如何在 iOS 应用程序中使用 Web 服务器？样品[关闭]

Question

我写了类似的问题，我得到了关于“如何将 Web 服务器与 iOS 应用程序一起使用？”的答案。但我需要样本，因为对我来说有一些样本是如何工作的更简单，例如，你能帮我处理那个样本吗：

如果我想要 /register 新用户，我如何在我的服务器上实现请求，我将收到服务器的 JSON 应答，我需要将它发送到变量 'data' 中的 POST ？例如服务器是http://myserver.com:8080。

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

我会收到这样的答复：

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

我需要示例如何发送和接收 /register 请求。对不起我的英语，它会更好:)

更新我也无法理解如何在 Objective-C 中使用这种形式？

Answer 1

所以，在这里你有我的寺庙来发送登录请求，我已经实现了 AFNetworking(https://github.com/AFNetworking/AFNetworking) 和 NSJSONSerialization 来解析 Json 响应。很难给你一个示例代码，但我认为如果你自定义这段代码，一切都应该可以正常工作。

        - (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];

}

Answer 2

// Post data to server
NSURL * url = [NSURL URLWithString:@"http://myserver.com/register/"]];

NSMutableURLRequest * request = [[NSMutableURLRequest alloc] initWithURL:url];
[request setHTTPMethod:@"POST"];
NSString * bodyString = [NSString stringWithFormat:@"&username=%@&password=%ld", "username", "password"];
[request setHTTPBody:[bodyString dataUsingEncoding:NSASCIIStringEncoding]];

NSURLConnection * urlConnection = [[NSURLConnection alloc] initWithRequest:request delegate:self startImmediately:YES];


// On server, do this (assuming PHP)
$username = $_REQUEST['username'];
$password = $_REQUEST['password'];

// Do w/e checks you need to do against the username and password, be sure to hash and salt the password
// Store user information in database
