seffeng / laravel-signature example snippets

# 1、生成配置文件
$ php artisan vendor:publish --tag="signature"

# 2、修改配置文件 /config/signature.php，或 .env

# 1、复制扩展内配置文件 /config/signature.php 到项目配置目录 /config

# 2、修改配置文件 /config/signature.php，或 .env

# 3、将以下代码段添加到 /bootstrap/app.php 文件中的 Providers 部分
$app->register(Seffeng\LaravelSignature\SignatureServiceProvider::class);

# 4、/bootstrap/app.php 添加配置加载代码
$app->configure('signature');

# 客户端示例
use Seffeng\Signature\Exceptions\SignatureException;
use Seffeng\LaravelSignature\Facades\Signature;

class SiteController extends Controller
{
    public function test()
    {
        try {
            /**
             * 客户端使用签名
             * @var string $method
             */
            $method = 'GET';
            $uri = '/test';
            $params = ['page' => 1];
            $signature = Signature::sign($method, $uri, $params);
            $headers = Signature::getHeaders();
            print_r($headers);

            // 其他客户端
            //$signature = Signature::setClient('other-client')->loadClient()->sign($method, $uri, $params);
            //$headers = Signature::getHeaders();
            //print_r($headers);

            // 通过请求传递 $headers，如使用 GuzzleHttp
            // $httpClient = new Client(['base_uri' => 'http://domain.com']);
            // $request = $httpClient->get('/test', ['headers' => $headers, 'query' => $params]);
        } catch (SignatureException $e) {
            var_dump($e->getMessage());
        } catch (\Exception $e) {
            var_dump($e->getMessage());
        }
    }
}

# 路由使用中间件，配置中间件
# 1、默认服务端：middleware('check.signature')
# 2、其他服务端：middleware('check.signature:other-server')

# 服务端示例，可通过中间件使用，或参考 /tests/SignatureTest.php
