无法将类型 'Response<AnyObject, NSError>' 的值转换为闭包结果类型 'NSDictionary'

Question

class AlamofireService {


static let alamofireService = AlamofireService()


private init() {

}

internal func makePostServiceRequest(url: String, parameters: AnyObject, completion: (inner: () throws -> NSDictionary) -> Void) -> Void{


    Alamofire.request(.POST, URL_BASE, parameters: [IOS_PARAMS : parameters], encoding:.JSON).validate()
        .responseJSON

        {
            response in switch response.result
            {
            case .Success(let JSON):
                print("Success with JSON: \(JSON)")


                let response = JSON as! NSDictionary
                print(response)

                completion(inner: { return response })



            case .Failure(let error):
                print("Request failed with error: \(error)")
                completion(inner: { throw error })

            }
    }
}



internal func makeGetServiceRequestTemplates(completion: (inner: () throws -> NSDictionary) -> Void) ->Void {

    Alamofire.request(.GET, URl_TEMPLATES).validate().responseJSON

        {
            response in switch response.result
            {
            case .Success(let JSON):
                print("Success with JSON: \(JSON)")



                if let array = JSON as? [Dictionary<String, AnyObject>] {

                    for var i=0; i < array.count; i++ {

                        let templates = Mapper<VQuizTemplateTo>().map(array[i])
                        print(templates)

                    }


                }
                completion(inner: { return response }) //error is on this line


            case .Failure(let error):
                print("Request failed with error: \(error)")
                completion(inner: { throw error })
            }

    }
}

两个相同的方法，第一个没有错误，第二个和我标记的一样。无法弄清楚出了什么问题，尤其是这个无意义的错误。你能告诉我我做错了什么吗？

Answer 1

您返回的 response 类型为 Response<AnyObject, NSError>，这就是您收到该错误的原因..

尝试返回这个 response.result.value as! NSDictionary

只需将 completion(inner: { return response }) 替换为

completion(inner: { return response.result.value as! NSDictionary })

无法将类型 'Response<AnyObject, NSError>' 的值转换为闭包结果类型 'NSDictionary'

Cannot convert value of type 'Response<AnyObject, NSError>' to closure result type 'NSDictionary'
