JSON Request

{
  "title": "Hello World",
  "content": "Lorem ipsum."
}

Trying to make a JSON POST REQUEST and getting Status: 405 Method Not Allowed and I’m using php artisan serve, I could provide GIT project if necessary. Please let me know.

>Solution :

Your validation rules look incorrect. In your NoteRequest class, the rules should be an associative array where the keys are the field names and the values are the validation rules. However, in your code, the rules are defined as a comma-separated list of strings. This might cause the validation to fail and return a 405 Method Not Allowed error.

public function rules()
{
    return [
        'title' => 'required|max:255|min:3',
        'content' => 'nullable|max:255|min:10',
    ];
}
