使用resumable-edit-media上传时出现内部服务器错误（HTTP 500）

Question

我尝试使用resumable-edit-media链接更新google驱动器中的文件：

PUT /feeds/upload/create-session/default/private/full/file%3A0B5KhdsbryVeGS2pkT1JFWVYtaE0 HTTP/1.1

到目前为止一切正常。然后我“放”到“位置：”

中的URI

PUT /feeds/upload/create-session/default/private/full/file%3A0B5KhdsbryVeGS2pkT1JFWVYtaE0?upload_id=AEnB2UphMFkkbKRTFSM3amKjCobgc4pZrN0asIVeEXCtYjkAj-1dnlLz3zHzXvhJoFzJEP0n7ULaboaIkzVJdmfjpXHnRI7NjQ HTTP/1.1

谁能知道出了什么问题？
