swift - 使用 Swift 的 URL 请求

Question

我可以访问“字典”moviedb 示例:https://www.themoviedb.org/search/remote/multi?query=exterminador%20do%20futuro&language=en

我怎样才能从这个页面只捕捉电影的名字和海报到我的 Swift 项目中？

这是答案:)

import UIKit

class ViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()
        reload()
    }

    private func reload() {
        let requestUrl = "https://www.themoviedb.org/search/remote/multi?query=exterminador%20do%20futuro&language=en"

        let config = NSURLSessionConfiguration.defaultSessionConfiguration()
        let session = NSURLSession(configuration: config)
        let request = NSURLRequest(URL: NSURL(string: requestUrl)!)

        let task = session.dataTaskWithRequest(request, completionHandler: { (data, response, error) -> Void in
            if let error = error {
                println("###### error ######")
            }
            else {
                if let JSON = NSJSONSerialization.JSONObjectWithData(data,
                    options: .AllowFragments,
                    error: nil) as? [NSDictionary] {

                        for movie in JSON {
                            let name = movie["name"] as! String
                            let posterPath = movie["poster_path"] as! String

                            println(name)        // "Terminator Genisys"
                            println(posterPath)  // "/5JU9ytZJyR3zmClGmVm9q4Geqbd.jpg"
                        }
                }
            }
        })

        task.resume()
    }
}
