Google文檔列表API 308恢復不完整

Question

我正在使用Google文檔列表API來上傳文件以及元數據。

只要文件小於512KB，我就可以正常工作。在512KB之後，我必須以512KB大小發送它。在每個塊後，我都會收到一個308的HTTP狀態碼，這是正確的。

但是，在我發出最終請求後，我仍然得到308響應，而不是我期望的201響應。以下是發送和接收的HTTP頭。也許其他人可以看到我缺少的東西。

Answer 1

看來您的最後一個請求沒有發送Content-Range。我認爲這是問題，但不確定，因爲我以前從未使用過此API。我只是將我在HTTP規範中知道的內容脫掉。
