DotNetOpenauth Microsoft和Twitter自定义客户端

Question

我第一次使用DontNetOpenAuth。找到博客Custom LinkedIn OAuth Provider后，我创建了自己的linkedin自定义客户端，并更改了以下内容以获取更多详细信息

const string UserProfileFields = ":(id,first-name,last-name,headline,location:(name),picture-url,email-address,public-profile-url,phone-numbers,date-of-birth)";
protected override AuthenticationResult VerifyAuthenticationCore(AuthorizedTokenResponse response)            
{

                const string profileRequestUrl =
                    "https://api.linkedin.com/v1/people/~" + UserProfileFields;
............
}

它运作正常。我试图对MicrosoftClient和twitter客户端使用相同的概念，但两者都不起作用。我的推特客户端如下

   public class TwitterCustomClient : OAuthClient{
    private static XDocument LoadXDocumentFromStream(Stream stream)
        {
    .......
    }
private static readonly ServiceProviderDescription TwitterServiceDescription =
                new ServiceProviderDescription
                {
                    RequestTokenEndpoint = new MessageReceivingEndpoint(
                                               "https://api.twitter.com/oauth/request_token",
                                               HttpDeliveryMethods.GetRequest |
                                               HttpDeliveryMethods.PostRequest |                                               HttpDeliveryMethods.AuthorizationHeaderRequest),
                    UserAuthorizationEndpoint = new MessageReceivingEndpoint(
                                              "https://api.twitter.com/oauth/authorize",
                                              HttpDeliveryMethods.GetRequest |
                                              HttpDeliveryMethods.PostRequest |                                              HttpDeliveryMethods.AuthorizationHeaderRequest),
                    AccessTokenEndpoint = new MessageReceivingEndpoint(
                                              "https://api.twitter.com/oauth/access_token",
                                              HttpDeliveryMethods.GetRequest |
                                              HttpDeliveryMethods.PostRequest |                                              HttpDeliveryMethods.AuthorizationHeaderRequest),
                    TamperProtectionElements = new ITamperProtectionChannelBindingElement[] { new HmacSha1SigningBindingElement() },
};
public TwitterCustomClient(string consumerKey, string consumerSecret) :
                base("Twitter", TwitterServiceDescription, consumerKey, consumerSecret) { }
protected override AuthenticationResult VerifyAuthenticationCore(AuthorizedTokenResponse response)
            {
                const string profileRequestUrl =                    "https://api.twitter.com/1.1/";
                string accessToken = response.AccessToken;
                var profileEndpoint =
                    new MessageReceivingEndpoint(profileRequestUrl, HttpDeliveryMethods.GetRequest);
                HttpWebRequest request =
                    WebWorker.PrepareAuthorizedRequest(profileEndpoint, accessToken);
                try
                {
                    using (WebResponse profileResponse = request.GetResponse())
                    {
                        using (Stream responseStream = profileResponse.GetResponseStream())
                        {
                            XDocument document = LoadXDocumentFromStream(responseStream);
                            string userId = document.Root.Element("id").Value;
                            string userName;
                            Dictionary<string, string> extraData = GetExtraData(accessToken, document, out userName);
                            return new AuthenticationResult(
                                isSuccessful: true,
                                provider: ProviderName,
                                providerUserId: userId,
                                userName: userName,
                                extraData: extraData);
                        }
                    }
                }
                catch (Exception exception)
                {
                    return new AuthenticationResult(exception);
                }
            }
}

但它收到以下错误

  

异常详细信息：System.Net.WebException：返回远程服务器   错误：（401）未经授权。

     

来源错误：

     

第524行：public override void ExecuteResult（ControllerContext context）

     

第525行：{

     

第526行：OAuthWebSecurity.RequestAuthentication（Provider，ReturnUrl）;

     

第527行：}

而且我也不确定如何获得额外的数据（对于linkedin来说，它是？fields =）。任何帮助将不胜感激。

更新：授权正在运行。

我猜以下代码无效

const string profileRequestUrl =
                "https://api.twitter.com/1.1/statuses/show/:id";

            string accessToken = response.AccessToken;

            var profileEndpoint =
                new MessageReceivingEndpoint(profileRequestUrl, HttpDeliveryMethods.GetRequest);
            HttpWebRequest request =
                WebWorker.PrepareAuthorizedRequest(profileEndpoint, accessToken);
            request.Host = "api.twitter.com";
            try
            {
                using (WebResponse profileResponse = request.GetResponse())
                {
                    using (Stream responseStream = profileResponse.GetResponseStream())
                    {

非常感谢任何帮助。
