我正在尝试使用Alamofire将一些文本数据和图像保存到服务器，但是出现以下错误：

I am trying to save some text data and an image to server using Alamofire but I am getting following error:

失败：responseSerializationFailed （Alamofire.AFError.ResponseSerializationFailureReason.jsonSerializationFailed（错误域= NSCocoaErrorDomain代码= 3840字符0周围的无效值。 UserInfo = {NSDebugDescription =字符0周围的无效值。}））

FAILURE: responseSerializationFailed(Alamofire.AFError.ResponseSerializationFailureReason.jsonSerializationFailed(Error Domain=NSCocoaErrorDomain Code=3840 "Invalid value around character 0." UserInfo={NSDebugDescription=Invalid value around character 0.}))

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) } }

推荐答案

iOS代码正确，后端代码存在问题。 json格式不正确。我更正了后端的json格式，它开始正常工作。

The iOS code is correct, there was problem in backend code. The json was not being properly formed. I corrected the json formation in backend and it started working fine.
