iPhone 프로그래밍 포스트 데이터

Question

iPhone에서 PHP 웹 서버로 데이터를 게시하려고합니다. 다음은 다음 코드입니다.

NSString * fname = @"Brain.";
 NSString * location = @"Germany";

 NSString *post =[NSString stringWithFormat:@"fname=Test&location=Germany"];

 NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];

 NSString *postLength = [NSString stringWithFormat:@"%d", [postData length]];

 NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];
 [request setURL:[NSURL URLWithString:@"http://frisbee.brianpagan.net/upload.php"]];
 [request setHTTPMethod:@"POST"];
 [request setValue:postLength forHTTPHeaderField:@"Content-Length"];
 [request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];
 [request setHTTPBody:postData];

 NSError *error;
 NSURLResponse *response;
 NSData *urlData=[NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
 NSString *data=[[NSString alloc]initWithData:urlData encoding:NSUTF8StringEncoding];
 NSLog(data);


    NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];
    int retVal = UIApplicationMain(argc, argv, nil, nil);
    [pool release];
    return retVal;
}

<body>
Welcome Test!<br />
Your location is  Germany .
</body>

작동하는 것처럼 보이고 게시물 데이터를 읽고 MySQL에 삽입하기 위해 간단한 PHP를 만듭니다.

Welcome <?php echo $_POST["fname"]; ?>!<br />
Your location is  <?php echo $_POST["location"]; ?> .
<?php $con = mysql_connect("localhost","root","");

if (!$con)
  {
  die('Could not connect: ' . mysql_error());
  }
$FirstName =$_POST["fname"]; 
$location =$_POST["location"];

mysql_select_db("test", $con); //what is your database name, 
//Create a table call persons, or u can use any table 
mysql_query("INSERT INTO my_db (firstName, location) 
VALUES ($FirstName,$location)");


mysql_close($con);
?>

그러나 페이지는 내 게시물 변수를 표시하지 않습니다. 그리고 그것은 MySQL에도 삽입되지 않습니다. 어떤 아이디어? 고마워

Answer 1

오류의 이유는 자동 제국 풀을 만들기 전에 자동 제출 객체를 만들려고하기 때문입니다.

코드를 main.c 파일에 배치 한 것 같습니다. iPhone 앱을 사용하면이 작업을 수행하고 싶지 않으므로 코드를 기본 앱 대의원 클래스 및 생성 된 클래스에 배치하려고합니다. 더 복잡한 것을 시도하기 전에 Hello World 앱을 먼저 만드는 것이 좋습니다.
