When I send an empty object to my Laravel API, it converts it into an empty array. This is a problem because I want to store this empty object as it is in my database.
Here is the body I send :

{
    "shouldBeEmptyArray": [],
    "shouldBeEmptyObject": {},
}

and here is the response I get if I just return the request content in my controller :

[
    [],
    []
]

If think this has something to do with the json() method inside Request.php, which use true value for the associative parameter of json_decode(), but I can’t find a way to make it work the way I want (and I don’t really want to change this file because it’s not a file of my project. I tried to override the method in my own Request custom class by extending Request but I doesn’t work). Here is the code of the json() method of Request.php :

    /**
     * Get the JSON payload for the request.
     *
     * @param  string|null  $key
     * @param  mixed  $default
     * @return SymfonyComponentHttpFoundationParameterBag|mixed
     */
    public function json($key = null, $default = null)
    {
        if (! isset($this->json)) {
            $this->json = new InputBag((array) json_decode($this->getContent(), true));
        }

        if (is_null($key)) {
            return $this->json;
        }

        return data_get($this->json->all(), $key, $default);
    }
