upload request

[kolisko]

Hi,

I would like to ask you if is possible to add upload request synchronous please?

Alamofire.upload(data, to: url)

Thank you,
Michal

Already supports that if you use Alamofire 4.0/AlamofireSynchronous 4.0

let response = Alamofire.upload(data, to: url).responseJSON();

Maybe @kolisko was asking about the multipart form data ? I did not find a better way than to add a new function using the same method you did :

class AlamofireSynchronous {
    class func uploadRequest(multipartFormData: @escaping (MultipartFormData) -> Void, to: URLConvertible, method: HTTPMethod, headers: HTTPHeaders? = nil) -> UploadRequest? {

        let semaphore = DispatchSemaphore(value: 0)
        var result: UploadRequest? = nil

        Alamofire.upload(multipartFormData: multipartFormData, to: to, method: method, headers: headers) { (res: Alamofire.SessionManager.MultipartFormDataEncodingResult) in

            switch res {
            case .success(let upload, _, _):
                result = upload
            case .failure(let e):
                log.error("Error while creating upload request : \(e)")
            }

            semaphore.signal()
        }
        
        _ = semaphore.wait(timeout: DispatchTime.distantFuture)
        return result
    }
}

this allows to call the following :

if let req = AlamofireSynchronous.uploadRequest(multipartFormData: { (multipartFormData: MultipartFormData) in
        //TODO: append your form data
    }, to: "http://www.upload.com", method: .post) {
        let res = req.responseJSON()
        //TODO: use your res
}

If this is not what @kolisko asked for, I'm ok with bringing this to a new issue. I'd like to make a PR about this, but do you see a better way to make this fit the actual project, instead of creating a new class ?

I would love to see multipartFormData added without adding the separate class.

@cheizer if you have any idea how to, I'm open to suggestions :)

I'm looking in to it, I have a temporary solution based on the code you posted for @kolisko. The problem I had with it was the semaphore was not working 100% of the time at least not in the debugger using Xcode 8.2.1. It's like the semaphore.wait was being ignored so the result was always nil.

Ok, I know this is late, but @cheizer, you also had that semaphore issue? I'm experiencing that on Xc 8.3 and I thought I was doing something inexplicably dumb.

Any updates?

[cheizer]

No, I've moved on, I still have the issue.
