使用Laravel构建REST JSON API

Question

I need to build a mobile version of my application. The mobile app is going to have the same functionality and for this I need to build an API for my web application that can be accessed from the mobile client.

Let's have an example: I have a controller class called PostController that is responsible for the posts in the application. This is a resource controller.

Route::resource("users.posts", "PostController");

When the user access http://domain.com/users/{id}/posts/{id} , he gets a rendered HTML response. This is done in the PostController@show method:

public function show($user_id, $post_id) {
    $post = Post::findOrFail($post_id);
    // other logic here

    return view("post.show", ["post" => $post_id]);
}

But now the user launches his mobile application which queries http://api.domain.com/users/{id}/posts/{id} . I know I could create a separate controller for the API, but this would result to code duplication. Hard to maintain, not a clever idea.

How do I make a JSON API that takes advantage of the existing controllers?

Maybe something like

public function show($user_id, $post_id) {
    $post = Post::findOrFail($post_id);
    // other logic here

    if(is api.domain.com) {
        return json
    } else {
        return view("post.show", ["post" => $post_id]);
    }

}

I need to secure the API with OAuth and I have used the oauth2-server-laravel package.

这主要是个人喜好，我会使用单独的控制器，因为我将api和网络应用视为单独的应用。
