Alamofire 4分段上传带标题

如何使用Alamofire v4上传我自己的标题？ 在v3的情况下，我为下面的代码创建了我自己的函数，但我不能用v4做同样的事情。

static func upload(method: Alamofire.Method, urlString: String, multipartFormData: (data: Alamofire.MultipartFormData) -> (), completionHandler: ( response: Response, statusCode:Int, json:JSON) -> ()){ Alamofire.upload(method, urlString, headers: MyRequest.makeHeaders(), multipartFormData: multipartFormData, encodingCompletion: { encodingResult in switch encodingResult { case .Success(let upload, _, _): upload.responseJSON { response in switch response.result { case .Failure: log.error("Upload request failed!!") case .Success: completionHandler(response: response, statusCode: (response.response?.statusCode)!, json:JSON(response.result.value!)) } } case .Failure(let error): log.warning((error as NSError).localizedDescription) } }) } 

我尝试使用以下代码，但它不起作用

 static func upload(_ method: Alamofire.HTTPMethod, urlString: String, multipartFormData: (Alamofire.MultipartFormData) -> Swift.Void, completionHandler: @escaping (_ response: NSDictionary, _ statusCode:Int, _ json:JSON) -> Void){ Alamofire.upload(multipartFormData: multipartFormData, to: urlString, method: method, headers: MyRequest.makeHeaders(), encodingCompletion: { encodingResult in switch encodingResult { case .success(let upload, _, _): upload.responseJSON { response in switch response.result { case .failure: log.error("Upload request failed!!") case .success: completionHandler(response: response, statusCode: (response.response?.statusCode)!, json:JSON(response.result.value!)) } } case .failure(let error): log.warning((error as NSError).localizedDescription) } }) }

试试以下代码：

 Alamofire.upload(multipartFormData:{ multipartFormData in multipartFormData.append(unicornImageURL, withName: "unicorn") multipartFormData.append(rainbowImageURL, withName: "rainbow")}, usingThreshold:UInt64.init(), to:"https://httpbin.org/post", method:.post, headers:["Authorization": "auth_token"], encodingCompletion: { encodingResult in switch encodingResult { case .success(let upload, _, _): upload.responseJSON { response in debugPrint(response) } case .failure(let encodingError): print(encodingError) } })
