PHP7 OAuth2 Extension Installation Guide

OAuth2 is an open standard for authorizing systems to access protected resources. In PHP development, the OAuth2 extension package can help us implement the OAuth2 authorization process more easily, allowing our applications to authorize interactions with third-party services. This article will introduce you to how to install the OAuth2 extension in PHP7 and provide specific code examples.

Step 1: Install the OAuth2 extension

First, we need to install the OAuth2 extension. You can install it through Composer and execute the following command:

composer require bshaffer/oauth2-server-php

Composer will install the latest version of the OAuth2 extension package for you.

Step 2: Configure OAuth2

Next, we need to configure OAuth2 to run correctly. Create a new PHP file and introduce OAuth2 related class files into it:

require_once 'vendor/autoload.php';

use OAuth2Server;
use OAuth2StoragePdo;
use OAuth2GrantTypeClientCredentials;
use OAuth2GrantTypeAuthorizationCode;

Then, we need to configure the database connection information so that OAuth2 can store authorization information in the database. Add the following code to your configuration file:

$dsn = 'mysql:dbname=oauth2_db;host=localhost';
$username = 'username';
$password = 'password';

$pdo = new PDO($dsn, $username, $password);

Step Three: Create OAuth2 Server

Next, let’s create an OAuth2 server instance and add the required authorization type:

$storage = new OAuth2StoragePdo($pdo);

$server = new OAuth2Server($storage);

$server->addGrantType(new ClientCredentials($storage)); // 添加客户端凭据授权类型
$server->addGrantType(new AuthorizationCode($storage)); // 添加授权码授权类型

Step 4: Process the authorization request

Finally, we need to process the authorization request and verify the user's identity. The following is a simple sample code:

$request = OAuth2Request::createFromGlobals();
$response = new OAuth2Response();

if (!$server->validateAuthorizeRequest($request, $response)) {
    $response->send();
    die;
}

if (empty($_POST)) {
    exit('<form method="post"><label>Do You Authorize TestClient?</label><input type="submit" name="authorized" value="yes"><input type="submit" name="authorized" value="no"></form>');
}

$is_authorized = ($_POST['authorized'] === 'yes');
$server->handleAuthorizeRequest($request, $response, $is_authorized);
$response->send();

Conclusion

Through the above steps, you have successfully installed the OAuth2 extension and implemented a simple OAuth2 authorization process. Of course, in actual applications, you may need to perform more configuration and customization according to specific needs. I hope this article was helpful and good luck with your use of OAuth2 extensions!
