Facebook分享按钮不会分享符号

Question

我在这里尝试了这段代码来共享我所在的当前页面，但是一些url是关闭的，所以它共享了错误的页面。我计算出符号"&“被剪掉了，所以我想知道是否有人知道如何绕过它。

代码：

<a target="_blank" href="http://www.facebook.com/sharer/sharer.php?u=http://www.ibidthai.com/auction.pl?category=$form{'category'}&item=$form{'item'}">Share</a>

$form{'category'}和$form{'item'}是一个变量，在本例中是它的category="car“和item="[]1415689774”

Answer 1

您需要使用URI::Escape或一些类似的模块/功能来转义查询参数：

use strict;
use warnings;

use URI::Escape;

my %form = ( category => 'car', item => '[]1415689774' );

my $u = "http://www.ibidthai.com/auction.pl?category=$form{'category'}&item=$form{'item'}";

my $url = "http://www.facebook.com/sharer/sharer.php?u=" . uri_escape($u);

print "$url\n";

输出：

http://www.facebook.com/sharer/sharer.php?u=http%3A%2F%2Fwww.ibidthai.com%2Fauction.pl%3Fcategory%3Dcar%26item%3D%5B%5D1415689774

但是，如果您想要彻底，如果第一个URI的查询参数可能包含特殊字符，则两个URI实际上都应该进行编码：

use strict;
use warnings;

use URI;

my %form = ( category => 'car', item => '[]1415689774' );

my $auction_uri = URI->new("http://www.ibidthai.com/auction.pl");
$auction_uri->query_form( category => $form{category}, item => $form{item} );

print "$auction_uri\n";

my $share_uri = URI->new('http://www.facebook.com/sharer/sharer.php');
$share_uri->query_form( u => "$auction_uri" );

print "$share_uri\n";

输出：

http://www.ibidthai.com/auction.pl?category=car&item=%5B%5D1415689774
http://www.facebook.com/sharer/sharer.php?u=http%3A%2F%2Fwww.ibidthai.com%2Fauction.pl%3Fcategory%3Dcar%26item%3D%255B%255D1415689774
