apache - 为什么在梅森处理程序打印标准页面中使用 $r->print？

Question

当我在 HTML::Mason::ApacheHandler 中做

sub handler {
    my ($r) = @_;

    $r->content_type('text/plain');
    $r->print( 'YES' );

    $r->log_error( $r->bytes_sent );

    return 200;
}

我得到页面：

OK

The server encountered an internal error or misconfiguration and was unable to complete your request.

Please contact the server administrator, [no address given] and inform them of the time the error occurred, and anything you might have done that may have caused the error.

More information about this error may be available in the server error log.
Apache/2.2.22 (Debian) Server at localhost Port 443

如何将“YES”打印到浏览器？

Answer 1

我必须添加use Apache2::RequestIO;到我的 handler.pl

当出现问题时，我必须更加专心并检查 /var/log/apache2/error.log。

要使用自定义页面进行响应，我可以使用 custom_response

sub handler {
  my ($r)=@_;
  @{$r->pnotes}{qw/etext ect/}=("sorry, no access\n", 'text/plain; charset=my-characters');
  $r->custom_response( 403, "/-/error" );
  return 403;
}
