我正在尝试将数据从iPhone发布到PHP web服务器。这是我下面的代码：iPhone编程发布数据
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;
}
调试器窗口输出：

Welcome Test!<br />
Your location is Germany .
</body>
似乎工作，然后我创建了一个简单的PHP读取后的数据，并将其插入到MySQL ：
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);
?>
但该页面不显示我的发布变量。它也不会插入到mysql中。有任何想法吗？谢谢你
