多年来，我一直在我的网站上使用 twitter 登录。我今天随机决定测试它，发现它不起作用。

我正在使用 dotnetopenauth 3.4.7.11121 。我的网络配置中有 twitterConsumerKey 和 twitterConsumerSecret。关于首先在哪里进行故障排除的想法？

错误是“远程服务器返回错误：（401）未经授权。”

我的注释代码：

public static OutgoingWebResponse StartSignInWithTwitter(bool forceNewLogin)
    {
        var redirectParameters = new Dictionary<string, string>();
        if (forceNewLogin)
        {
            redirectParameters["force_login"] = "true";
        }
        Uri callback = MessagingUtilities.GetRequestUrlFromContext().StripQueryArgumentsWithPrefix("oauth_");
        var request = TwitterSignIn.PrepareRequestUserAuthorization(callback, null, redirectParameters);
        return TwitterSignIn.Channel.PrepareResponse(request);
    }

例外：

更新 我使用了提琴手，发现 dotnetopenauth 在从 http 重定向到 https 时没有转发身份验证。

我发现了我的问题。Twitter 似乎已经开始强制使用 https 并且重定向停止工作。我更新了我的 twitter 消费者，将其从 http 更改为 https。我的消费者是从样品中取出的。

        {
            RequestTokenEndpoint = new MessageReceivingEndpoint("https://twitter.com/oauth/request_token", HttpDeliveryMethods.GetRequest | HttpDeliveryMethods.AuthorizationHeaderRequest),
            UserAuthorizationEndpoint = new MessageReceivingEndpoint("https://twitter.com/oauth/authorize", HttpDeliveryMethods.GetRequest | HttpDeliveryMethods.AuthorizationHeaderRequest),
            AccessTokenEndpoint = new MessageReceivingEndpoint("https://twitter.com/oauth/access_token", HttpDeliveryMethods.GetRequest | HttpDeliveryMethods.AuthorizationHeaderRequest),
            TamperProtectionElements = new ITamperProtectionChannelBindingElement[] { new HmacSha1SigningBindingElement() },
        };

        public static readonly ServiceProviderDescription SignInWithTwitterServiceDescription = new ServiceProviderDescription
        {
            RequestTokenEndpoint = new MessageReceivingEndpoint("https://twitter.com/oauth/request_token", HttpDeliveryMethods.GetRequest | HttpDeliveryMethods.AuthorizationHeaderRequest),
            UserAuthorizationEndpoint = new MessageReceivingEndpoint("https://twitter.com/oauth/authenticate", HttpDeliveryMethods.GetRequest | HttpDeliveryMethods.AuthorizationHeaderRequest),
            AccessTokenEndpoint = new MessageReceivingEndpoint("https://twitter.com/oauth/access_token", HttpDeliveryMethods.GetRequest | HttpDeliveryMethods.AuthorizationHeaderRequest),
            TamperProtectionElements = new ITamperProtectionChannelBindingElement[] { new HmacSha1SigningBindingElement() },
        };

半相关：我的旧时间线 URL“ http://twitter.com/statuses/user_timeline/14529984.xml ”更改为https://api.twitter.com/1/statuses/user_timeline/14529984.xml在某些时候打破了另一个我的应用程序的功能。
