Windows Phone 7：如何将推文发布到Twitter

Question

目前，我正在从Windows Phone共享功能。

我的目的是从Windows Phone应用程序向Facebook和Twitter分享用户的状态。

我成功完成了Facebook共享，现在我试图将状态（仅120 Words tweet）共享给Twitter。

我使用this完成了Twitter帐户的身份验证。

当我尝试使用此tweet按钮单击事件登录到帐户后，将tweet发布到twitter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"

我已经成功地将我的应用程序注册到twitter开发人员帐户，并在进行此调用之前已收到访问令牌密钥。

通过分析您的代码，看来您必须在下面的代码块中进行更改：

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，祝您愉快。
