编译器要
URLRequest和
Error
... var request = URLRequest(url: storeURL!) request.httpMethod = "Post" ... let task = session.dataTask(with: request, completionHandler: { (responsedata:Data?, response:URLResponse?, error:Error?) -> Void in我建议省略所有类型注释
let task = session.dataTask(with: request, completionHandler: { (responseData, response, error) -> Void in
