Access Request in Service Provider After Applying Middleware
提问by schellingerht
Bindings
绑定
I'm using bindings in my service provider between interface and implementation:
我在我的服务提供者中在接口和实现之间使用绑定：
public function register()
{
$this->app->bind('MyInterface', MyImplementation::class);
}
Middleware
中间件
In my middleware, I add an attribute to the request:
在我的中间件中，我向请求添加了一个属性：
public function handle($request, Closure $next)
{
$request->attributes->add(['foo' => 'bar]);
return $next($request);
}
Now, I want to access fooin my service provider
现在，我想访问foo我的服务提供商
public function register()
{
$this->app->bind('MyInterface', new MyImplementation($this->request->attributes->get('foo')); // Request is not available
}
The register() is called before applying the middleware. I know.
在应用中间件之前调用 register()。我知道。
I'm looking for a technique to 'rebind' if the request->attributes->get('foo') is set
如果设置了 request->attributes->get('foo')，我正在寻找一种“重新绑定”的技术

Try like this:
像这样尝试：
public function register()
{
$this->app->bind('MyInterface', function () {
$request = app(\Illuminate\Http\Request::class);
return app(MyImplementation::class, [$request->foo]);
}
}
Binding elements works like this that they will be triggered only when they are call.
绑定元素是这样工作的，它们只有在被调用时才会被触发。

In service providerYou can also access Request Objectby:
在service provider您还可以Request Object通过以下方式访问：
public function register()
{
$request = $this->app->request;
}

I know this is old post. But I am having issue using this deferred service provider to define gates.
我知道这是旧帖子。但是我在使用这个延迟服务提供商来定义门时遇到了问题。
I am using Laravel 5.8
我正在使用 Laravel 5.8
Service provider: I want to defer loaded after having defined "foo" (in a middleware).
服务提供者：我想在定义“foo”（在中间件中）后推迟加载。
class MyServiceProvider extends ServiceProvider implements DeferrableProvider
{
protected $defer = true;
public function register()
{
$this->app->bind('MyImplementation', function () {
$request = app(\Illuminate\Http\Request::class);
return app(MyImplementation::class, [$request->foo]);
}
}
public function provides()
{
return [MyImplementation::class];
}
}
Here is how I handle in a middleware(adding "foo" and use the service provider). "foo" will be used to define Gates.
这是我在中间件中的处理方式（添加“foo”并使用服务提供者）。“foo”将用于定义盖茨。
public function handle($request, Closure $next)
{
$request->attributes->add(['foo' => 'bar']);
// Here I load gates
$myImpl = app(MyImplementation::class);
$myImpl ->loadGates();
return $next($request);
}
My service: define gate, For testing I just return "true" but never get into Gate::define().
我的服务：定义门，为了测试，我只返回“true”但从未进入 Gate::define()。
class MyImplementation
{
public function loadGates()
{
//dd("Test 1"); // reach here
Gate::define('create-user', function ($user) {
dd("Test 2"); //never reach here
// "foo" will be used here to define Gates.
return true;
});
}
}
I am wondering why I am not getting into Gate::define().
我想知道为什么我没有进入 Gate::define()。
Am I missing semething here please?
我在这里错过了什么吗？
Thanks
谢谢

Try this
尝试这个
public function register()
{
$this->app->bind('MyInterface', function ($app) {
return new MyImplementation(request()->foo);
}
}
