【问题描述】：

我正在尝试通过 alamofire 上传数据，包括图片。但它会返回

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。

【问题讨论】：

您的回复为空或无。尝试在邮递员中执行此操作。

它在邮递员中给出响应。**responseSerializationFailed(Alamofire.AFError.ResponseSerializationFailureReason.inputDataNilOrZeroLength)** bold 这是作为错误返回而不是作为响应。如果值nil 那么它必须将响应作为缺少的参数。

你也可以添加你的邮递员回复吗？

不要让 Postman 误导您。它发生在我身上一次。邮递员“非常好”，即使在***范围大括号之外存在不相关的文本，它也能够解析 json。例如。 blahblah "someProperty":"someValue" 可以在 Postman 上工作，但不能在 Alamofire 上工作。因此，请检查您的回复的原始文本，看看您是否获得了可解析的数据。

谢谢@SharadChauhan 和 ** AuRis** 从你的回答中可以清楚地看到 :)

【参考方案1】：

只需将responseJSON 更改为responseString

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)
            

        )

【参考方案2】：

尝试使用 alamofire 上传带有参数的图像

 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)
    
    )
