Azure rest api put blob
Please consider the following code snippet. This should work for you.
void UploadBlobWithRestAPI() { string storageKey = "<your access key here>"; string storageAccount = "<your storage account name here>"; string containerName = "<your container name here>"; string blobName = "test.txt"; string method = "PUT"; string sampleContent = "This is sample text."; int contentLength = Encoding.UTF8.GetByteCount(sampleContent); string requestUri = $"https://{storageAccount}.blob.core.windows.net/{containerName}/{blobName}"; HttpWebRequest request = (HttpWebRequest)WebRequest.Create(requestUri); string now = DateTime.UtcNow.ToString("R"); request.Method = method; request.ContentType = "text/plain; charset=UTF-8"; request.ContentLength = contentLength; request.Headers.Add("x-ms-version", "2015-12-11"); request.Headers.Add("x-ms-date", now); request.Headers.Add("x-ms-blob-type", "BlockBlob"); request.Headers.Add("Authorization", AuthorizationHeader(method, now, request, storageAccount, storageKey, containerName, blobName)); using (Stream requestStream = request.GetRequestStream()) { requestStream.Write(Encoding.UTF8.GetBytes(sampleContent), 0, contentLength); } using (HttpWebResponse resp = (HttpWebResponse)request.GetResponse()) { MessageBox.Show(resp.StatusCode.ToString()); }}public string AuthorizationHeader(string method, string now, HttpWebRequest request, string storageAccount, string storageKey, string containerName, string blobName) { string headerResource = $"x-ms-blob-type:BlockBlob\nx-ms-date:{now}\nx-ms-version:2015-12-11"; string urlResource = $"/{storageAccount}/{containerName}/{blobName}"; string stringToSign = $"{method}\n\n\n{request.ContentLength}\n\n{request.ContentType}\n\n\n\n\n\n\n{headerResource}\n{urlResource}"; HMACSHA256 hmac = new HMACSHA256(Convert.FromBase64String(storageKey)); string signature = Convert.ToBase64String(hmac.ComputeHash(Encoding.UTF8.GetBytes(stringToSign))); String AuthorizationHeader = String.Format("{0} {1}:{2}", "SharedKey", storageAccount, signature); return AuthorizationHeader;}And the traffic captured by Fiddler as follows:
The solution above only uploads files up to 4MB in size. I had need of a PowerShell version for a project requirement and went down the wrong trail with the solution above. For a custom function to chunk a BLOB to Azure RBS, I modified Robin Shahan's version from Red Gate at https://www.red-gate.com/simple-talk/cloud/platform-as-a-service/azure-blob-storage-part-4-uploading-large-blobs/.
