laravel怎么实现一个全局的HTTP客户端中间件_laravel全局HTTP客户端中间件实现方法

<?php

namespace App\Http\Middleware;

use Closure;

class GlobalHttpClientMiddleware
{
    public function handle($request, Closure $next)
    {
        // 在发送请求前可以修改请求
        // 例如：统一添加 header
        $request->withHeader('X-Client', 'Laravel-Global');

        return $next($request);
    }
}

// app/Services/Http/GlobalRequestMiddleware.php

namespace App\Services\Http;

use Psr\Http\Message\RequestInterface;

class GlobalRequestMiddleware
{
    public function handle()
    {
        return function (callable $handler) {
            return function (RequestInterface $request, array $options) use ($handler) {
                // 修改请求：例如添加全局 Header
                $request = $request->withHeader('User-Agent', 'MyApp/1.0');
                $request = $request->withHeader('X-Timestamp', now()->toISOString());

                // 可以在这里记录日志
                \Log::info('Outgoing request: ' . $request->getMethod() . ' ' . $request->getUri());

                // 继续处理请求
                return $handler($request, $options);
            };
        };
    }
}

php artisan make:provider HttpClientServiceProvider

<?php

        Http::macro('withGlobalHeaders', function () use ($middleware) {
            return $this->withMiddleware($middleware->handle());
        });

        // 设置默认行为（可选：对所有请求生效）
        Http::withMiddleware($middleware->handle());
    }
}

'providers' => [
    // 其他服务提供者...
    App\Providers\HttpClientServiceProvider::class,

$response = Http::get('https://api.example.com/data');
