perl不在命令提示符下打印特殊字符

标签: html perl encoding command-line special-characters

您好我希望在命令提示符和html文件中打印结果。我在HTML中打印时使用编码(cp1252)但是我无法在命令提示符中看到这些特殊字符,而是获得了一些垃圾值。例如,“£”打印为“ú”。提前致谢

use strict;
use warnings;
use LWP::Simple;
use HTML::TreeBuilder::XPath;
use LWP::UserAgent;

my $competitor_declare='7shop';
my $xpath_declare='//strong';
my @urls = ("http://www.7dayshop.com/delivery-and-returns"); 


open HTML1, '>:encoding(cp1252)',"C:/Users/jeyakuma/Desktop/$competitor_declare.html";
open HTML, '>:encoding(cp1252)',"C:/Users/jeyakuma/Desktop/shipping project/database/$competitor_declare.html";  


foreach my $url (@urls)
        {
        print "\n\nworking on $url\n\n";
        my $ua = LWP::UserAgent->new( agent => "Mozilla/5.0" );
        my $req = HTTP::Request->new( GET => "$url" );
        my $res = $ua->request($req);

        if ( $res->is_success ) 
        {
           print "Please wait while we create file \n\n";
            my $xp = HTML::TreeBuilder::XPath->new_from_url($url);
           my $node = $xp->findnodes_as_string("$xpath_declare") or print "couldn't find the node\n"; #give xpath
            print HTML1 $node and print "Dump file is created please configure the same in xpathconfiguration.pl\n" and print HTML $node;
            print $node;
        }
        else{  
                print "file creation failed\n";

        }
}

命令提示符中的预期输出

cost is - £1.99

当前结果

cost is - ú1.99

7dayshop使用utf8字符集:

<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

在Windows计算机上需要执行两件事,才能在控制台上阅读utf8

  1. 使用以下内容修改您的encoding STDOUT:

    binmode STDOUT, ':utf8:raw';
    
  2. 在运行脚本之前,使用以下命令更改控制台的编码:

    chcp 65001
    
  3. 您可能需要将控制台的字体编辑为Lucida Console之类的字体。

  4. 以下演示了我在Windows机器上的输出:

    use strict;
    use warnings;
    use autodie;
    
    use LWP::Simple;
    use HTML::TreeBuilder::XPath;
    use LWP::UserAgent;
    
    binmode STDOUT, ':utf8:raw';
    
    my $competitor_declare = '7shop';
    my $xpath_declare      = '//strong';
    my @urls               = ("http://www.7dayshop.com/delivery-and-returns");
    
    foreach my $url (@urls) {
        print "\n\nworking on $url\n\n";
        my $ua = LWP::UserAgent->new( agent => "Mozilla/5.0" );
        my $req = HTTP::Request->new( GET => "$url" );
        my $res = $ua->request($req);
    
        if ( $res->is_success ) {
            print "Please wait while we create file \n\n";
            my $xp = HTML::TreeBuilder::XPath->new_from_url($url);
            my $node = $xp->findnodes_as_string("$xpath_declare") or print "couldn't find the node\n";    #give xpath
            print $node;
        }
        else {
            print "file creation failed\n";
        }
    }
    

    输出:

    working on http://www.7dayshop.com/delivery-and-returns
    
    Please wait while we create file
    
    Dump file is created please configure the same in xpathconfiguration.pl
