How to use Workerman to implement the user login authentication function of PHP and Unity3D

Introduction:
When developing web applications or games, the user login authentication function is an essential part. As PHP is the mainstream language for web development, Unity3D is a popular tool for game development. How to implement the user login authentication function between PHP and Unity3D has become a hot topic. This article will introduce how to use Workerman to implement the user login authentication function of PHP and Unity3D.

1. What is Workerman?
Workerman is a high-performance asynchronous event-driven development framework based on PHP, which can be used to build various high-performance network applications. Workerman provides a complete set of network programming interfaces, which can easily create TCP/UDP servers and implement functions such as instant messaging and game servers.

2. Requirements analysis:
The function we need to implement is that the PHP server is used for user login authentication, and the Unity3D client completes the user login verification process by communicating with the PHP server. The specific process is as follows:

1. The Unity3D client sends the user's username and password to the PHP server;
2. After the PHP server receives the request, it verifies the correctness of the username and password;
3. The PHP server returns the verification results to the Unity3D client, and the client can make corresponding processing based on the returned results.

3. Code implementation:

1. Unity3D client code:

   using System.Collections;
   using System.Collections.Generic;
   using UnityEngine;
   using UnityEngine.Networking;
   
   public class LoginManager : MonoBehaviour
   {
    public string loginUrl = "http://your-php-server.com/login.php";
    public string username;
    public string password;
   
    public void Login()
    {
        StartCoroutine(DoLogin());
    }
   
    IEnumerator DoLogin()
    {
        WWWForm form = new WWWForm();
        form.AddField("username", username);
        form.AddField("password", password);
   
        UnityWebRequest www = UnityWebRequest.Post(loginUrl, form);
        yield return www.SendWebRequest();
   
        if (www.isNetworkError || www.isHttpError)
        {
            Debug.Log(www.error);
        }
        else
        {
            Debug.Log(www.downloadHandler.text);
        }
    }
   }

2. PHP server code:

   require_once __DIR__ . '/workerman/Autoloader.php';
   
   use WorkermanWorker;
   
   $worker = new Worker('tcp://0.0.0.0:8000');
   
   $worker->onMessage = function($connection, $data) {
    $requestData = json_decode($data, true);
   
    $username = $requestData['username'];
    $password = $requestData['password'];
   
    // 进行用户名和密码的验证
    if ($username == 'admin' && $password == '123456') {
        $connection->send(json_encode(['result' => true]));
    } else {
        $connection->send(json_encode(['result' => false]));
    }
   };
   
   Worker::runAll();

4. Instructions for use:

1. First, download and extract Workerman’s source code to a directory on the PHP server, such as /path /to/workerman;
2. Create a login interface in Unity3D, and add the above Unity3D client code to the OnClick event of the login button;
3. In the PHP server, add The above PHP server code is saved as a login.php file and placed in a directory accessible to any web server;
4. Start the Workerman server: php /path/to/workerman /start.php start -d;
5. Run the Unity3D client, enter the correct username and password, and click the login button. The Unity3D client will send a login request to the PHP server, and the PHP server will return the username and password. Validation results.

5. Summary:
This article introduces how to use Workerman to implement the user login authentication function of PHP and Unity3D. Through the above sample code, we can learn how to send a login request to the PHP server on the Unity3D client and make corresponding processing based on the verification results returned by the PHP server. Through Workerman, a high-performance network programming framework, we can easily achieve communication between PHP and Unity3D. Hope this article can be helpful to you.
