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,但是我无法使用wp7将图片上传到Twitter?

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)
我已经从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
}
}
下面, photoName是所选图像的名称(“e.OriginalFileName”) photoStream是PhotoChooserTask的“e.ChosenPhoto”
并且.AddFile()的第四个参数应该小心(我在做这个示例时没有考虑其他格式,你必须小心你的应用程序)
我希望这会有所帮助!!

LINQ to Twitter支持WP7,并且有一个TweetWithMedia方法,其工作原理如下:
private void PostButton_Click(object sender, RoutedEventArgs e)
{
if (string.IsNullOrWhiteSpace(TweetTextBox.Text))
MessageBox.Show("Please enter text to tweet.");
ITwitterAuthorizer auth = SharedState.Authorizer;
if (auth == null || !auth.IsAuthorized)
{
NavigationService.Navigate(new Uri("/OAuth.xaml", UriKind.Relative));
}
else
{
var twitterCtx = new TwitterContext(auth);
var media = GetMedia();
twitterCtx.TweetWithMedia(
TweetTextBox.Text, false, StatusExtensions.NoCoordinate, StatusExtensions.NoCoordinate, null, false,
media,
updateResp => Dispatcher.BeginInvoke(() =>
{
HandleResponse(updateResp);
}));
}
}
