(Swift) Box.com Streaming Upload File

Demonstrates how to upload a file to box.com, streaming the file directly from the filesystem.

Note: This example requires a fix that is included in Chilkat v9.5.0.70 and above.

    //  First, make the initial connection.
    //  A single REST object, once connected, can be used for many Box REST API calls.
    //  The auto-reconnect indicates that if the already-established HTTPS connection is closed,
    //  then it will be automatically re-established as needed.
    var bAutoReconnect: Bool = true

    //  IMPORTANT: Note that the domain is "upload.box.com", not "api.box.com"

    //  The request body uses the "multipart/form-data" format to transmit two "parts".
    //  The first part is called "attributes" and contains a JSON object with information about the file, including the name of the file
    //  and the ID of the parent folder. The second part contains the contents of the file.
    //  (Note that the name of the second "part" is ignored.)

    rest.AddHeader("Content-Type", value: "multipart/form-data")

    //  Provide the content for each part of the request...

    //  First the JSON attributes.  Use "0" for the root folder.

    //  "application/octet-stream" can be safely used for any type file..
    rest.AddHeader("Content-Type", value: "application/octet-stream")

    //  IMPORTANT: This example requires Chilkat v9.5.0.70 or later, for a fix that was made in
    //  multipart/streaming uploads.
    let fileStream = CkoStream()
    fileStream.SourceFile = "qa_data/jpg/hedgehogs.jpg"
    rest.SetMultipartBodyStream(fileStream)

        print("Request header:")
        print("\(rest.LastRequestHeader)")
