ios - Alamofire - 不接受 failureCallBack 中的错误

Question

我们正在使用 Alamofire pod。现在我面临 NSError 的问题。

当我们编写 error: responseObj.result.error 时，Swift 3 不接受这一点。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 : Error?) -> ()

func makePOSTRequest (service : String!, parameters : [String: AnyObject]? = nil,  responseCallBack : APIClientResponseCallBack!) {
    self.sendRequest(method: .post, service: service, parameters: parameters, responseCallBack: responseCallBack);
}

private func sendRequest (method: Alamofire.HTTPMethod, service : String!, parameters : [String: AnyObject]? = nil, responseCallBack : APIClientResponseCallBack!) {

    var headers : [String : String] = [String : String]()
    headers["Accept-Version"] = "1.0"
    var urlString = self.urlStringWithService(service: service)
    urlString = Constants.API_BASE_URL

    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)
    }
}

Answer 1

responseCallBack(responseObj.response?.statusCode, responseObj.result.value as AnyObject, responseObj.result.error)

这对我有用
