【问题描述】：

我正在为我的应用后端使用 php 和 slim 构建一个 restful api，而且我们有一个 web 版本，但我的团队使用纯 php 和 web 套装，我们分开工作。这只是我第一次承担后端责任 我对如何以安全和专业的方式处理身份验证有一个误解 我已经阅读了这个article 但我需要一个详细的方法来实现它在 php & slim 并将其扩展到 web 团队，以便使用相同的身份验证技术。

这是我使用的登录/注册代码： 帮我改进它：

    $app->post('/api/create_user', function( $request , $response , $args )

require('../config.php');


$email = $_POST['email'];
$qry= "select * from user where email ='". $email."'";

$result=$mysqli->query($qry);

if(mysqli_num_rows($result)>0)

$user = new stdClass();
$user->status=0;
$user->error=" the email is registered ";
$result = new stdClass();
$result->result=$user;




else 


$password = md5($_POST['password']);
$image=$_FILES['image']['name'];
$email=$_POST['email'] ;
$nickname =$_POST['nickname'];
$birthDay=$_POST['birthdate'];

$insert_req="INSERT INTO user VALUES ('', '$email', '$password','$nickname')";

$insert_user_result=$mysqli->query($insert_req);    

if ($insert_user_result) 

$user = new stdClass();
$user->status=1;
$result = new stdClass();
$result->result=$user;

else $user = new stdClass();
$user->status=2;
$user->error=mysql_error();
$result = new stdClass();
$result->result=$user;



if (isset($result))
    header('Content-type: application/json');
echo json_encode($result);

);


?>




    <?php
$app->post('/api/login', function( $request , $response , $args )
require('../config.php');

$email =$_POST['email'];
$password = md5($_POST['password']);

$findemail_qry= "select user_id from user where email ='". $email."'";
$findemail_result =$mysqli->query($findemail_qry);

if(mysqli_num_rows($findemail_result)>0)

$login_qry="select user_id from user where email ='". $email."'AND password ='".$password."'";
$login_result =$mysqli->query($login_qry);
if(mysqli_num_rows($login_result)>0)

 $data =mysqli_fetch_assoc ($login_result);

$user_id=$data['user_id']; 
$user = new stdClass();
$user->status=1;
$user->user_id=$user_id;
$result = new stdClass();
$result->result=$user;
           else
$user = new stdClass();
$user->status=2;
$user->error="wrong password";
$result = new stdClass();
$result->result=$user; 
       
           else 
$user = new stdClass();
$user->status=0;
$user->error=" this email not registered ";
$result = new stdClass();
$result->result=$user;


if (isset($result))
    header('Content-type: application/json');
echo json_encode($result);


       );
?>

【问题讨论】：

您可能想查看 API 框架以获取灵感。 github.com/tuupola/slim-api-skeleton

【参考方案1】：

您可以在您的超薄应用程序中使用 JWT 作为您 API 的身份验证层

你可以使用这个库来实现它 Slim JWT

你可以用一种简单的方式来使用这样的东西

尝试使用基本授权发送用户名和密码 然后您将生成一个新的 JWT 令牌，它将用于所有其他 API

<?php

use \Firebase\JWT\JWT;
use \Slim\Middleware\HttpBasicAuthentication\AuthenticatorInterface;

require '../vendor/autoload.php';

$app = new \Slim\App;

class RandomAuthenticator implements AuthenticatorInterface 
   public function __invoke(array $arguments) 

    //validation for user and password 
     $Password=$arguments['password'];
      $user=$arguments['user'];
if(($Password=="admin") &&($user=="admin") )
return true;
  
else

    return false ;

    



//add  http basic middleware for login route  
$app->add(new \Slim\Middleware\HttpBasicAuthentication([
    "path" => "/login",
     "realm" => "Protected",
    "authenticator" => new RandomAuthenticator()

]));


$app->post("/login", function ($request, $response, $arguments) 
//generate JWT token 
    $now = new DateTime();
    $future = new DateTime("now +20 minutes");
    $server = $request->getServerParams();

    $payload = [
        "iat" => $now->getTimeStamp(),
        "exp" => $future->getTimeStamp(),
        "sub" => $server["PHP_AUTH_USER"],
    ];
    $secret = "TOURSECERTKEY";
    $token = JWT::encode($payload, $secret, "HS512");
    $data["status"] = "ok";
    $data["token"] = $token;

    return $response->withStatus(201)
        ->withHeader("Content-Type", "application/json")
        ->write(json_encode($data, JSON_UNESCAPED_SLASHES | JSON_PRETTY_PRINT));
);
//Add jWT token Authorization middleware for all API  
$app->add(new \Slim\Middleware\JwtAuthentication([
     "path" => ["/"],
    "passthrough" => ["/login"],
    "secret" => "TOURSECERTKEY",
    "error" => function ($request, $response, $arguments) 
        $data["status"] = "error";
        $data["message"] = $arguments["message"];
        return $response
            ->withHeader("Content-Type", "application/json")
            ->write(json_encode($data, JSON_UNESCAPED_SLASHES | JSON_PRETTY_PRINT));
    
]));
