将包含内容和元数据的文件上传到谷歌文档会返回400无效/错误请求

我正试图从HTML5文件对话框上传一个文件到我的谷歌文档帐户。

我正在使用Google文档列表API 3.0版本来处理此请求，以及此链接中的说明。

查询后，我从DocumentsListJSON中收集正确的可恢复创建链接URL，并将XML实体POST到该链接以获得位置网址。我得到了200 OK的回复和位置URL。

在设置了头之后，我向位置URL发出PUT请求以上传文件。出于这个问题的目的，该文件小于512kb，不需要分块。

提交这个PUT请求后，我收到了一个400错误请求（有时是400无效请求）响应，并且文件没有上传。

有趣的是，如果我省略Content-Range标头，我可以上传一个小文件，但文本文件以外的文件已损坏。

我已经对加载在内存中的文件和本地文件进行了二进制比较。看起来他们很匹配。

为了访问API，我在一个带有http://www.google.com/jsapi.

我使用gadgets.io.makeRequest获取、POST和PUT数据。考虑到我能够毫无问题地查询文档列表，我的授权头和令牌似乎是正确的。

我应该采取什么措施来解决这个问题？
