ios - 如何在 Swift 中解析来自 Alamofire API 的 JSON 响应？

Question

按照我编写的代码，我也收到了 JSON 格式的响应，但 JSON 的类型是“AnyObject”，我无法将其转换为 Array 以便我可以使用它。

Alamofire.request(.POST, "MY URL", parameters:parameters, encoding: .JSON) .responseJSON
{
    (request, response, JSON, error) in

    println(JSON?)
}

Swift 2.0 Alamofire 3.0 的答案实际上应该更像这样:

Alamofire.request(.POST, url, parameters: parameters, encoding:.JSON).responseJSON
{ response in switch response.result {
                case .Success(let JSON):
                    print("Success with JSON: \(JSON)")

                    let response = JSON as! NSDictionary

                    //example if there is an id
                    let userId = response.objectForKey("id")!

                case .Failure(let error):
                    print("Request failed with error: \(error)")
                }
    }

Alamofire 4.0 和 Swift 3.0 更新:

Alamofire.request(url, method: .post, parameters: parameters, encoding: JSONEncoding.default)
            .responseJSON { response in
                print(response)
//to get status code
                if let status = response.response?.statusCode {
                    switch(status){
                    case 201:
                        print("example success")
                    default:
                        print("error with response status: \(status)")
                    }
                }
//to get JSON return value
            if let result = response.result.value {
                let JSON = result as! NSDictionary
                print(JSON)
            }

        }
