`我正在尝试将视频文件上传到twit pic的指定网址，这有助于用户将他们的视频上传到Twitter。当我按下按钮视频文件应上传到我使用的网址。但当我检查时，得到一个回复，你找不到你要求的页面。有人试图上传视频到twit pic。请给我一些示例代码。谢谢。

Answer 1

错误与错误的urlString有关。我也没看到你正在使用哪种twitpic-api版本。

twitpic-api-version-2（最新的api-version 应该使用）需要首先通过OAuth和api-key，消息和媒体作为参数进行授权 urlString应如下所示：http://api.twitpic.com/2/upload.xml

twitpic-api-version-1（不是最新的一个：只有那里因为兼容性。将来某个时候会关闭）需要你添加的参数，还需要两个额外的oauth参数，这些参数在你体内缺失。 urlString应如下所示：http://api.twitpic.com/1/upload.xml

将视频上传到twitpic
