Laravel 5: Custom abort() message
提问by Sharon Haim Pour
Using Laravel 5, I want to send a custom abort()message.
For example, if the user doesn't have the required permissions for an action,
I'd like to abort(401, "User can't perform this actions").
Currently, when I do so, the response text is HTML page and not the message.
How can I return only the message?
使用 Laravel 5，我想发送自定义abort()消息。
例如，如果用户没有操作所需的权限，
我想要abort(401, "User can't perform this actions").
目前，当我这样做时，响应文本是 HTML 页面而不是消息。
我怎样才能只返回消息？
Note:I don't want to pass a different view, but only the custom message.
注意：我不想传递不同的视图，而只想传递自定义消息。

According to Laravel 5.4 documentation:
根据 Laravel 5.4 文档：
https://laravel.com/docs/5.4/errors#http-exceptions
https://laravel.com/docs/5.4/errors#http-exceptions
You can use aborthelper with response text:
您可以将aborthelper 与响应文本一起使用：
abort(500, 'Something went wrong');
And use $exception->getMessage()in resources/views/errors/500.blade.phpto display it:
并使用$exception->getMessage()inresources/views/errors/500.blade.php来显示它：
Error message: {{ $exception->getMessage() }}

The answer is simply to use the response() helper method instead of abort(). Syntax as below.
答案只是使用 response() 辅助方法而不是 abort()。语法如下。
return response("User can't perform this action.", 401);

You can wrap a response inside abort, which will stop the execution and return the response. If you want it to be JSON then add ->json();
您可以在 abort 内包装响应，这将停止执行并返回响应。如果你希望它是 JSON 然后添加->json();
# Regular response
abort( response('Unauthorized', 401) );
# JSON response
abort( response()->json('Unauthorized', 401) );

Should be able to use the following in the template:
应该能够在模板中使用以下内容：
{{ $exception->getMessage() }}

You can handle all error exceptions here app/Exceptions/Handler.php Class On your requirement.
您可以在 app/Exceptions/Handler.php Class 根据您的要求处理所有错误异常。
In your case just replace render function with this
在你的情况下，只需用这个替换渲染功能
public function render($request, Exception $e)
{
return $e->getMessage();
//For Json
//return response()->json(['message' => $e->getMessage()]);
}

First of all add the error message in your header file or in the page where you want to show the message like:
首先在您的头文件或您想要显示消息的页面中添加错误消息，例如：
@if($errors->has())
@foreach ($errors->all() as $error)
<div>{{ $error }}</div>
@endforeach
@endif
And in the controller, you can do this kind of stuff (e.g.):
在控制器中，您可以执行以下操作（例如）：
public function store(){
if(user is not permitted to access this action) // check user permission here
{
return redirect()->back()->withErrors("User can't perform this actions");
}
}
You can redirect back with error message
您可以使用错误消息重定向回来

In Handler.phpI altered the function:
在Handler.php我改变了功能：
public function render($request, Exception $e)
{
$response = parent::render($request, $e);
if (method_exists($e, "getStatusCode")) {
if ($e->getStatusCode() == 401) {
$response->setContent($e->getMessage());
}
}
return $response;
}
