使用PHP/MySQL和HTTP响应身份验证Iphone登录
问题描述:
我试图创建一个使用PHP/MySQL进行身份验证的iPhone目标C登录页面。我试图使用HTTP响应作为验证方式。无论你输入什么内容,它现在总是无法登录。使用PHP/MySQL和HTTP响应身份验证Iphone登录
`- (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];
}
`
和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);
?>
任何人有任何指针?即使它只是告诉我是否在PHP中正确地格式化我的repson。
在此先感谢。

感谢您的回复。我得到它的工作使用:
- (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;
}

根据您提供的示例,我没有看到您实际上发送了请求的用户名密码&。您正在创建一个字符串“发布”,但从未将其包含在请求中。
此外,该投:
NSHTTPURLResponse* httpResponse = (NSHTTPURLResponse*)request;
看起来不正确的。为什么要将请求对象转换为响应?
