在Object－C中AFNetworking几乎是我们不可或缺的第三方库，使用起来非常方便，在Swift中，Alamofire是对应AFNetworking的第三方库，使用方法完全一样，下面看看常用的GET和POST怎么来写的：
新的Alamofire对请求做了改动如下：

var urlString = "https://httpbin.org/get";

        Alamofire.request(urlString).responseJSON { response in
            print(response.request)  // original URL request
            print(response.response) // HTTP URL response
            print(response.data)     // server data
            print(response.result)   // result of response serialization

            if let JSON = response.result.value {
                print("JSON: \(JSON)")
            }
        }


        let parameters: Parameters = [
            "foo": [1,2,3],
            "bar": [
                "baz": "qux"
            ]
        ]
        let headers: HTTPHeaders = [
            "Authorization": "Basic QWxhZGRpbjpvcGVuIHNlc2FtZQ==",
            "Accept": "application/json"
        ]


        Alamofire.request(urlString, method: .get, parameters: parameters, encoding: URLEncoding.default, headers: headers).responseJSON { (respond) in
            if let JSON = respond.result.value {
                print("JSON: \(JSON)")
            }

        }

以上为新改动后常用方法

func loadData() {
        Alamofire.request(.GET, "https://api.108tian.com/mobile/v3/SceneDetail?id=528b91c9baf6773975578c5c", parameters: nil).responseJSON() { response in

            if let dic = response.result.value {
                print("dic: \(dic)")
            }
            else
            {
                print("dic: \(response)")
            }
        }



        var headers:Dictionary = [String:String]()
        headers["Content-Type"] = "application/json"
        headers["Set-Cookie"] = "xxxxxxxxxxxxxxxxx"


        var dic = [String:AnyObject]()
        dic["id"] = "CodingFire"
        dic["passWord"] = "1234567890"


        Alamofire.request(.POST, "https://api.108tian.com/mobile/v3/SceneDetail?id=", parameters:dic , encoding: ParameterEncoding.JSON, headers: headers).responseJSON{ (response)  in




            if let dic = response.result.value {
                print("dic: \(dic)")
            }
            else
            {
                print("dic: \(response)")
            }
        }
｝

这俩接口需要替换成你自己的，博主只是随便写下，亲测无误。
