Laravel 5.3 Password Broker Customization

问题

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:

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'];
    }
}

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

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'])
);
}

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.

There are some missing things for step 1 & 3 in the answer https://stackoverflow.com/a/42855948/2311074

Step 1

Probably the safest way is to simply copy the class from Illuminate\Auth\Passwords\PassswordResetServiceProvider.php to App\Provider\CustomPasswordResetServiceProviderand change:

Namespace to namespace App\Providers;
Class name to CustomPasswordResetServiceProvider
Add use App\Services\CustomPasswordBrokerManager; to the top
Inside the function registerPasswordBroker rename PasswordBrokerManager to CustomPasswordBrokerManager

Step 2.

Besides changing the resolve method also do the following:
