[英]SQLSTATE[28000][1045] Access denied for user 'root'@'localhost'(using password:NO)
[英]MySQLI 28000/1045 Access denied for user 'root'@'localhost'
我遇到了麻烦。 因此,我尝试使用MySQLi连接到我的数据库,但出现此错误:
Warning: mysqli::mysqli(): (28000/1045): Access denied for user 'root'@'localhost' (using password: NO) in /home/venge/public_html/library/classes/database.class.php on line 16
Warning: Missing argument 1 for Users::__construct(), called in /home/venge/public_html/routing.php on line 4 and defined in /home/venge/public_html/library/classes/users.class.php on line 3
Warning: mysqli::mysqli(): (28000/1045): Access denied for user 'root'@'localhost' (using password: NO) in /home/venge/public_html/library/classes/database.class.php on line 16
Warning: Cannot modify header information - headers already sent by (output started at /home/venge/public_html/library/classes/database.class.php:16) in /home/venge/public_html/routing.php on line 11
。 我不知道为什么它作为用户说“ root”,我的代码在下面。 我可以用该信息登录到PHPMyAdmin。
<?php
$db['host'] = 'localhost';
$db['user'] = 'venge_main';
$db['pass'] = 'fakepassword';
$db['name'] = 'venge_panel';
class DB {
function __construct($db) {
$this->mysqli = new mysqli($db['host'], $db['user'], $db['pass'], $db['name']);
}
function query($i) {
return $this->mysqli->query($i);
}
function fetch_array($i) {
return $i->fetch_array(MYSQLI_ASSOC);
}
function num($i) {
return $i->num_rows;
}
}
?>
这是我的global.php文件:
<?php
session_start();
$venge['library'] = 'library/classes/';
include_once($venge['library'] . 'users.class.php');
include_once($venge['library'] . 'database.class.php');
$users = new Users($database);
?>
这是我的用户类:
<?php
class Users {
public function __construct($db) {
$this->db = new DB($db);
}
public function uidset() {
if (isset($_SESSION['uid'])) {
return true;
} else {
return false;
}
}
public function securitycheck() {
if (isset($_SESSION['uid'])) {
//passed
return true;
} else {
//failed
die('No permissions');
}
}
}
?>
这是routing.php:
<?php
class Routing {
public function __construct($route) {
$this->users = new Users();
$this->route = $route;
}
public function File() {
if (!$this->users->uidset()) {
switch ($this->route) {
default:
header("Location: /user/login");
break;
case '/user/login':
include_once('library/pages/login.page.php');
break;
}
} else {
switch ($this->route) {
default:
header("Location: /venge");
break;
case '/venge':
echo 'Welcome to <strong>Venge</strong> .';
break;
}
}
}
}
$route = new Routing($_SERVER['ORIG_PATH_INFO']);
$route->File();
?>
错误的原因在这里:
class Routing {
public function __construct($route) {
$this->users = new Users();//<-?
$this->route = $route;
}
您没有将参数传递给Users .__ construct($ db)
用凭据定义一个数组,并传递如下:
class Routing {
public function __construct($route) {
$db = array();
$db['host'] = 'localhost';
$db['user'] = 'venge_main';
$db['pass'] = 'fakepassword';
$db['name'] = 'venge_panel';
$this->users = new Users($db);
$this->route = $route;
}
或者使用全局$ db变量,而不是像我一样在本地定义它。 但是在创建Users对象时必须将其传递给构造函数。
$users = new Users($database);
我认为必须是:
$users = new Users($db);
如果$ db在该文件中定义。
通常这意味着您的host
, database
, user
或password
是错误的。
就我而言,它是host
,我通常使用localhost,但是这次我在cPanel
> MySQL® Databases
看到我不应该使用localhost,而我应该使用mysql5.xxxxxxx.net。
这是对我有帮助的信息:
mysql服务器的地址是mysql5.xxxxxxxx.net。 连接到mysql服务器时,必须指定该主机。
