需要幫助使用Alamofire解析JSON與Swift使用Alamofire

我試圖從Google新聞中檢索文章並使用Swift進行解析。我正在使用Alamofire。我知道什麼時候解析的基礎知識，但輸出看起來有點複雜，我不知道如何訪問「標題」值。任何幫助，將不勝感激。謝謝！需要幫助使用Alamofire解析JSON與Swift使用Alamofire

這裏是JSON輸出：


responseData =  { 
     cursor =   { 
      currentPageIndex = 0; 
      estimatedResultCount = 445755633;

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

我真的被這一點，因爲它看起來並不像我在網上看到的大多數例子混淆。

解析'results'東西到自定義對象。儘可能少地將數據保持爲JSON。 – Sulthan

從GitHub添加SwiftyJSON做以下

 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"] 
     } 
    }

謝謝！我玩了更多，最終得到了SwiftJSON並使用了你的方法。它現在很好用！ – JChung37

你的好友好友 –

使用Alamofire與SwiftyJSON插件叫做Alamofire-SwiftyJSON

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

由於@cem olcay以上使用Alamofire和SwiftyJSON提及。嘗試下面的代碼。但還沒有測試過。

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 
} 

     } 
}
