(C#) Use an Azure Service SASShows how to use an Azure Service SAS. (In this case, it is an SAS for a blob.)
// Azure Blob Service Example: Upload binary bytes to a block blob. // This uses a Service SAS for Authorization. // 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; } // ---------------------------------------------------------------------------------------------- // The code above this comment could be placed inside a function/subroutine within the application // because the connection does not need to be made for every request. Once the connection is made // the app may send many requests.. // ---------------------------------------------------------------------------------------------- // Note: The application does not need to explicitly set the following // headers: Content-Length, x-ms-date, Authorization. These headers // are automatically set by Chilkat. // Let's load a previously computed Azure Storage Account SAS token and use it. // See How to Create an Azure Service SAS Chilkat.StringBuilder sbToken = new Chilkat.StringBuilder(); success = sbToken.LoadFile("qa_data/tokens/azureStorageServiceSas.txt","utf-8"); if (success != true) { Debug.WriteLine("Failed to load SAS token."); return; } // Add the Shared Access Signature query params for authorization. rest.AddQueryParams(sbToken.GetAsString()); // IMPORTANT: Make sure to set the x-ms-blob-type header: success = rest.AddHeader("x-ms-blob-type","BlockBlob"); // IMPORTANT: Make sure to add the x-ms-date header. // When the header name is "x-ms-date", Chilkat will recognize the keyword "NOW" // and will substitute the current system date/time formatted as required by Microsoft. success = rest.AddHeader("x-ms-date","NOW"); // For this example, we'll just load a JPG file into memory.. Chilkat.BinData binData = new Chilkat.BinData(); success = binData.LoadFile("qa_data/jpg/starfish.jpg"); if (success != true) { Debug.WriteLine("Failed to load JPG file."); return; } // Note: The maximum size of a block blob created by uploading in a single step is 64MB. // For larger files, the upload must be broken up into blocks. There is another Chilkat example for that.. Chilkat.StringBuilder sbResponse = new Chilkat.StringBuilder(); success = rest.FullRequestBd("PUT","/mycontainer/starfish.jpg",binData,sbResponse); if (success != true) { Debug.WriteLine(rest.LastErrorText); return; } // When successful, the Azure Storage service will respond with a 201 response status code, // with no response body. if (rest.ResponseStatusCode != 201) { // 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): " + sbResponse.GetAsString()); Debug.WriteLine("---"); Debug.WriteLine("LastRequestStartLine: " + rest.LastRequestStartLine); Debug.WriteLine("LastRequestHeader: " + rest.LastRequestHeader); Debug.WriteLine("Failed."); return; } Debug.WriteLine("Success."); |
