可以使用分片上传来绕过此问题。以下是使用C#的示例代码：

var chunkSize = 5 * 1024 * 1024; // 5MB
var fileStream = new FileStream(filePath, FileMode.Open, FileAccess.Read);

var sessionId = "";

// Step 1: Initialize the upload session
var initSessionReq = new RestRequest(Method.POST);
initSessionReq.Resource = "/oss/v2/buckets/{bucketKey}/objects/{objectKey}/resumable";
initSessionReq.AddParameter("bucketKey", bucketKey, ParameterType.UrlSegment);
initSessionReq.AddParameter("objectKey", objectKey, ParameterType.UrlSegment);
initSessionReq.AddHeader("Content-Type", "application/json");
initSessionReq.AddHeader("Content-Length", fileStream.Length.ToString());
initSessionReq.AddHeader("x-upload-content-type", "application/octet-stream");
initSessionReq.AddHeader("x-upload-content-length", fileStream.Length.ToString());

var initSessionRes = client.Execute(initSessionReq);

if (initSessionRes.StatusCode == HttpStatusCode.Created)
{
    sessionId = JsonConvert.DeserializeObject(initSessionRes.Content).sessionId.Value;
}
else
{
    throw new Exception("Failed to initiate resumable upload session");
}

// Step 2: Upload the file chunks
var chunkCount = (int)Math.Ceiling((double)fileStream.Length / chunkSize);

for (int i = 0; i < chunkCount; i++)
{
    var start = i * chunkSize;
    var end = Math.Min(start + chunkSize, fileStream.Length);

    var fileChunk = new byte[chunkSize];
    fileStream.Read(fileChunk, 0, fileChunk.Length);

    var uploadReq = new RestRequest(Method.PUT);
    uploadReq.Resource = "/oss/v2/buckets/{bucketKey}/objects/{objectKey}/resumable/{sessionId}";
    uploadReq.AddParameter("bucketKey", bucketKey, ParameterType.UrlSegment);
    uploadReq.AddParameter("objectKey", objectKey, ParameterType.UrlSegment);
    uploadReq.AddParameter("sessionId", sessionId, ParameterType.UrlSegment);
    uploadReq.AddHeader("Content-Length", (end - start).ToString());
    uploadReq.AddHeader("Content-Range", $"{start}-{end - 1}/{file
