Response data

I download pictures and save it on my server as data. Is there an easier way to get data from the response?
in the previous version there was a simple command for this, I don't understand why it was necessary to complicate everything response.http.body.data

`import Vapor

class PictureManager {

static func saveImage(req: Request, externalUrl: String, name: String) throws -> EventLoopFuture<String> {

    var urlString = externalUrl

    if !urlString.contains("http") {
        urlString = (baseUrl + externalUrl)
    }
    
    return req.client.get("\(urlString)").flatMap { (response) in

        guard var body = response.body, let data = body.readData(length: body.readableBytes) else {
            return req.eventLoop.makeFailedFuture(Abort(.badRequest))
        }
        
        let imageData = ImageData(name: name, data: data, id: UUID())
        return imageData.save(on: req.db).flatMap({ req.eventLoop.tryFuture({ try imageData.url() }) })
    }
}

}`

Start by reading the response.body usage in the supplied PictureManager example and compare it with the referenced response.http.body.data from the previous version. Determine which response-data access API is currently available and define the desired simpler usage; done means the intended response data can be accessed without the manual buffer handling shown.
