C# 推特API，带图像的推特，错误代码324“；验证媒体ID失败。”；

我已经能够成功发布附加图像的状态更新。我正在使用C#/.NET和一个名为Hammock的REST框架。首先，我将图像上传到upload.twitter.com/1.1/media/upload.json，并获取媒体ID。然后，我使用media_id参数向api.twitter.com/1.1/statuses/update.json发出请求。这可以很好地工作，只是偶尔，对于较大的图像，Twitter会使用以下JSON响应我的状态更新请求：

{"errors":[{"code":324,"message":"The validation of media ids failed."}]}

我尝试在媒体上传和状态更新之间等待几分钟，但没有成功。我也在Twitter的开发者论坛上发表过文章，但我也在这里发表了文章，以防有人有过这样的经历和见解。我在Twitter的API文档中没有看到“324”，尤其是在这里：

以下是在Fiddler中看到的确切请求/响应（敏感值被xxxx'd out除外）：

这是图像太大的结果。我刚刚遇到了同样的问题，通过发送一个jpg版本（300KB）的大型png（1.2MB）解决了这个问题

声明的大小限制是3MB，但它们可能有某种特定于客户端的限制。

我几乎可以肯定我看到了这一点，因为图像超出了我应用程序的照片大小限制配置。但是为什么Twitter会对太大的图片返回HTTP 200和媒体id？还有一个每日媒体上传限制：“用户有一个单独的、已发布的每日媒体上传限制，独立于他们未发布的每日状态更新限制。”图片大小并不总是原因。我肯定看到过比3MB小得多的图像也出现了同样的问题。我感觉到图像的维度也在其中扮演了一个角色，但是仍然没有文档描述Twitter对图像的确切限制。
