Laravel查询字符串少于/大于等

Question

在laravel中，我可以在资源控制器中写这个来响应获取请求（让我们说资源是产品）：

public function index(Request $request)
{
    // Handles requests such as ".../api/products?user_id=5&price=500"
    $products = Product::where($request->toArray())->get();
    return response($products);
}

这适用于使用＆＃34; =＆＃34;的请求，例如在示例中。但是，如果我们不想搜索价格= 500，但可能价格<= 500或价格＆gt; 500.对此最好的Laravel（和RESTful）方法是什么？

注意：Laravel 5.2

你可以这样做。

public function index(Request $request)
{
    // Handles requests such as ".../api/products?user_id=5&price=500"
    $products = Product::where('user_id', $request->user_id)->where('price', '<=', intval($request->price))->get();
    return response()->json($products);
}

或

public function index(Request $request)
{
    // Handles requests such as ".../api/products?user_id=5&price=500"
    $products = Product::whereRaw("user_id=? and price<=?", [$request->user_id, $request->price])->get();
    return response()->json($products);
}

在@Joel Hinz评论后编辑：

如果您还想传递查询的运算符，可以向网址添加新参数，例如

/api/products?user_id=5&price=500&op=1

然后切换控制器中的数字。

public function index(Request $request)
{
    // Handles requests such as ".../api/products?user_id=5&price=500&op=1"
    switch(intval($request->op)){
        case 1:
        $op = "<=";
        break;

        case 2:
        $op = ">";
        break;

        //and so on

        default:
        return response()->json("Wrong parameters");
        break;
    }

    $products = Product::whereRaw("user_id = ? and price $op ?", [$request->user_id, $request->price])->get();
    return response()->json($products);
}
