Question

我尝试在oracle云基础架构iaas上上传文件，但收到错误。我不确定正文中附加的文件是否在格式正确与否。 ApI签名是正确的，我只怀疑我编写的代码是否符合要求。该代码段如下所述。代码段：

            FileInfo f = new FileInfo(FileUpload1.FileName);
            byte[] filebyte =FileUpload1.FileBytes;

            var postdata = Encoding.UTF8.GetBytes(filebyte.ToString());
        Console.Write(postdata.Length);

            var tenancyId = ConfigurationManager.AppSettings["BMCTenancyId"];
            var userId = ConfigurationManager.AppSettings["BMCUserId"];
            var fingerprint = ConfigurationManager.AppSettings["BMCFingerprint"];
            var privateKeyPath = ConfigurationManager.AppSettings["BMCPrivateKeyPath"];
            var privateKeyPassphrase = ConfigurationManager.AppSettings["BMCPrivateKeyPassphrase"];

            var signer = new RequestSigner(tenancyId, userId, fingerprint, privateKeyPath, privateKeyPassphrase);

            ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;

            var uri = new Uri($"https://objectstorage.us-phoenix-1.oraclecloud.com/");

            var request = (HttpWebRequest)WebRequest.Create(uri);
            request.Method = "POST";
            request.Accept = "application/json";
            request.SendChunked = true;
            request.ContentType = "text/plain";

            request.ContentLength =postdata.Length;
        try
        {
            using (var stream = request.GetRequestStream())
            {
                stream.Write(postdata, 0, postdata.Length);
                stream.Close();
            }
        }
        catch(Exception ex)
        {
            Response.Write(ex.Message);

        }



            request.Headers["x-content-sha256"] = Convert.ToBase64String(SHA256.Create().ComputeHash(postdata));

            signer.SignRequest(request);

            Console.WriteLine($"Authorization header: {request.Headers["authorization"]}");

            ExecuteRequest(request);

            Console.WriteLine("The value of 'ContentLength' property after sending the data is {0}", request.ContentLength);
    }

        private static void ExecuteRequest(HttpWebRequest request)
        {
            try
            {
                var webResponse = (HttpWebResponse)request.GetResponse();
                var response = new StreamReader(webResponse.GetResponseStream()).ReadToEnd();
                Console.WriteLine($"Response: {response}");
            }
            catch (WebException e)
            {
                Console.WriteLine($"Exception occurred: {e.Message}");
                Console.WriteLine($"Response: {new StreamReader(e.Response.GetResponseStream()).ReadToEnd()}");
            }
        }

一方面，您需要将URL更新为以下格式：

var uri = new Uri($"https://objectstorage.us-phoenix-1.oraclecloud.com/n/{namespaceName}/b/{bucketName}/o/{objectName}");

文档：https://docs.cloud.oracle.com/iaas/api/#/en/objectstorage/20160918/Object/PutObject

此外，您能否编辑问题以包括收到的完整错误，这将有助于调试。

如果您设置ContentLength> 0或SendChunked == true，则必须提供请求正文。为此，请在[Begin] GetResponse之前调用[Begin] GetRequestStream
