“我正在尝试将视频文件上传到指定的twit图片url，这有助于用户将他们的视频上传到twitter上。”当我按下按钮时，视频文件应该上传到我使用的url中。但是当我检查的时候，得到的回应是你请求的页面不能是found.Has任何人试图上传视频到傻瓜图。请提前给我一些codes.Thanks的样品。

错误与不正确的urlString有关。我也不知道你使用的是哪个twitpic-api版本。

twitpic-api-version-2 (需要使用的是最新的api-版本)需要先通过OAuth进行授权，api-key，消息和媒体作为参数

urlString应该是这样的：http://api.twitpic.com/2/upload.xml

twitpic-api-version-1 (不是最新的:只有一个，因为兼容性。将在将来某个时候关闭)需要您添加的参数，但也需要两个额外的oauth参数，这两个参数在您的身体中缺失。urlString应该是这样的：http://api.twitpic.com/1/upload.xml
