Windows Phone 7：如何在 Twitter 上发布推文

Question

目前我正在开发 Windows Phone 的共享功能。

我的目的是通过我的 windows phone 应用程序将用户的状态分享到 Facebook 和 Twitter。

我已成功完成 Facebook 分享，现在我正在尝试将状态（仅限 120 字推文）分享到 twitter。

我使用 this 完成了 Twitter 帐户的身份验证。

当我使用此推文按钮单击事件登录帐户后尝试将推文发布到推特帐户时，

 private void btnPostTweet_Click(object sender, RoutedEventArgs e)
    {
        var credentials = new OAuthCredentials
        {
            Type = OAuthType.ProtectedResource,
            SignatureMethod = OAuthSignatureMethod.HmacSha1,
            ParameterHandling = OAuthParameterHandling.HttpAuthorizationHeader,
            ConsumerKey = AppSettings.consumerKey,
            ConsumerSecret = AppSettings.consumerKeySecret,
            Token = this.accessToken,
            TokenSecret = this.accessTokenSecret,
            Version = "1.1"
        };

        var restClient = new RestClient
        {
            Authority = "https://api.twitter.com",
            HasElevatedPermissions = true
        };

        var restRequest = new RestRequest
        {
            Credentials = credentials,
            Path = "/1.1/statuses/update.json",
            Method = WebMethod.Post
        };

  restRequest.AddParameter("status", Uri.EscapeDataString(txtTweetContent.Text));

        restClient.BeginRequest(restRequest, new RestCallback(PostTweetRequestCallback));
 }

在回调中，

private void PostTweetRequestCallback(RestRequest request, RestResponse response, object obj)
    {
        string str = response.ToString();
        Deployment.Current.Dispatcher.BeginInvoke(() =>
        {
            if (response.StatusCode == HttpStatusCode.OK)
            {
                MessageBox.Show(AppSettings.TWEET_POSTED_SUCCESSFULLY);
            }
            else if (response.StatusCode == HttpStatusCode.Forbidden)
            {
                MessageBox.Show(AppSettings.TWEET_POST_ERR_UPDATE_LIMIT);
            }
            else
            {
                MessageBox.Show(AppSettings.TWEET_POST_ERR_FAILED);
            }
            txtTweetContent.Text = "";
        });
    }

它给了我错误

"Bad Authentication data", Code="215"

我已成功将我的应用程序注册到 twitter 开发者帐户并在进行此调用之前收到了访问令牌密钥。

从分析您的代码看来，您必须在以下代码块处进行更改：

var credentials = new OAuthCredentials
    {
        Type = OAuthType.ProtectedResource,
        SignatureMethod = OAuthSignatureMethod.HmacSha1,
        ParameterHandling = OAuthParameterHandling.HttpAuthorizationHeader,
        ConsumerKey = AppSettings.consumerKey,
        ConsumerSecret = AppSettings.consumerKeySecret,
        Token = this.accessToken,
        TokenSecret = this.accessTokenSecret,
        Version = "1.1"
    };

改变这个：

 Version = "1.1" to Version="1.0"

现在您的代码将顺利运行，享受这一天。
