我正在使用Google Apis Drive v3进行一个简单的请求，即查找具有特定ID的文件夹，然后列出该文件夹中的所有文件。
但是根据请求执行会创建异常：
“Error: invalid_grant, Description: Bad Request, Uri:”
它曾经可以工作，但在上个月的某个时候已停止运行。当我在另一个项目上工作时。
我已经检查了API控制台，并注册了我们的客户ID（我已经对ID，机密和刷新令牌进行了哈希处理），并且在创建服务并发送不起作用的请求时一切正常。
但是该查询曾经可以正常工作，但我尝试过更改该查询，但仍然无法正常工作。
代码在下面，有关如何解决此问题的任何建议将不胜感激。谢谢
List<File> fileList = new List<File>();
List<File> FileList_Lst_Ordered = new List<File>();
try
{
string pageToken = null;

request.Q = "'" + folderId + "' in parents";

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。见打击。 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;
