_Filename, "Google Drive Init - Unable to verify credentials.");
                    return null;
                }
            }

            // Create Drive API service
            var service = new DriveService(new BaseClientService.Initializer()
            {
                HttpClientInitializer = credential,
                ApplicationName = ApplicationName,
            });

            // Validate Service
            if (service.Name == "drive" && service.ApplicationName == ApplicationName)
            {
                Helpers.Helpers_TextFile.TextFile_WriteTo(Log_Filename, "Google Drive Init - Google Service Created.");
            }
            else
            {
                Helpers.Helpers_TextFile.TextFile_WriteTo(Log_Filename, "Google Drive Init - Unable to create service.");
                return null;
            }

            return service;
        }
        catch (Exception Ex)
        {
            System.Windows.Forms.MessageBox.Show("An Error Occured While Initialising Google Drives Service");
            System.Windows.Forms.Clipboard.SetText(Ex.ToString());
            Helpers.Helpers_TextFile.TextFile_WriteTo(Log_Filename, "Google Drive Init - Error Occurred: " + Ex.ToString());
            errorString = Ex.Message;
        }

        return null;
    }
