我实现了我的自定义IDataStore
这样我就可以存储最终用户令牌 on my database而不是默认的实现,它保存在文件系统在%AppData%内。
public class GoogleIDataStore : IDataStore
{
...
public Task<T> GetAsync<T>(string key)
{
TaskCompletionSource<T> tcs = new TaskCompletionSource<T>();
var user = repository.GetUser(key.Replace("oauth_", ""));
var credentials = repository.GetCredentials(user.UserId);
if (key.StartsWith("oauth") || credentials == null)
{
tcs.SetResult(default(T));
}
else
{
var JsonData = Newtonsoft.Json.JsonConvert.SerializeObject(Map(credentials));
tcs.SetResult(NewtonsoftJsonSerializer.Instance.Deserialize<T>(JsonData));
}
return tcs.Task;
}
}
控制器
public async Task<ActionResult> AuthorizeDrive(CancellationToken cancellationToken)
{
var result = await new AuthorizationCodeMvcApp(this, new GoogleAppFlowMetadata()).
AuthorizeAsync(cancellationToken);
if (result.Credential == null)
return new RedirectResult(result.RedirectUri);
var driveService = new DriveService(new BaseClientService.Initializer
{
HttpClientInitializer = result.Credential,
ApplicationName = "My app"
});
//Example how to access drive files
var listReq = driveService.Files.List();
listReq.Fields = "items/title,items/id,items/createdDate,items/downloadUrl,items/exportLinks";
var list = listReq.Execute();
return RedirectToAction("Index", "Home");
}
该问题发生在重定向事件上。第一次重定向后,它工作正常。
我发现重定向事件有些不同。在重定向事件上T
不是令牌响应,而是字符串。此外,密钥以“oauth_”为前缀。
所以我认为我应该在重定向上返回不同的结果,但我不知道要返回什么。
我得到的错误是:Google.Apis.Auth.OAuth2.Responses.TokenResponseException:错误:“状态无效”,说明:“”,Uri:“”
