如何从我的服务器获取响应，以及如何访问该数据

Question

我没有从服务器端收到响应。以下是我的代码。什么样的错误请提前告诉我谢谢。

检查我的代码：

//NSString *jsonRequest = [NSString stringWithFormat:@"{\"Email\":\"%@\",\"FirstName\":\"%@\"}",user,fname];
NSLog(@"Request: %@", jsonRequest);

NSURL *url = [NSURL URLWithString:@"http://golf.42point5.com/API/Jsonapi.php?method=singup"];

NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:url];
NSData *requestData = [NSData dataWithBytes:[jsonRequest UTF8String] length:[jsonRequest length]];

[request setHTTPMethod:@"POST"];
[request setValue:@"application/json" forHTTPHeaderField:@"Accept"];
[request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
[request setValue:[NSString stringWithFormat:@"%d", [requestData length]] forHTTPHeaderField:@"Content-Length"];
[request setHTTPBody: requestData];

//NSURLConnection *connection = [NSURLConnection connectionWithRequest:request delegate:self];
NSURLSessionConfiguration *defaultConfigObject = [NSURLSessionConfiguration defaultSessionConfiguration];
    NSURLSession *defaultSession = [NSURLSession sessionWithConfiguration: defaultConfigObject delegate: nil delegateQueue: [NSOperationQueue mainQueue]];
    NSURLSessionDataTask * dataTask =[defaultSession dataTaskWithRequest:request
                                                       completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
                                                          NSLog(@"Response:%@ %@\n", response, error);
                                                           if(error == nil)
                                                          {

                                                              NSString * text = [[NSString alloc] initWithData:data encoding: NSUTF8StringEncoding];
                                                                              NSLog(@"Data = %@",text);
                                                                          }

                                                      }];
    [dataTask resume];
