Alamofire - 将错误从Swift 2转换为Swift 3

我正在将我的项目从Swift 2.3转换为Swift 3.0。我们正在使用Alamofire pod进行联网。现在我遇到了NSError的问题。Alamofire - 将错误从Swift 2转换为Swift 3

当我们写error: responseObj.result.error时，Swift 3不接受这个。帮我解决这个问题。

检查我的代码：

static func getDataFromAPI(parameters : [String : AnyObject], successCallBack : @escaping APISuccessCallBack, failureCallBack : @escaping APIFailureCallBack) { 

     client.makePOSTRequest(service: Constants.API_BASE_URL, parameters: parameters) { (statusCode, response, error) ->() in 
      if statusCode == MobomoAPIClient.HTTPStatusCode.Success { 
       successCallBack(response) 
      } 
      else { 

       failureCallBack(client.responseErrorMessage(statusCode: statusCode, response: response, error: error)) 
      } 
     } 
    } 


typealias APIClientResponseCallBack = (_ statusCode: Int?, _ response : AnyObject?, _ error : NSError?) ->() 

`self.alamoFireManager!.request(urlString, method: method, parameters: parameters, encoding: JSONEncoding.default, headers: headers) 
      .responseJSON { (responseObj) -> Void in 
       responseCallBack(statusCode: responseObj.response?.statusCode, response: responseObj.result.value as AnyObject, error: responseObj.result.error) 
     }`

你应该改变回调的NSError?到Error?和施放failureCallBack的错误Error。

typealias APIClientResponseCallBack = (_ statusCode: Int?, _ response : AnyObject?, _ error : Error?) ->()

failureCallBack(client.responseErrorMessage(statusCode: statusCode, response: response, error: error as Error))

在 failureCallBack任何变化（client.responseErrorMessage（的StatusCode：的StatusCode，响应：响应，错误：错误）），因为当我们在typealias APIClientResponseCallBack在随后发生改变错误failureCallBack错误：错误 –

无法使用类型为'（statusCode：Int？，响应：AnyObject？“，错误：错误？）的参数列表调用'responseCallBack'' 面临此问题 –
