Question

我试图从Google新闻中检索文章并使用Swift解析它。我使用的是Alamofire。我知道解析时的基本知识，但输出似乎很复杂，我不知道如何访问＆＃34;标题＆＃34;值。任何帮助，将不胜感激。谢谢！

以下是JSON输出：


responseData =     {
        cursor =         {
            currentPageIndex = 0;
            estimatedResultCount = 445755633;
            moreResultsUrl = "http://news.google.com/nwshp?oe=utf8&ie=utf8&source=uds&q=sports&hl=en&start=0";
            pages =             (
                                {
                    label = 1;
                    start = 0;
                },
                                {
                    label = 2;
                    start = 1;
                },
                                {
                    label = 3;
                    start = 2;
                },
                                {
                    label = 4;
                    start = 3;
                },
                                {
                    label = 5;
                    start = 4;
                },
                                {
                    label = 6;
                    start = 5;
                },
                                {
                    label = 7;
                    start = 6;
                },
                                {
                    label = 8;
                    start = 7;
                }
            );
        };
        results =         (
                        {

            }
        );
    };
    responseDetails = "";
    responseStatus = 200;
}

我真的对此感到困惑，因为它看起来不像我在网上看过的大多数例子。

Answer 1

将Alamofire与名为SwiftyJSON的Alamofire-SwiftyJSON插件一起使用

Alamofire.request(.GET, 
  urlString, 
  parameters: ["foo": "bar"])
.responseSwiftyJSON({ (request, response, json, error) in
  var cursor = json["cursor"]
  // do your stuff ..
})

Answer 2

如上所述@cem olcay使用Alamofire和SwiftyJSON。请尝试以下代码。但尚未经过测试。

func getData() {
Alamofire.request(.GET, "YOUR_URL_STRING")
         .responseJSON { response in


let json = JSON(data: response)
if let title = json[0]["relatedStories"][0]["title"].string {
  //Now you got your value
}

         }
}

Answer 3

从github添加SwiftyJSON并执行以下内容

     import SwiftyJSON

      func parseJson() {

        Alamofire.request(.POST, "urlString", parameters:   parameter, encoding: .JSON)
        .responseJSON { response in


            //Check Response

            if response.result.isFailure == true {
                return
            }

            let json = JSON(response.result.value!)

          let cursorEntity = json["Cursor"]
          let currentIndex = json["cursor"].currentPageIndex
          let pageEntity =  json["cursor"]["pages"]
          let resultsEntity = json["cursor"]["results"]
       }
    }

需要帮助使用Alamofire解析使用Swift的JSON
