Question

首先，我的英语不是最好的，谢谢你的理解。

代码主体index.cgi的一部分

my ($url, $params) = split(/\?/, $ENV{'REQUEST_URI'}); 
my @pairs = split(/&/, $params);

foreach $pair (@pairs) {

    my ($name, $value) = split(/=/, $pair);
    $value =~ tr/+/ /;
    $value =~ s/%([a-fA-F0-9][a-fA-F0-9])/pack("C", hex($1))/eg;
    $PARAM{$name} = $value;
}
my $consulta = $PARAM{'buscar'};

print CGI::header();
print qq{<div style="font-family: monospace">\n};
$mysqltest->buscar($consulta);
print "\n<br /><br />\n";
print "\n</div>\n";

模块搜索和结果以cgi打印 - ＆gt;的index.cgi

sub buscar{
    my $self = shift;
    my $keyword = shift;

    die "not work" if not $self->{mysqlopen};

    my $queryKeyword = $self->{connect}->prepare("SELECT * FROM savebookmarks WHERE MATCH (url,descripcion) AGAINST ('$keyword');");
    $queryKeyword->execute();

    while (my $resultKeyword = $queryKeyword->fetchrow_hashref()) {

        print dumper_html("$resultKeyword->{id} $resultKeyword->{descripcion} $resultKeyword->{url}");
    }
    $queryKeyword->finish();
    return;
}

index.cgi中的结果打印输出

...
$VAR1 = 'The Python Standard Library â€” Python v2.7.2 documentation http://docs.python.org/library/';
$VAR1 = 'python-nmap : using nmap from python http://xael.org/norman/python/python-nmap/';
$VAR1 = 'Manejo de Excepciones en Python Â« Tutorial Python http://tutorial-python.com.ar/?p=193';
$VAR1 = 'FAQ\'s de Python - Foros del Web http://www.forosdelweb.com/f130/faqs-python-591053/#post2533652';
...

我遇到或无法解决的问题是，查询的印象添加了 $ VAR1 =＆＃39; （它不应该）影响结果，有人要解决它吗？

这是我需要的完美输出。 - ＆GT;
