Need Help Parsing JSON with Swift using Alamofire

2019-08-12 12:52发布

I'm trying to retrieve an article from Google news and parse it using Swift. I'm using Alamofire. I know the basics of what to when parsing, but the output seems kind of complex and I don't know how to access the "title" value. Any help would be appreciated. Thanks!

Here is the JSON Output:


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;
}

I'm really confused by this because it doesn't look like most examples I've seen online.

Use Alamofire with SwiftyJSON plugin called Alamofire-SwiftyJSON

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

As @cem olcay mentioned above use the Alamofire and SwiftyJSON. Try the below code. But haven't tested.

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
}

         }
}

add SwiftyJSON from github and do the stuff below

     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"]
       }
    }
