应用中间件后，服务提供商中的访问请求 [英] Access Request in Service Provider After Applying Middleware

问题描述

我在服务提供者中使用接口和实现之间的绑定:

I'm using bindings in my service provider between interface and implementation:

public function register()
{
    $this->app->bind('MyInterface', MyImplementation::class);
}

中间件

在我的中间件中，我向请求添加了一个属性:

Middleware

In my middleware, I add an attribute to the request:

public function handle($request, Closure $next)
{
    $request->attributes->add(['foo' => 'bar]);
    return $next($request);
}

现在，我要访问服务提供商中的foo

public function register()
{
    $this->app->bind('MyInterface', new MyImplementation($this->request->attributes->get('foo')); // Request is not available
}

在应用中间件之前调用register().我知道.

如果要设置request-> attributes-> get('foo')，我正在寻找一种重新绑定"的技术

The register() is called before applying the middleware. I know.

I'm looking for a technique to 'rebind' if the request->attributes->get('foo') is set

推荐答案

尝试如下:

public function register()
{
    $this->app->bind('MyInterface', function () {
        $request = app(\Illuminate\Http\Request::class);

        return app(MyImplementation::class, [$request->foo]);
    }
}

绑定元素的工作方式如下，只有在调用它们时才会触发它们.

Binding elements works like this that they will be triggered only when they are call.
