使用HttpWebRequest上传带有PUT的文件时出错

request.Method = "PUT";

request.ContentType = "application/octet-stream";
request.ContentLength = data.Length;

using (Stream requestStream = request.GetRequestStream())
{
    requestStream.Write(data, 0, data.Length);
}

using (HttpWebResponse response = (HttpWebResponse)request.GetResponse())
{
    if (response.StatusCode == HttpStatusCode.OK)
    {
        // 处理响应内容
    }
}
