Laravel 5 - 错误调用未定义的方法Illuminate \ Events \ Dispatcher :: fire（）

I'm working on a REST API using JWT.

The login route is good, but the router in group middleware jwt.auth doesn't work.

Error:

Symfony\Component\Debug\Exception\FatalThrowableError: Call to undefined method Illuminate\Events\Dispatcher::fire()

My code:

Route::group(['namespace' => 'Api'], function(){

    Route::get('user/login', 'AuthController@login');

    Route::group(['middleware' => ['jwt.auth']], function() {            
        Route::get('auth/me', 'AuthController@me');
    });
});

Well, i solved this error. them of 2hours..... :/

I modified the files Dispatcher.php of laravel.

Solution:

1) first in the file vendor\laravel\framework\src\Illuminate\Events\Dispatcher.php

1.1)Add this code.

/**
 * Fire an event and call the listeners.
 *
 * @param  string|object  $event
 * @param  mixed  $payload
 * @param  bool  $halt
 * @return array|null
 */
public function fire($event, $payload = [], $halt = false);

2) them in the second file. vendor\laravel\framework\src\Illuminate\Contracts\Events\Dispatcher.php

2.1)Add this code.

/**
 * Fire an event and call the listeners.
 *
 * @param  string|object  $event
 * @param  mixed  $payload
 * @param  bool  $halt
 * @return array|null
 */
public function fire($event, $payload = [], $halt = false)
{
    return $this->dispatch($event, $payload, $halt);
}

fire was changed to dispatch in laravel 5.8 here https://github.com/laravel/framework/pull/26392

If you use tymondesigns/jwt-auth package, this issue help you : https://github.com/tymondesigns/jwt-auth/issues/1787

This version fix this problem : https://github.com/tymondesigns/jwt-auth/releases/tag/1.0.0-rc.4

The Event method fire is deprecated in Laravel v5.8 However it works on prior version of Laravel v5.7 You can use the method dispatch in Laravel v5.8 and later. It works same as fire method and dispatches the event to event handler function registered in EventServiceProvider

JWT still using fire method and it's replced with dispatch method in Laravel 5.8 so the solution should change the method call in JWT.

this solution worked with me on Laravel 5.8

go to this path in your project

\vendor\tymon\jwt-auth\src\Middleware\GetUserFromToken.php

this is the original code:

    public function handle($request, \Closure $next)
{
    if (! $token = $this->auth->setRequest($request)->getToken()) {
        return $this->respond('tymon.jwt.absent', 'token_not_provided', 400);
    }

    try {
        $user = $this->auth->authenticate($token);
    } catch (TokenExpiredException $e) {
        return $this->respond('tymon.jwt.expired', 'token_expired', $e->getStatusCode(), [$e]);
    } catch (JWTException $e) {
        return $this->respond('tymon.jwt.invalid', 'token_invalid', $e->getStatusCode(), [$e]);
    }

    if (! $user) {
        return $this->respond('tymon.jwt.user_not_found', 'user_not_found', 404);
    }

    $this->events->fire('tymon.jwt.valid', $user);

    return $next($request);
}

and you should change:

$this->events->fire('tymon.jwt.valid', $user)

to:

$this->events->dispatch('tymon.jwt.valid', $user);

you only replace fire method with dispatch because fire method is not available in Laravel 5.8 and the newest way is using dispatch method.

I hope this solution working with you..

Changed fire() to dispatch() for Laravel 5.8+
