Laravel 5 - Use form request to validate JSON body

JsonBodyRequest.php

<?php

namespace <YourNamespace>\Http\Requests;

// To validate the content of the JSON body instead of query params, you need to override the getValidatorInstance() method to create the validator instance with $this->json()->all() instead for $this->all()
// This way you can keep your Requests as is and just extend this class instead when you need to validate jsonbody instead of query params

abstract class JsonBodyRequest extends Request{

    /**
     * Get the validator instance for the request.
     *
     * @return \Illuminate\Validation\Validator
     */
    protected function getValidatorInstance()
    {
        $factory = $this->container->make('Illuminate\Validation\Factory');

        if (method_exists($this, 'validator'))
        {
            return $this->container->call([$this, 'validator'], compact('factory'));
        }

        return $factory->make(
            $this->json()->all(), $this->container->call([$this, 'rules']), $this->messages(), $this->attributes()
        );
    }
}

i simply added this function in form request class

protected function validationData()
{
return $this->json()->all();
}

It worked for me.

// i created basic class for requests which could get JSON and usual requests.
// maybe it helps somebody

class ApiRequest extends FormRequest
{
protected function validationData()
{
return count($this->json()->all()) ? $this->json()->all() : $this->all();
}
}
