将图像直接上传到twitter

Question

我需要帮助将图像直接上传到Windows Phone 7中的Twitter.

我完成了Twitter的oauth流程,也可以更新推文,但我无法使用wp7将图像上传到twitter？

Answer 1

我通过使用Hammock.WindowsPhone.Mango库为此制定了解决方案.(TweetSharp内部使用Hammock库来实现oAuth和其他功能,但我从未使用过TweetSharp或Twitterizer)

我从Nuget安装了最新版本的Hammock

然后使用以下代码将照片上传到Twitter:

public void uploadPhoto(Stream photoStream, string photoName)
{
var credentials = new OAuthCredentials
        {
            Type = OAuthType.ProtectedResource,
            SignatureMethod = OAuthSignatureMethod.HmacSha1,
            ParameterHandling = OAuthParameterHandling.HttpAuthorizationHeader,
            ConsumerKey = TwitterSettings.consumerKey,
            ConsumerSecret = TwitterSettings.consumerKeySecret,
            Token = TwitterSettings.accessToken,
            TokenSecret = TwitterSettings.accessTokenSecret,
            Version = "1.0a"
        };


        RestClient restClient = new RestClient
        {
            Authority = "https://upload.twitter.com",
            HasElevatedPermissions = true,
            Credentials = credentials,
            Method = WebMethod.Post
         };
         RestRequest restRequest = new RestRequest
         {
            Path = "1/statuses/update_with_media.json"
         };

         restRequest.AddParameter("status", tbxNewTweet.Text);
         restRequest.AddFile("media[]", photoName, photoStream, "image/jpg");

}

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


private void PostTweetRequestCallback(RestRequest request, Hammock.RestResponse response, object obj)
{
        if (response.StatusCode == System.Net.HttpStatusCode.OK)
        {
        //Success code
        }
}

这里,photoName是所选图像的名称("e.OriginalFileName")photoStream是PhotoChooserTask中的"e.ChosenPhoto"

并且应该注意.AddFile()的第4个参数(在执行此示例时我没有考虑其他格式,您必须小心处理您的应用程序)

我希望这有帮助!!
