Vishal Darvara的解决方案有点清晰，可以回答Alamofire 5。

    func uploadPhoto(_ url: String, image: UIImage, params: [String : Any], header: [String:String], completion: @escaping (JSON) -> ()) {
    let httpHeaders = HTTPHeaders(header)
    lastRequest = AF.upload(multipartFormData: { multiPart in
        for p in params {
            multiPart.append("\(p.value)".data(using: String.Encoding.utf8)!, withName: p.key)
        }
       multiPart.append(image.jpegData(compressionQuality: 0.4)!, withName: "avatar", fileName: "file.jpg", mimeType: "image/jpg")
    }, to: url, method: .post, headers: httpHeaders) .uploadProgress(queue: .main, closure: { progress in
        print("Upload Progress: \(progress.fractionCompleted)")
    }).responseJSON(completionHandler: { data in
        print("upload finished: \(data)")
    }).response { (response) in
        switch response.result {
        case .success(let resut):
            print("upload success result: \(resut)")
        case .failure(let err):
            print("upload err: \(err)")
        }
    }
}
