(.NET Core C#) Amazon Glacier Upload Archive from In-Memory DataDemonstrates how to add an archive to a vault from data in memory. Note: This example requires Chilkat v9.5.0.78 or greater.
// This example requires the Chilkat API to have been previously unlocked. // See Global Unlock Sample for sample code. Chilkat.Rest rest = new Chilkat.Rest(); // Connect to the Amazon AWS REST server in the desired region. bool bTls = true; int port = 443; bool bAutoReconnect = true; bool success = rest.Connect("glacier.us-west-2.amazonaws.com",port,bTls,bAutoReconnect); // Provide AWS credentials. Chilkat.AuthAws authAws = new Chilkat.AuthAws(); authAws.AccessKey = "AWS_ACCESS_KEY"; authAws.SecretKey = "AWS_SECRET_KEY"; authAws.ServiceName = "glacier"; authAws.Region = "us-west-2"; success = rest.SetAuthAws(authAws); // -------------------------------------------------------------------------- // Note: The above REST connection and setup of the AWS credentials // can be done once. After connecting, any number of REST calls can be made. // The "auto reconnect" property passed to rest.Connect indicates that if // the connection is lost, a REST method call will automatically reconnect // if needed. // -------------------------------------------------------------------------- // Load the data to be uploaded. Chilkat.BinData bd = new Chilkat.BinData(); success = bd.LoadFile("qa_data/jpg/penguins.jpg"); // (The point here is that the contents of the bd don't necessarily have to come from a file.) // // For more information, see Glacier Upload Archive Reference Documentation // rest.AddHeader("x-amz-glacier-version","2012-06-01"); // We'll need to pre-compute the SHA256 tree hash and the SHA256 linear hash. // The hashes are added in the following request headers: // x-amz-sha256-tree-hash: SHA256 tree hash // x-amz-content-sha256: SHA256 linear hash Chilkat.Crypt2 crypt = new Chilkat.Crypt2(); crypt.HashAlgorithm = "sha256-tree-hash"; crypt.EncodingMode = "hexlower"; string treeHashHex = crypt.HashBdENC(bd); rest.AddHeader("x-amz-sha256-tree-hash",treeHashHex); crypt.HashAlgorithm = "sha256"; string linearHashHex = crypt.HashBdENC(bd); authAws.PrecomputedSha256 = linearHashHex; // We can optionally add a description rest.AddHeader("x-amz-archive-description","Penguins JPG"); Chilkat.StringBuilder sbResponseBody = new Chilkat.StringBuilder(); success = rest.FullRequestBd("POST","/AWS_ACCOUNT_ID/vaults/chilkat/archives",bd,sbResponseBody); if (success != true) { Debug.WriteLine(rest.LastErrorText); return; } int respStatusCode = rest.ResponseStatusCode; if (respStatusCode >= 400) { Debug.WriteLine("Response Status Code = " + Convert.ToString(respStatusCode)); Debug.WriteLine("Response Header:"); Debug.WriteLine(rest.ResponseHeader); Debug.WriteLine("Response Body:"); Debug.WriteLine(sbResponseBody.GetAsString()); return; } // Success is indicated by a 201 response status with an empty response body.
