【问题描述】:
我一直在 localhost 上的网站上工作,并且刚刚尝试将其上传到免费的网络服务器,以便我可以得到一些测试人员,由于某种原因,我的代码被报告为恶意软件并被我的防病毒软件阻止,这意味着我在访问它时除了ERR_CONNECTION_RESET 什么都看不到。你们对为什么这段代码被检测为恶意软件有任何想法吗?
LOGIN.php
<?php
include('classes/db.php');
if (db::maintenance()) {
die('This site is currently going under maintenance, please check back again shortly.');
}
if (isset($_POST['submit'])) {
$username = $_POST['username'];
$password = $_POST['password'];
if (db::query('SELECT username FROM users WHERE username=:username', array(':username'=>$username))) {
if (password_verify($password, db::query('SELECT password FROM users WHERE username=:username', array(':username'=>$username))[0]['password'])) {
echo "Logged in!";
$cstrong = True;
$token = bin2hex(openssl_random_pseudo_bytes(64, $cstrong));
$user_id = db::query('SELECT id FROM users WHERE username=:username', array(':username'=>$username))[0]['id'];
db::query('INSERT INTO login_tokens VALUES (NULL, :token, :user_id)', array(':token'=>sha1($token), ':user_id'=>$user_id));
setcookie("SNID", $token, time() + 60 * 60 * 24 * 7, '/', NULL, NULL, TRUE);
setcookie('SNID_', '1', time() + 60 + 60 * 24 * 3, '/', NULL, NULL, TRUE);
header('Location: index.php');
} else {
echo "Incorrect password";
}
} else {
echo "User not registered!";
}
}
?>
<h1>Login to your account</h1>
<form action="login.php" method="post">
<input type="text" name="username" value="" placeholder="Username"><p />
<input type="password" name="password" value="" placeholder="Password"><p />
<input type="submit" name="submit" placeholder="Login"><p />
</form>
DB.php (我把连接改成了假数据,上传到主机的时候改成了正确的数据。)
<?php
class db {
private static function connect () {
$conn = new PDO('mysql:host=localhost;dbname=users;,charset=utf8', 'root', '');
$conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
return $conn;
}
public static function query ($sql, $params = array()) {
$statement = self::connect()->prepare($sql);
$statement->execute($params);
if (explode(' ', $sql)[0] == 'SELECT') {
$result = $statement->fetchAll();
return $result;
}
}
public static function notify ($userid) {
$notifications = db::query('SELECT forum_members.forum_id, notifications.user_id, notifications.post_id, notifications.forum_id, notifications.post_body, notifications.creation, notifications.type FROM forum_members, notifications WHERE (notifications.forum_id=forum_members.forum_id OR notifications.forum_id=0) AND notifications.user_id=forum_members.user_id ORDER BY notifications.post_id DESC');
return $notifications;
}
public static function maintenance () {
return false;
}
}
?>
【问题讨论】:
-
当你可以选择一次并使用下线获得的变量时,为什么要选择3次用户信息
-
这只是第一个标记之类的东西,以后我会再做一遍,我会改进代码。
-
db.php 中有什么?
-
检查编辑,添加数据库文件
