(Swift 2) Azure Storage: Upload Binary Data to Block Blob using BinData

Sample code to upload binary bytes (contained in a Chilkat BinData object) to a block blob in Azure Cloud Storage. This creates the block blob, or replaces an existing block blob.

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..

    // Azure Blob Service Example: Upload binary bytes to a block blob.
    // This creates a new block blob or replaces an existing one in its entirety.

    // This example requires the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    let rest = CkoRest()

    // Connect to the Azure Storage Blob Service
    var bTls: Bool = true
    var port: Int = 443
    var bAutoReconnect: Bool = true
    // In this example, the storage account name is "chilkat".
    var success: Bool = rest.Connect("chilkat.blob.core.windows.net", port: port, tls: bTls, autoReconnect: bAutoReconnect)
    if success != true {
        print("\(rest.LastErrorText)")
        return
    }

    // Provide Azure Cloud credentials for the REST call.
    let azAuth = CkoAuthAzureStorage()
    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: 2020-08-04" header to be automatically added.
    azAuth.XMsVersion = "2020-08-04"
    success = rest.SetAuthAzureStorage(azAuth)

    // 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.

    // IMPORTANT: Make sure to set the x-ms-blob-type header:
    success = rest.AddHeader("x-ms-blob-type", value: "BlockBlob")

    // For this example, we'll just load a JPG file into memory..
    let bd = CkoBinData()
    success = bd.LoadFile("qa_data/jpg/starfish.jpg")
    if success == false {
        print("Failed to load the file to be uploaded.")
        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..
    let sbResponseBody = CkoStringBuilder()
    success = rest.FullRequestBd("PUT", uriPath: "/mycontainer/starfish.jpg", binData: bd, responseBody: sbResponseBody)
    if success == false {
        print("\(rest.LastErrorText)")
        return
    }

    // When successful, the Azure Storage service will respond with a 201 response status code,
    // with no response body.

    if rest.ResponseStatusCode.intValue != 201 {
        // Examine the request/response to see what happened.
        print("response status code = \(rest.ResponseStatusCode.intValue)")
        print("response status text = \(rest.ResponseStatusText)")
        print("response header: \(rest.ResponseHeader)")
        print("response body (if any): \(sbResponseBody.GetAsString())")
        print("---")
        print("LastRequestStartLine: \(rest.LastRequestStartLine)")
        print("LastRequestHeader: \(rest.LastRequestHeader)")
        return
    }

    print("Success.")
