Question

我正在使用Google文档列表API上传文件和元数据。

只要文件小于512KB，我就能完美地工作。在512KB之后，我必须以512KB的块发送它。在每个块之后，我得到一个回复的HTTP状态代码308，这是正确的。

然而，在我发出最终请求后，我仍然得到308响应，而不是我期望的201响应。以下是发送和接收的HTTP标头。也许其他人可以看到我所缺少的东西。

修改

如果我在最后一个PUT请求中发送内容范围，则以下是最后的标题。

Answer 1

您的上一个请求似乎没有发送Content-Range。我认为这是问题，但我不确定，因为我之前从未使用过这个API。我只是想了解我在HTTP规范中所知道的内容。
