在laravel中默认返回的异常是html的形式展现在页面上面，当我们写api接口时候希望返回json给前端希望能够不会出现神奇的bug。
找到文件Exceptions\Handler.php重写render方法
重写代码
/**
* 重写render
* @param $request
* @param Throwable $e
* @return \Illuminate\Http\JsonResponse|\Illuminate\Http\Response|\Symfony\Component\HttpFoundation\Response|void
* @throws Throwable
*/
public function render($request, Throwable $e)
{
if (!$request->is('api/*')) {
return parent::render($request, $e);
}
$error = $this->convertExceptionToResponse($e);
$api_e = FlattenException::create($e);
$debug['line'] = $api_e->getLine();
$debug['file'] = $api_e->getFile();
$debug['class'] = $api_e->getClass();
$debug['trace'] = $api_e->getTrace();
return response()->json([
'status' => false,
'code'=>$error->getStatusCode(),
'message'=>$api_e->getMessage(),
'data'=>$debug,
], $error->getStatusCode());
}
