try/catch 无法处理异常

Question

我正在使用 Goutte (which uses Guzzle) 提取内容，但我的脚本以错误结尾，尽管我在 try/catch:

中运行

Error: Client error: `GET http://example.com/C42C9CA3` resulted in a `403 Forbidden` response:
<?xml version="1.0" encoding="iso-8859-1"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
         "htt (truncated...)

这是我的：

use Goutte\Client;
$HTTPconfig = [ "curl" => [
                  CURLOPT_TIMEOUT => 60,
                  CURLOPT_CONNECTTIMEOUT => 60,
                  CURLOPT_SSL_VERIFYPEER => false,
                ],
                ['http_errors' => false]
              ];
$HTTPclient = new \Goutte\Client;
$HTTPclient->setClient(new \GuzzleHttp\Client($HTTPconfig));
$HTTPclient->setHeader('user-agent', 'Mozilla/5.0 (Windows NT 6.2; rv:20.0) Gecko/20121202 Firefox/20.0');

try {
  $crawler = $HTTPclient->request('GET', $url);
  $doc = $crawler->html();
} catch (Exception $e) {
  write($e->getMessage());
  continue;
}

Answer 1

删除 ['http_errors' => false] 选项。默认为 true，结果为 4xx/5xx 响应代码除外。

Answer 2

试试：

  } catch (\Exception $e) {

而不是：

  } catch (Exception $e) {

编辑：

如果您使用的是 PHP-7，您可以尝试使用斜杠来捕捉 Throwable，如下所示：

  } catch (\Throwable $e) {
