swift - 使用 Alamofire 和 PromiseKit 使用 Swift 时出现 Void 错误（请求）

Question

在我的最后一个项目中，我一直在使用 alamofire 和 promisekit 连接到我的 Web 服务现在我有两者的新版本，当我创建请求时出现此错误

Cannot convert value of type 'DataRequest' to closure result type 'Void'

当我尝试这样做时会发生这种情况：

func CallOne() -> Promise<[String: AnyObject]>{
        return Promise{
            fullfil,reject -> Void in
            return Alamofire.request(
                url_api,
                method: .get).responseJSON{
                    response in
                    switch(response.result){
                    case .success(let res):
                        let data = res as? [String: AnyObject]
                        fullfil(data!)
                    case .failure(let error):
                        reject(error)
                    }
            }
        }
    }

当我尝试使用它时：

func CallTwo(email: String, phone: String) -> Promise<[String: AnyObject]>{
    let params =
        ["email": email, "phone": phone]
    return Promise{
        fullfil,reject -> Void in
        return Alamofire.upload(
            multipartFormData: { MultipartFormData in
                for (key, value) in params {
                    MultipartFormData.append(value.data(using: String.Encoding.utf8)!, withName: key)
                }
        }, to: url_api, method: .post) { (result) in
            switch (result){
            case .success(let upload, _, _):
                upload.responseJSON { response in
                    switch(response.result){
                    case .success(let res):
                        let data = res as? [String: AnyObject]
                        fullfil(data!)
                    case .failure(let error):
                        reject(error)
                    }
                }
            case .failure(let encodingError):
                print(encodingError)
            }
        }
    }
}

我收到这个错误Unable to infer closure type in the current context

我该如何解决？提前致谢
