连接失败:用户 ''username'@'localhost' 访问被拒绝(使用密码:YES)
我正在尝试连接到服务器上的 MySQL,但出现以下错误.用户已创建并被授予所有权限.
I am trying to connect to MySQL on the server but gives following error. User is created and granted all privileges.
它可以在本地机器上运行,但在部署到服务器之后就不行了.
还有 mysql_connect
函数可以工作,但是 new mysqli()
给出如下所述的拒绝访问.
Also mysql_connect
function works but new mysqli()
gives access denied as mentioned below.
也尝试添加端口.
警告: mysqli::mysqli(): (HY000/1045): Access denied for user ''usernam'@'localhost' (using password: YES) in/home/domainname/public_html/autopublish/test.php on8号线连接失败:用户 ''username'@'localhost' 访问被拒绝(使用密码:YES)

<?php
$servername = "localhost";
$username = "'xxxxx";
$password = "xxxxx";
$dbname = "xxxxx";
// Create connection
$conn = new mysqli($servername, $username, $password); **//line 8**
// Check connection

} else {
echo "no connection";
}
$sql = "SELECT * FROM pages";
$result = $conn->query($sql);
$data = array();
$arr = array();
if ($result->num_rows > 0) {
// output data of each row
while($row = $result->fetch_assoc()) {
}
} else {
echo "No Token";
}
print_r(json_encode($data));
$conn->close();
?>
推荐答案
要么用户没有数据库所需的权限,要么密码错误.
Either the user does not have the required rights for the database or the password is wrong.
否则删除用户并使用以下语句创建:
Otherwise remove the user and use the following statement to create:
1.CREATE USER 'user'@'localhost' IDENTIFIED BY '123456789';
2.
3.GRANT ALL PRIVILEGES ON project.* TO 'user'@'localhost' WITH GRANT OPTION;
或者试试这个:
<?php
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "dbname";
//Create
mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);
$conn = new mysqli($servername, $username, $password, $dbname);
echo "Yaaay";
