Uploading streams

[ecoopnet]

I want to upload stream without creating NSData (like Alamofire/AFNetworking)
because uploading very large file(like long movie file) will cause crash by memory problem.

I tried to create custom RequestBodyBuilder but buildBodyFromObject return NSData...
Please tell me how to fix this problem on APIKit 1 or 2?

APIKit 2 supports both NSData and NSInputStream, but APIKit 1 supports NSData only.

On APIKit 2, RequestBodyBuilder enumeration is converted to BodyParametersType protocol, which returns RequestBodyEntity. Since RequestBodyEntity can represents NSInputStream, your custom body parameters can return NSInputStream.

public enum RequestBodyEntity {
    case Data(NSData)
    case InputStream(NSInputStream)
}

public protocol BodyParametersType {
    var contentType: String { get }
    func buildEntity() throws -> RequestBodyEntity
}

By the way, I will adopt NSInputStream in MultipartFormDataParameters in the future beta of APIKit 2.

Thats great!

I am just using multipart form data on APIKit 1.
So I'll try APIKit2 next time.

Thanks for your nice answer.

NSStream-based MultipartFormDataParameters is implemented in #160 and available in 2.0.0 beta 4!
