跟踪如何将带有http身份验证的http请求发送到php文件

我有一个php文件test.php，它创建了HTTP Auth。

$valid_passwords = array ("test" => "test123");
        $valid_users = array_keys($valid_passwords);
        $user = $_SERVER['PHP_AUTH_USER'];
        $pass = $_SERVER['PHP_AUTH_PW'];
        $validated = (in_array($user, $valid_users)) && ($pass == $valid_passwords[$user]);
        if (!$validated) {
          header('WWW-Authenticate: Basic realm="My Realm"');
          header('HTTP/1.0 401 Unauthorized');
          die ("Not authorized");
        }
        // If arrives here, is a valid user.
        echo "<p>Welcome $user.</p>";
        echo "<p>Congratulation, you are into the system.</p>";
            }

现在我想访问test.php并从rails平台发送一个get请求，我已经尝试过了：

url = 'http://url/test.php'
        uri = URI.parse(url)
        http = Net::HTTP.new(uri.host, uri.port)
        request = Net::HTTP::Get.new(uri.path,'Authorization' => "test test123")
        response = http.request(request)
        render :text => response.body

"它不起作用，"未经授权的人说。我可以在PHP和Rails中进行更改，我只需要一种安全的方式在两者之间发出http请求。
