[manager POST:User_login_url parameters:dic success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {
            NSError *errorForJSON = [NSError errorWithDomain:@"请求数据解析为json格式，发出错误" code:2014 userInfo:@{@"请求数据json解析错误": @"中文",@"serial the data to json error":@"English"}];
            NSLog(@"responseObject is %@", responseObject);
        NSLog(@"the responseObject class is %@", [responseObject class]);
        NSDictionary *responsedic = [NSJSONSerialization JSONObjectWithData:responseObject options:NSJSONReadingMutableContainers error:nil];
        
        NSHTTPURLResponse *urlResponse = (NSHTTPURLResponse *)task.response;
        NSLog(@"the response state code is %ld", (long)urlResponse.statusCode);
        
        NSLog(@"the responseDic is %@", responsedic);
        
//        task.response
        
        } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
            NSLog(@"the task is %@", task);
            
            NSHTTPURLResponse *urlResponse = (NSHTTPURLResponse *)task.response;
            NSLog(@"the response state code is %ld", (long)urlResponse.statusCode);
            
            NSLog(@"error is %@", error.description);
