Laravel php 工匠“类请求不存在”

Question

I'm working with Laravel,

suddenly when I try to run php artisan serve in my command prompt,

it's displaying the error message:

In Container.php line 729: Class request does not exist

I have looked in all my controllers, models, and other files I could think of for loose Request references, but found nothing.

How do I debug this?

Answer 1

I was having this problem because a config file was calling the request helper function.

Since I did not use this configuration when running my application from console, I just checked if the request was running from console before using the request helper. For example,

# my config file

return [
    'conf_key' => (app()->runningInConsole() === false) ? request()?->headers?->get('origin') : null,
// ...

Answer 2

Recheck your Controller class exists, because this error is thrown when there is some difference in Controller class name like

class PostController extends Controller { }

and

class Postcontroller extends Controller { }

Notice small "C"

Answer 3

In my case it was a problem with permission to bootstrap/cache on CI server. Check this directory twice.

Answer 4

我在 bootstrap 目录中创建了一个缓存目录，我的问题解决了

Answer 5

I was using request() in config.php , and I don't know why this works until some day that crash with this error. The site was working well, but composer/artisan commands fail. I think it's normal, because there is no request... I handled checking isset($_SERVER["SERVER_NAME"]) , because I need the SERVER_NAME to config some parameters.

Answer 6

I struggled with this issue for a while.

/**
 * Instantiate a concrete instance of the given type.
 *
 * @param  string  $concrete
 * @return mixed
 *
 * @throws \Illuminate\Contracts\Container\BindingResolutionException
 */
public function build($concrete)
{
    // If the concrete type is actually a Closure, we will just execute it and
    // hand back the results of the functions, which allows functions to be
    // used as resolvers for more fine-tuned resolution of these objects.
    if ($concrete instanceof Closure) {
        return $concrete($this, $this->getLastParameterOverride());
    }

    echo 'Build - ' . $concrete . PHP_EOL;
    $reflector = new ReflectionClass($concrete);
