swift 使用 AFHTTPRequestOperationManager

  let url ="http://www.baidu.com"

       let params = ["lat":39.26, "lon":41.03, "cnt":0]

        let arr = ["","",""]

        var type="text/plain"

        var sets=NSSet()

        

      var manager =AFHTTPRequestOperationManager()

        manager.responseSerializer.acceptableContentTypes = sets.setByAddingObject(type)

        manager.requestSerializer =AFHTTPRequestSerializer()

        manager.responseSerializer =AFJSONResponseSerializer()

        manager.POST(url, parameters: params,  success: { (operation:AFHTTPRequestOperation!, responseObject:AnyObject!) in

            

            println("JSON: " + responseObject.description!)

        

        },

            failure: { (operation: AFHTTPRequestOperation!, error:NSError!) in
