How can i upload a file with the alamofire Router? Struggling with it.

I upload an image using the following code. For a given file type, you should be able to adjust the multipartEncoding block accordingly.
let json: [String : Any] = ["key", "value"]
let image = UIImage(named: "Something")!
guard let imageData = UIImagePNGRepresentation(image) else {
// We couldn't convert the image into data :(
}
let multipartEncoding: (MultipartFormData) -> Void = { multipartFormData in
multipartFormData.append(imageData, withName: "image", fileName: "image.png", mimeType: "image/png")
}
let request = Router.uploadPicture(parameters: json) // This is just a plain POST
sessionManager.upload(
multipartFormData: multipartEncoding,
with: request,
encodingCompletion: { (encodingResult) in
switch encodingResult {
case .success(let request, _, _):
request.validate().responseJSON(completionHandler: { (dataResponse) in
if let error = dataResponse.result.error {
// Network request failed :(
}
// SUCCESS!
})
case .failure(_):
// Couldn't encode the image :(
}
})
This is assuming your Router looks something like this.
enum Router: URLRequestConvertible {
case uploadPicture(parameters: Parameters)
static var baseUrl = "https://website.com/"
var method: HTTPMethod {
switch self {
case .uploadPicture(_):
return .post
}
}
var path: String {
switch self {
case .uploadPicture(_):
return "api/upload-picture/"
}
}
// MARK: - URLRequestConvertible
func asURLRequest() throws -> URLRequest {
let url = try Router.baseUrl.asURL().appendingPathComponent(path)
var urlRequest = try URLRequest(url: url, method: method)
var encodedUrlRequest: URLRequest?
switch self {
case .uploadPicture(let parameters):
encodedUrlRequest = try? JSONEncoding.default.encode(urlRequest, with: parameters)
}
return encodedUrlRequest ?? urlRequest
}
}
