(Mono C#) REST File Streaming UploadDemonstrates how to stream the REST body from a file. This example demonstrates a REST upload to the Azure Cloud Storage service.
// 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 Azure Storage Blob Service bool bTls = true; int port = 443; bool bAutoReconnect = true; // In this example, the storage account name is "chilkat". bool success = rest.Connect("chilkat.blob.core.windows.net",port,bTls,bAutoReconnect); if (success != true) { Debug.WriteLine(rest.LastErrorText); return; } // Provide Azure Cloud credentials for the REST call. Chilkat.AuthAzureStorage azAuth = new Chilkat.AuthAzureStorage(); azAuth.AccessKey = "AZURE_ACCESS_KEY"; // The account name used here should match the 1st part of the domain passed in the call to Connect (above). azAuth.Account = "chilkat"; azAuth.Scheme = "SharedKey"; azAuth.Service = "Blob"; // This causes the "x-ms-version: 2021-08-06" header to be automatically added. azAuth.XMsVersion = "2021-08-06"; success = rest.SetAuthAzureStorage(azAuth); // Set some request headers. success = rest.AddHeader("x-ms-blob-content-disposition","attachment; filename=\"hamlet.xml\""); success = rest.AddHeader("x-ms-blob-type","BlockBlob"); success = rest.AddHeader("x-ms-meta-m1","v1"); success = rest.AddHeader("x-ms-meta-m2","v2"); // Note: The application does not need to explicitly set the following // headers: x-ms-date, Authorization, and Content-Length. These headers // are automatically set by Chilkat. Chilkat.Stream fileStream = new Chilkat.Stream(); fileStream.SourceFile = "qa_data/xml/hamlet.xml"; // Upload to the Azure Cloud Storage service. // The file is streamed, so the full file never has to completely reside in memory. // The file is uploaded to the container named "test". string responseStr = rest.FullRequestStream("PUT","/test/hamlet.xml",fileStream); if (rest.LastMethodSuccess != true) { Debug.WriteLine(rest.LastErrorText); return; } // When successful, the Azure Storage service will respond with a 201 response code, // with an empty body. Therefore, in the success condition, the responseStr is empty. if (rest.ResponseStatusCode == 201) { Debug.WriteLine("File uploaded."); } else { // Examine the request/response to see what happened. Debug.WriteLine("response status code = " + Convert.ToString(rest.ResponseStatusCode)); Debug.WriteLine("response status text = " + rest.ResponseStatusText); Debug.WriteLine("response header: " + rest.ResponseHeader); Debug.WriteLine("response body (if any): " + responseStr); Debug.WriteLine("---"); Debug.WriteLine("LastRequestStartLine: " + rest.LastRequestStartLine); Debug.WriteLine("LastRequestHeader: " + rest.LastRequestHeader); } |
