Question

我正在尝试为数据库开发接口，但是我在php中不是很实际。我想做的是登录后显示主页。但是，重定向不起作用。

所需行为： 1）index.php->登录表单/登录凭据

2）将凭据登录名发送到authenticate.php，如果一切正确，则查看主页

当前行为：发送凭据后，authenticate.php不会更改homepage.php中的页面，而是保留空白页面。

authenticate.php

<?php require_once ('connect.php');
ob_start();
session_start();

// Now we check if the data was submitted, isset will check if the data exists.
if ( !isset($_POST['username'], $_POST['password']) ) {
    // Could not get the data that should have been sent.
    die ('Username and/or password does not exist!');
}

if ($stmt = $connect->prepare('SELECT username, password FROM user WHERE username = ?')) {
    // Bind parameters (s = string, i = int, b = blob, etc), hash the password using the PHP password_hash function
    $stmt->bind_param('s', $_POST['username']);
    $stmt->execute();
    $stmt->store_result();

    // Store the result so we can check if the account exists in the database.
    if ($stmt->num_rows > 0) {
        $stmt->bind_result($username, $password);
        $stmt->fetch();
        $hash = hash('sha256', $_POST['password']);

        // Account exists, now we verify the password.
        if (hash_equals($password, $hash)) {
            $_SESSION['loggedin'] = TRUE;
            $_SESSION['username'] = $_POST['username'];

            header('Location: homepage.php');
            $output = ob_get_clean();
        } else {
            echo 'Incorrect username and/or password!';
        }

    } else {
        echo 'Incorrect username and/or password!';
    }
    $stmt->close();

} else {
    echo 'Could not prepare statement!';
}
?>

connect.php

<?php
$config = parse_ini_file('pathToFile...\credential.ini');
$connect = @mysqli_connect('localhost',$config['username'],$config['password'],$config['dbname']);
unset($config);
?>

homepage.php

<?php require_once ('connect.php');

// check to see if the user is logged in
if ($_SESSION['loggedin']) {
    // user is logged in
    echo 'Welcome!';

} else {
    // user is not logged in, send the user to the login page
    header('Location: index.php');
}
?>

登录后更改页面
