objective-c - Objective C の Web サーバーへの POST

Question

私は、目標 c で Web サーバーに値を送信する方法に取り組んできました。

送信された電子メールに私の値が表示されないという事実を除いて、私は両方の端ですべてが機能していると思います。

これが私のコードです。誰かが私が間違っていることを指摘できれば、それは素晴らしいことです。

（dvalは表示されていないものです）

NSMutableString *mmessage = [[NSMutableString alloc]initWithString:@""];
    [mmessage appendString:[NSString stringWithFormat:@"<p><b>Drink Name:</b> %@</p>", dval]];


    NSMutableURLRequest *urlRequest = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:@"http://test.com/api/stuff/send"]];
    NSMutableDictionary *postInfo = [NSDictionary dictionaryWithObject:[NSDictionary dictionaryWithObjectsAndKeys:mmessage, @"message", nil] forKey:@"form"];

    NSError *e = nil;
    NSData *postData = [NSJSONSerialization dataWithJSONObject:postInfo options:0 error:&e ];

    __block int resp_code = 0;

    [urlRequest setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
    [urlRequest setHTTPMethod:@"POST"];
    [urlRequest setHTTPBody:postData];

    [NSURLConnection sendAsynchronousRequest:urlRequest
                 queue:[NSOperationQueue mainQueue]
                 completionHandler:^(NSURLResponse *response, NSData *data, NSError *error) {
                     NSHTTPURLResponse *httpResponse = (NSHTTPURLResponse*)response;
                     resp_code = httpResponse.statusCode;
                     if(resp_code == 200){

                         NSDictionary *jsonObjects = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableContainers error:nil];

                         if ([[jsonObjects objectForKey:@"status"] isEqualToString:@"success"]) {
                             UIAlertView *emailsuccess = [[UIAlertView alloc] initWithTitle:@"Email Successfully sent." message:nil delegate:self cancelButtonTitle:@"Ok" otherButtonTitles:nil];
                             [emailsuccess show];
                         }

                         else if ([[jsonObjects objectForKey:@"status"] isEqualToString:@"failed"]) {
                             UIAlertView *emailfailed = [[UIAlertView alloc] initWithTitle:@"Email Failed." message:[jsonObjects objectForKey:@"messages"] delegate:self cancelButtonTitle:@"Ok" otherButtonTitles:nil];
                             [emailfailed show];
                         }

                        else {
                             UIAlertView *emailfailed = [[UIAlertView alloc] initWithTitle:@"Email Response." message:[jsonObjects objectForKey:@"messages"] delegate:self cancelButtonTitle:@"Ok" otherButtonTitles:nil];
                             [emailfailed show];

                     }

                         }
                     }];
