Question

我正在尝试调用将JSON数据传递给服务器的API。以下是我的代码

NSDictionary *dictParam = [[NSDictionary alloc] initWithObjectsAndKeys:@"ABC", @"username", @"abc@xyz.com", @"email", @"linkedin", @"social", nil];

if([NSJSONSerialization isValidJSONObject:dictParam]){
    NSError *error = nil;
    NSData *jsonData = [NSJSONSerialization dataWithJSONObject:dictParam options:0 error:&error];

    NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:url];
    [request addValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
    [request addValue:@"application/json" forHTTPHeaderField:@"Accept"];
    request.HTTPMethod = @"POST";
    request.HTTPBody = jsonData;


    NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];
    NSURLSession *session = [NSURLSession sessionWithConfiguration:configuration delegate:self delegateQueue:nil];
    NSURLSessionDataTask *task = [session dataTaskWithRequest:request completionHandler:^(NSData * _Nullable data, NSURLResponse * _Nullable response, NSError * _Nullable error) {
        if(error == nil){
            NSDictionary *dictResult = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableContainers error:&error];
            NSLog(@"Result after login : %@",dictResult);
            NSLog(@"String : %@", [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding]);
        }
        else{
            NSLog(@"Error in Login : %@",error);
        }
    }];
    [task resume];
}

但我的问题是，数据没有被传递。在服务器端，他们没有获得任何数据。我无法找到我错过的地方。

这是一个http连接。

任何帮助将不胜感激。提前致谢

使用NSUrlSession不传递数据
