使用PHP/MySQL和HTTP响应对Iphone登录进行身份验证 [英] Authenticating Iphone Login with PHP/MySQL and HTTP Responses
本文介绍了使用PHP/MySQL和HTTP响应对Iphone登录进行身份验证的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我正在尝试使用PHP/MySQL进行身份验证以创建iPhone Objective C登录页面.我正在尝试使用HTTP响应作为身份验证的方式.现在,无论您输入什么,它始终无法登录.
Im trying to create a iPhone Objective C login page using PHP/MySQL to authenticate. Im trying to use HTTP responses as a way of authenticating. Right now it always fails to login , regardless of what you enter.
`- (IBAction) login: (id) sender
{
// this part isnt really implemented yet!
NSString *post =[NSString stringWithFormat:@"username=%@&password=%@",usernameField.text, passwordField.text];
NSURL *url = [NSURL URLWithString:@"MY URL HERE.php"];
NSURLRequest *request = [NSURLRequest requestWithURL: url];
NSHTTPURLResponse* httpResponse = (NSHTTPURLResponse*)request;
responseStatusCode = [httpResponse statusCode];
NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:response error:nil];
if ([responseStatusCode statusCode] == 200) {
//do something
UIAlertView *alertsuccess = [[UIAlertView alloc] initWithTitle:@"success" message:@"Your have logged in" delegate:self cancelButtonTitle:@"No" otherButtonTitles:@"Yes", nil];
[alertsuccess show];
[alertsuccess release];
}
else {
NSLog(@"Login failed.");
//do something else
UIAlertView *alertfail = [[UIAlertView alloc] initWithTitle:@"fail" message:@"login fail" delegate:self cancelButtonTitle:@"No" otherButtonTitles:@"Yes", nil];
[alertfail show];
[alertfail release];
}
`
PHP看起来像
<?
session_start();
require("iphoneconnection.php");
$u = $_POST['username'];
$pw = $_POST['password'];
$check = "SELECT username, password FROM iphoneusers WHERE username='$u' AND password= '$pw'";
$login = mysql_query($check, $connect) or die(mysql_error());
// check user level and store in $row
if (mysql_num_rows($login) == 1) {
$row = mysql_fetch_assoc($login);
//$_SESSION['level'] = $row['level'];
$_SESSION['username'] = $u;
echo 'login success';
header("HTTP/1.1 200 OK");
//header("Location: index.php");
} else {
//header("Location: login.php");
//echo '403 Forbidden';
header("403 Forbidden");
}
mysql_close($connect);
?>
有人知道吗?即使只是告诉我即时消息是否在PHP中正确格式化了我的回复.
Anyone got any pointers? Even if its just to tell me if Im formatting my repsonses correctly in the PHP.
提前谢谢.
推荐答案
感谢您的答复.我使用它来工作:
Thanks for the response. I got it to work using:
- (IBAction) login: (id) sender
{
NSString *post =[NSString stringWithFormat:@"username=%@&password=%@",usernameField.text, passwordField.text];
NSString *hostStr = @"MY URL.php?";
hostStr = [hostStr stringByAppendingString:post];
NSData *dataURL = [NSData dataWithContentsOfURL: [ NSURL URLWithString: hostStr ]];
NSString *serverOutput = [[NSString alloc] initWithData:dataURL encoding: NSASCIIStringEncoding];
if([serverOutput isEqualToString:@"Yes"]){
UIAlertView *alertsuccess = [[UIAlertView alloc] initWithTitle:@"success" message:@"You are authorized"
delegate:self cancelButtonTitle:@"No" otherButtonTitles:@"Yes", nil];
[alertsuccess show];
[alertsuccess release];
} else {
UIAlertView *alertsuccess = [[UIAlertView alloc] initWithTitle:@"Fail" message:@"Invalid Access"
delegate:self cancelButtonTitle:@"No" otherButtonTitles:@"Yes", nil];
[alertsuccess show];
[alertsuccess release];
}
loginIndicator.hidden = FALSE;
[loginIndicator startAnimating];
loginButton.enabled = FALSE;
}
