Laravel 5.3密码代理定制

Question

Does anyone know how to override the functions used within laravel's password broker? I know the docs:

https://laravel.com/docs/5.3/passwords#resetting-views

Give information on what to do for things like views and a few surface level things but it's not clear at all really or maybe I'm not reading it enough times.

I already know how to override the ResetsPasswords.php Trait but overriding the functionality of the Password::broker() is for the next layer in.

If there is more information needed I can kindly provide some.

Thank you in advance.

I had to face the same issue, needed to override some of the PasswordBroker functions. After a lot of investigation on the web and many failed attempts to do so, I ended up to the following implementation:

1. Created a CustomPasswordResetServiceProvider inside App\Providers where I registered a CustomPasswordBrokerManager instance.

   namespace App\Providers;
   use Illuminate\Support\ServiceProvider;
   use App\Services\CustomPasswordBrokerManager; 
   class CustomPasswordResetServiceProvider extends ServiceProvider{
       protected $defer = true;
   
       public function register()
       {
           $this->registerPasswordBrokerManager();
       }
   
       protected function registerPasswordBrokerManager()
       {
           $this->app->singleton('auth.password', function ($app) {
               return new CustomPasswordBrokerManager($app);
           });
       }
   
       public function provides()
       {
           return ['auth.password'];
       }
   }
   

2. In config/app.php commented out line:
   //Illuminate\Auth\Passwords\PasswordResetServiceProvider::class,
   and added:
   App\Providers\CustomPasswordResetServiceProvider::class,

3. Inside App\Services folder created a CustomPasswordBrokerManager and copied the context of the default PasswordBrokerManager located at:
   Illuminate\Auth\Passwords\PasswordBrokerManager.php
   Then modified the function resolve to return an instance of my CustomPasswordProvider class.

   protected function resolve($name)
   {
       $config = $this->getConfig($name);
       if (is_null($config)) {
           throw new InvalidArgumentException("Password resetter [{$name}] is not defined.");
       }
   
       return new CustomPasswordBroker(
           $this->createTokenRepository($config),
           $this->app['auth']->createUserProvider($config['provider'])
   );
   }
   

4. Finally inside App\Services folder I created a CustomPasswordBroker class which extends default PasswordBroker located at:
   Illuminate\Auth\Passwords\PasswordBroker and overridden the functions that I needed.

   use Illuminate\Auth\Passwords\PasswordBroker as BasePasswordBroker;    
   
   class CustomPasswordBroker extends BasePasswordBroker    
   {    
   // override the functions that you need here    
   }      
   

Not sure if this is the best implementation but it worked for me.
