为什么在梅森处理程序打印标准页面中$r>打印？

Question

当我在HTML::Mason::ApacheHandler

sub handler {
    my ($r) = @_;
    $r->content_type('text/plain');
    $r->print( 'YES' );
    $r->log_error( $r->bytes_sent );
    return 200;
}

I get page:

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

如何打印'YES'到浏览器?

Answer 1

我必须添加use Apache2::RequestIO;到我的处理程序。pl

当出现问题时，我必须更加注意并检查/var/log/apache2/error.log。

为响应使用自定义页面，我可以使用custom_response

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