如何在Laravel中对每个响应强制执行JSON响应? [英] How do you force a JSON response on every response in Laravel?

问题描述

我正在尝试使用Laravel Framework构建REST api，我想要一种方法来强制API始终以JSON响应，而不是像这样进行操作:

I'm trying to build a REST api using Laravel Framework, I want a way to force the API to always responed with JSON not by doing this manulaly like:

return Response::json($data);

换句话说，我希望每个响应都是JSON.有什么好方法吗?

In other words I want every response to be JSON. Is there a good way to do that?

更新:即使在未找到类似异常的情况下，响应也必须为JSON

Update: The response must be JSON even on exceptions like not found exception.

推荐答案

要在控制器中返回JSON，只需return $data;

To return JSON in the controller just return $data;

对于错误的JSON响应，请转到app\Exceptions\Handler.php文件并查看render方法.

For a JSON response on errors, go to app\Exceptions\Handler.php file and look at the render method.

您应该可以重新编写它，使其看起来像这样:

You should be able to re-write it to look something like this:

public function render($request, Exception $e)
{
    // turn $e into an array.
    // this is sending status code of 500
    // get headers from $request.
    return response()->json($e, 500);
}

但是，您必须决定如何处理$e，因为它必须是array.您还可以设置状态代码和标头数组.

However you will have to decide what to do with $e, because it needs to be an array. You can also set the status code and header array.

但是如果发生任何错误，它将返回JSON响应.

But then on any error, it will return a JSON response.

还应注意，您可以更改report方法来处理laravel记录错误的方式.更多信息此处.

It's also good to note that you can change the report method to handle how laravel logs the error as well. More info here.
