ALAMOFIRE：responseSerializationFailed（Alamofire.AFError.ResponseSerializationFailureReason.inputDataNilOrZeroLength）

我试图通过alamofire上传数据，包括images.But它返回

responseSerializationFailed（Alamofire.AFError.ResponseSerializationFailureReason.inputDataNilOrZeroLength）

– 我的代码是，

Alamofire.upload(multipartFormData: { (multipartFormData) in multipartFormData.append((userid?.data(using: String.Encoding.utf8))!, withName: "user_id") multipartFormData.append((self.addUserBtnTag?.description.data(using: String.Encoding.utf8))!, withName: "slot") }, to: urlString, method: .post, encodingCompletion: { (result) in switch result { case .success(let upload, _, _): upload.responseJSON { response in print(response.result) print("Response : ", response) if response.result.isSuccess { let JSON = response.result.value as? NSDictionary print("EditJSON : ", JSON!) } } case .failure(let encodingError): print(encodingError) } }) 

但实际上我通过alamofire传递了十多个参数。谢谢你提前

只需从responseJSON更改为responseJSON即可

 Alamofire.upload(multipartFormData: { (multipartFormData) in multipartFormData.append((userid?.data(using: String.Encoding.utf8))!, withName: "user_id") multipartFormData.append((self.addUserBtnTag?.description.data(using: String.Encoding.utf8))!, withName: "slot") }, to: urlString, method: .post, encodingCompletion: { (result) in switch result { case .success(let upload, _, _): upload.responseString { response in print(response.result) print("Response : ", response) if response.result.isSuccess { let JSON = response.result.value as? NSDictionary print("EditJSON : ", JSON!) } } case .failure(let encodingError): print(encodingError) } })

尝试使用带alamofire的参数上传图像

  Alamofire.upload(multipartFormData: { (multipartFormData) in let imageData: NSData? = UIImageJPEGRepresentation(image, 0.5) as NSData? if imageData != nil { multipartFormData.append(imageData! as Data, withName: strImageKey, fileName: "imagep.jpeg", mimeType: "imagep/jpeg") for (key, value) in dictParams { let data = "\(value)".data(using: .utf8) multipartFormData.append(data! as Data, withName: key) } } }, with: requestName,encodingCompletion: { encodingResult in switch encodingResult { case .success(let upload, _, _): upload.responseJSON { response in log.debug("Image(s) Uploaded successfully:\(response)") //Networking.handleApiResponse(response) } case .failure(let encodingError): log.debug("encodingError:\(encodingError)") // Networking.handleApiResponse(response) Util.showAlertWithMessage(msgSorry, title:"Error") } completionHandler!(encodingResult) } )
