    func loadData() {
        let url = URL(string: "http://www.baidu.com")
        
        URLSession.shared.dataTask(with: url!) { (data, _, error) in
            guard let data = data else {
                print("网络请求失败 \(String(describing: error))")
                return
            }
            
            if let html = String(data: data, encoding: .utf8) {
                print(html)
            }
        }.resume()
    }
