我写了类似的问题，并且得到了如何在iOS应用中使用网络服务器?"的答复.但我需要示例，因为获取示例如何工作更简单，例如，您可以帮我提供该示例吗?

如果我想/注册新用户，如何在服务器上实施请求，我将以JSON格式接收服务器的应答，并且需要在变量'data'中将其发送给POST?例如，服务器是 http://myserver.com:8080 .

how can I implement request on my server for exhample if I want /register new user and I will receive the server's answere in JSON and I need to send it it POST in variable 'data' ? For exhample server is http://myserver.com:8080.

{ 
 email:
 password:
}  //this is register form but  how named this field?

我将收到这样的答覆:

{
result:[OK|fail]
 message: [error if fail]
 data: [if OK]
}

推荐答案

所以，这里有我的寺庙要发送登录请求，我已经实现了AFNetworking(

So, here you have my temple to send Login req, I have implemented AFNetworking(https://github.com/AFNetworking/AFNetworking) and NSJSONSerialization for parsing Json response. It is hard to give you a sample code, but I think if you customize this piece of code everything should work fine.

        - (void)sentLoginReqWithLogin:(NSString *)email andPassword:(NSString *)pass {

            NSDictionary *params = @{@"email" : email,
                                     @"password" : pass
                                     };


            AFHTTPClient *httpClient = [[AFHTTPClient alloc] initWithBaseURL:[NSURL URLWithString:HOST_URL]];
            NSMutableURLRequest *request = [httpClient requestWithMethod:POST
                                                                    path:LOGIN_URL
                                                              parameters:params];


            AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request];
            [httpClient registerHTTPOperationClass:[AFHTTPRequestOperation class]];

            [operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {

                NSLog(@"Response: %@", [[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding]);
                NSDictionary *response = (NSDictionary*)[NSJSONSerialization JSONObjectWithData:operation.responseData options:kNilOptions error:nil];

    //HERE YOU HAVE A RESPONSE (your server answer)
            } failure:^(AFHTTPRequestOperation *operation, NSError *error) {         
                NSLog(@"Error: %@", error);      
            }];


            [operation start];

}
