Lumen 5.6 错误处理（两次抛出异常）

Question

这是我处理任何错误的代码：

App\Exceptions\Handler::class

public function render($request, Exception $e)
{

    $fe = \Symfony\Component\Debug\Exception\FlattenException::create($e);

    $statusCode = $fe->getStatusCode();
    $code       = $fe->getCode();
    $message    = $fe->getMessage();

    $errorObj = new \App\LOHDomain\Entities\Error($code, $message);

    return response()->json(['data' => null, 'error' => $errorObj], $statusCode);
}

当我将虚假的 WSDL URL 解析到 SoapClient 时，它会引发两个异常

{"data":null,"error":{"code":"0","message":"SOAP-ERROR: Parsing WSDL: Couldn't load from 'asdsd' : failed to load external entity \"asdsd\"\n"}}
{"data":null,"error":{"code":"1","message":"SOAP-ERROR: Parsing WSDL: Couldn't load from 'asdsd' : failed to load external entity \"asdsd\"\n"}}

所以 json 响应变得无效

在vendor中注释这行代码时，会抛出一个异常：

Laravel\Lumen\Concerns\RegistersExceptionHandlers 特征

protected function registerErrorHandling()
{
        error_reporting(-1);

        set_error_handler(function ($level, $message, $file = '', $line = 0) {
            if (error_reporting() & $level) {
                throw new ErrorException($message, 0, $level, $file, $line);
            }
        });

        set_exception_handler(function ($e) {
            $this->handleUncaughtException($e);
        });

//        register_shutdown_function(function () {
//            $this->handleShutdown();
//        });
}

那么，问题是什么？以及如何在不编辑供应商的情况下解决它？

Answer 1

解决办法是清除最后一个错误，因为它触发了两次。

1. 错误异常。
2. 二是关机功能。

所以，解决办法是：

App\Exceptions\Handler::class

public function render($request, Exception $e)
{

    $fe = \Symfony\Component\Debug\Exception\FlattenException::create($e);

    $statusCode = $fe->getStatusCode();
    $code       = $fe->getCode();
    $message    = $fe->getMessage();

    $errorObj = new \App\Domain\Entities\ResponseEntites\Error($code, $message);

    /**
     * This line of code resolves the issue
     * 
     * To reproduce the issue :
     * 1) Comment this following line of code
     * 2) Provide a fake WSDL URL to the SoapClient
     *
     * Recommendation: Remove this line if you aren't using the SoapClient
     */
    error_clear_last();

    return new \Illuminate\Http\JsonResponse(['data' => null, 'error' => $errorObj], $statusCode);
}

这不是最佳解决方案（但这是我尝试过的最佳解决方案）。 如果您有更好的测试解决方案，请分享。
