标签: php mysql mysqli xampp

我刚刚安装了xampp,并且正在phpMyAdmin上本地运行MySQL数据库。我正在尝试通过.php doc输出数据库的内容,但是在尝试这样做时会收到两个警告:

警告:mysqli :: __ construct():服务器在第20行的C:\ xampp \ htdocs \ footfallTracker \ test.php中请求客户端[caching_sha2_password]未知的身份验证方法

警告:mysqli :: __ construct():(HY000 / 2054):服务器在第20行的C:\ xampp \ htdocs \ footfallTracker \ test.php中请求客户端未知的身份验证方法 连接失败:服务器请求客户端未知的身份验证方法

这是我正在使用的代码:

     <?php
$servername = "localhost";
$username = "root";
$password = "*2470C0C06DEE42FD1618BB99005ADCA2EC9D1E19";
$dbname = "footfall_tracking";

// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

$sql = "SELECT ID, Location, Date FROM footstep_count";
$result = $conn->query($sql);

if ($result->num_rows > 0) {
    // output data of each row
    while($row = $result->fetch_assoc()) {
        echo "ID: " . $row["ID"]. " - Location: " . $row["Location"]. " - Date: " . $row["Date"]. "<br>";
    }
} else {
    echo "0 results";
}
$conn->close();
?>

答案 0 :(得分:0)

这段代码对我有帮助

ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password
BY 'password';
