bug form-input给数组的时候，会报错

[aogg]

给数组，value必定null，这样就到不了array_merge

    /**
     * Get or set input data.
     *
     * @param  string|array  $key
     * @param  mixed  $value
     * @return array|mixed
     */
    public function input($key = null, $value = null)
    {
        if (is_null($key)) {
            return $this->inputs;
        }

        if (is_null($value)) {
            return Arr::get($this->inputs, $key);
        }

        if (is_array($key)) {
            $this->inputs = array_merge($this->inputs, $key);

            return;
        }

        Arr::set($this->inputs, $key, $value);
    }

$frorm->text('xxx')->saveAsJson()看看能达到你想要的不
