创建一个playground

let url = URL(string: "https://icanhazdadjoke.com/")!
var urlRequest = URLRequest(url:url)
urlRequest.addValue("text/plain",forHTTPHeaderField: "Accept")
URLSession.shared.dataTask(with: urlRequest) { data, response, error in
if let data = data,
let httpResponse = response as? HTTPURLResponse, (200..<300) ~= httpResponse.statusCode,
let strData = String(bytes: data, encoding: .utf8)
        {
            print(strData)
} }.resume()
