在 Laravel 中使用 try 和 catch 处理错误

发布于10月31日

我想在我的应用程序中实现一个好的错误处理，我已经强制这个文件来捕获错误.

App\Services\PayUService

try {
  $this->buildXMLHeader; // Should be $this->buildXMLHeader();
} catch (Exception $e) {
        return $e;
}

App\Controller\ProductController

function secTransaction(){
  if ($e) {
    return view('products.error', compact('e'));
  }
}

And this is what I get.

I don't know why Laravel is not redirecting me to the view. Is the error forced right?

推荐答案

You are inside a namespace so you should use \Exception to specify the global namespace:

try {

  $this->buildXMLHeader();

} catch (\Exception $e) {

    return $e->getMessage();
}

In your code you've used catch (Exception $e) so Exception is being searched in/as:

App\Services\PayUService\Exception

因为App\Services\PayUService里面没有Exception类，所以它不会被触发.或者，你可以在类的顶部使用use语句，比如use Exception;，然后使用catch (Exception $e).
