有没有人有解决方案？

给出这个的代码是：

let task = session.dataTask(with: request) {
        (
        data, response, error) in

        guard let _:Data = data, let _:URLResponse = response  , error == nil else {
            print(data)
            print("error")
            return
        }

        _ = NSString(data: data!, encoding: String.Encoding.utf8)

        //print(dataString)
    }

推荐答案

尝试类似这样的事情

 guard let requestUrl = URL(string:yourUrlString) else { return }
 let request = URLRequest(url:requestUrl)
 let task = session.dataTask(with: request) {
    (data, response, error) in
    if error == nil {
        //JSONSerialization
    }
 }
