Here is what I use (Laravel 5.2):

According to: <a href="https://laravel.com/docs/5.2/errors">https://laravel.com/docs/5.2/errors</a> , we can specify a custom render function for errors in <code>app\Exceptions\Handler.php</code>. All I did was to change my render function to this:

<pre><code> /**
 * Render an exception into an HTTP response.
 * Updated to return json for a request that wantsJson 
 * i.e: specifies 
 * Accept: application/json
 * in its header
 *
 * @param \Illuminate\Http\Request $request
 * @param \Exception $e
 * @return \Illuminate\Http\Response
 */
 public function render($request, Exception $e)
 {
 if ($request-&gt;ajax() || $request-&gt;wantsJson()) {
 return response()-&gt;json(
 $this-&gt;getJsonMessage($e), 
 $this-&gt;getExceptionHTTPStatusCode($e)
 );
 }
 return parent::render($request, $e);
 }

 protected function getJsonMessage($e){
 // You may add in the code, but it's duplication
 return [
 'status' =&gt; 'false',
 'message' =&gt; $e-&gt;getMessage()
 ];
 }

 protected function getExceptionHTTPStatusCode($e){
 // Not all Exceptions have a http status code
 // We will give Error 500 if none found
 return method_exists($e, 'getStatusCode') ? 
 $e-&gt;getStatusCode() : 500;
 }
</code></pre>

After this, all you need do is make sure all your API requests specify the <code>Accept: application/json</code> header. Hope this helps :)

blocks|key|140911|text|为了返回与内置validate方法相同类型的响应，我在5.6中使用了以下内容：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|140912|response()->json(['errors'+=>+['email'+=>+['The+email+is+invalid.']]],+422);|140913|entityMap^0|7|8|0|0|24|0^^$0|@$1|2|3|4|5|6|7|J|8|@$9|K|A|L|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|M|8|@$9|N|A|O|B|C]]|D|@]|E|$]]|$1|H|3|-4|5|6|7|P|8|@]|D|@]|E|$]]]|I|$]]

I'm developing some kind of RESTful API. When some error occurs, I throw an <code>App::abort($code, $message)</code> error. 

The problem is: I want him to throw a json formed array with keys "code" and "message", each one containing the above mentioned data. 

<pre><code>Array
(
 [code] =&gt; 401
 [message] =&gt; "Invalid User"
)
</code></pre>

Does any one knows if it's possible, and if it is, how I do it?

How can I make Laravel return a custom error for a JSON REST API

JSON

我正在开发某种RESTful应用程序接口。当发生一些错误时，我抛出一个App::abort($code, $message)错误。问题是:我希望他抛出一个带有键"code“和"message”的json格式的数组，每个键都包含上面提到的数据。Array(    [code] => 401    [message] =>...
