Question

我想从中国购物网站获取一些数据。但我无法找到一种编码我得到的数据的好方法。如果我使用NSNSUTF8StringEncoding，它会输出nil。如果使用NSASCIIStringEncoding，网站上的中文字符无法正确显示。有什么方法可以解决这个问题，还是应该使用像AFNetworking这样的第三个网络库？

以下是我的代码：

import UIKit

class ViewController: UIViewController {
  override func viewDidLoad()
{
    super.viewDidLoad()
    // Do any additional setup after loading the view, typically from a nib.

    let url = NSURL(string:"https://item.taobao.com/item.htm?id=45457007854")!


    let request = NSURLRequest(URL: url)

    let task = NSURLSession.sharedSession().dataTaskWithRequest(request, completionHandler: { (data, response, error) -> Void in
        if let urlContent=data{

            print(urlContent)

        let webContent = NSString(data: urlContent, encoding:NSASCIIStringEncoding)

        print(webContent)

        }

    })
    task.resume()




}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
    // Dispose of any resources that can be recreated.
}


}

部分结果如下所示

print(urlContent)
