To return a SQL query using JWT in PHP, you can create a function that first verifies the JWT token and then executes the SQL query. Here is an example code snippet to demonstrate this:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 |
<?php
require 'vendor/autoload.php'; // Include JWT library
use FirebaseJWTJWT;
// Secret key for JWT verification
$key = "secret_key";
// JWT token from request header
$token = $_SERVER['HTTP_AUTHORIZATION'];
try {
// Verify JWT token
$decoded = JWT::decode($token, $key, array('HS256'));
// If token is valid, execute SQL query
$conn = new PDO("mysql:host=localhost;dbname=mydatabase", "username", "password");
$stmt = $conn->prepare("SELECT * FROM my_table");
$stmt->execute();
// Fetch data from query result
$result = $stmt->fetchAll(PDO::FETCH_ASSOC);
// Return SQL query result
header('Content-Type: application/json');
echo json_encode($result);
} catch (Exception $e) {
// If JWT token is not valid, return error message
echo "Invalid token";
}
?>

In this code snippet, we first verify the JWT token using the secret key. If the token is valid, we then connect to the database and execute a SQL query to fetch data from a table. Finally, we return the query result as JSON response. If the JWT token is not valid, we return an error message.
Make sure to replace the database connection details, table name, and SQL query with your specific requirements. Also, ensure that you have installed the Firebase JWT library using Composer before running this code.
