SerializationFailure在使用Alamofire发布数据时发生错误

我试图使用Alamofire保存一些文本数据和图像到服务器，但我得到以下错误：

FAILURE：responseSerializationFailed（Alamofire.AFError.ResponseSerializationFailureReason.jsonSerializationFailed（Error Domain = NSCocoaErrorDomain Code = 3840“Invalid value around character。”UserInfo = {NSDebugDescription =字符0周围的值无效。

我的代码：

internal func postContent(forApi Name:String, image:UIImage?, withData payload:[String: String], success: ((_ response:[String: AnyObject])->Void)?, failure: ((Error)->Void)?) { //create Alamofire request //if everything was fine call success block with people array passed into it //if failure occurred, call failure block with error. if(isConnectedToNetwork()){ let url = SharedConstants.baseURL+Name print("url "+SharedConstants.baseURL+Name) Alamofire.upload(multipartFormData: { (multipartFormData) in if let img = image { multipartFormData.append(UIImageJPEGRepresentation(img, 0.5)!, withName: "photo_path", fileName: "swift_file.jpeg", mimeType: "image/jpeg") } for (key, value) in payload { multipartFormData.append(value.data(using: .utf8)!, withName: key) } }, to: url, method: .post , headers:nil, encodingCompletion: { (result) in switch result { case .success(let upload, _, _): upload.responseJSON(completionHandler: { (response) in print(response.request) // original URL request print(response.response) // URL response print(response.data) // server data print(response.result) // result of response serialization if let JSON = response.result.value { print(JSON) success!(JSON as! [String: AnyObject]) } else{ failure!(ErrorType.noRecordFound) } }) case .failure(let error): print(error) } }) } else{ failure!(ErrorType.internetNotWorking) } }

iOS代码是正确的，后端代码存在问题。 json的forms不正确。 我纠正了后端json的形成，并开始正常工作。
