我开始用Twitter撕掉我的头发并尝试登录用户!我有Facebook,谷歌,OpenId一切正常,只是Twitter是一个痛苦。
当我尝试运行我的代码时,我经常得到401 Unauthorized,因为我的生活无法找出原因。
我创建了一个推特客户端,并且我正在使用DotNetOpenAuth示例解决方案中的InMemoryTokenManager。我的Twitter客户端在这里
public class TwitterClient
{
private string UserName { get; set; }
private static readonly ServiceProviderDescription ServiceDescription =
new ServiceProviderDescription
{
RequestTokenEndpoint = new MessageReceivingEndpoint(
"https://api.twitter.com/oauth/request_token",
HttpDeliveryMethods.GetRequest |
HttpDeliveryMethods.AuthorizationHeaderRequest),
UserAuthorizationEndpoint = new MessageReceivingEndpoint(
"https://api.twitter.com/oauth/authorize",
HttpDeliveryMethods.GetRequest |
HttpDeliveryMethods.AuthorizationHeaderRequest),
AccessTokenEndpoint = new MessageReceivingEndpoint(
"https://api.twitter.com/oauth/access_token",
HttpDeliveryMethods.GetRequest |
HttpDeliveryMethods.AuthorizationHeaderRequest),
TamperProtectionElements = new ITamperProtectionChannelBindingElement[] { new HmacSha1SigningBindingElement() },
};
IConsumerTokenManager _tokenManager;
public TwitterClient(IConsumerTokenManager tokenManager)
{
_tokenManager = tokenManager;
}
public void StartAuthentication()
{
var request = HttpContext.Current.Request;
using (var twitter = new WebConsumer(ServiceDescription, _tokenManager))
{
var callBackUrl = new Uri(request.Url.Scheme + "://" + request.Url.Authority + "/Members/TwitterCallback");
twitter.Channel.Send(
twitter.PrepareRequestUserAuthorization(callBackUrl, null, null)
);
}
}
public bool FinishAuthentication()
{
using (var twitter = new WebConsumer(ServiceDescription, _tokenManager))
{
var accessTokenResponse = twitter.ProcessUserAuthorization();
if (accessTokenResponse != null)
{
UserName = accessTokenResponse.ExtraData["screen_name"];
return true;
}
}
return false;
}
}
我在MembersController的构造函数中有以下内容,它使用正确的凭据实例化InMemoryTokenManager
_tokenManager = new InMemoryTokenManager(ConfigUtils.GetAppSetting("TwitterAppId"), ConfigUtils.GetAppSetting("TwitterAppSecret"));
我的两个行动是
public ActionResult LogonTwitter()
{
var client = new TwitterClient(_tokenManager);
client.StartAuthentication();
return null;
}
public ActionResult TwitterCallback()
{
var client = new TwitterClient(_tokenManager);
if (client.FinishAuthentication())
{
return new RedirectResult("/");
}
// show error
return View("LogOn");
}
错误出现在我的TwitterClient中的 StartAuthentication()中。一旦它调用此行
twitter.Channel.Send(
twitter.PrepareRequestUserAuthorization(callBackUrl, null, null)
);
我收到以下错误
Error occurred while sending a direct message or getting the response.
Inner Exception: The remote server returned an error: (401) Unauthorized.
有人有什么建议吗?我昨天和今天早上的大部分时间都在试图对此进行排序。我尝试的所有在线示例似乎也得到401 Unauthorized返回? DotNetOpenAuth和Twitter是否存在已知问题?
非常感谢任何帮助。
答案 0 :(得分:5)
我不记得确切的术语,但你是否在twitter应用程序(以及代码)中设置了一个回调网址?我最近遇到过类似的问题,即使在本地开发我相信你需要设置这个值,即使它只是一个占位符
