我有下面的代码片段，它使用从另一个perl程序收集的cookie，通过perl模块LWP：：UserAgent登录到sharepoint网站。

use strict;
use warnings;
use LWP::UserAgent;
use HTTP::Request::Common;
use HTTP::CookieJar::LWP ();
use HTTP::Cookies;

my $resultXML='C:\Docs\Result.txt';
my $url="https://[mydomain].sharepoint.com/_api/contextinfo";
        
my $cookie_jar_obj = HTTP::Cookies->new();
$cookie_jar_obj->load( $resultXML );
my $lwp = LWP::UserAgent->new();
$lwp->cookie_jar( $cookie_jar_obj ); 
        
print $lwp->cookie_jar->as_string() . "\n";

my $response = $lwp->request(POST $url);
print $response->content . "\n";

其中存储在变量$resultXML中的文件包含以下Cookie信息：

#LWP-Cookies-1.0

如果我从"rtFA ="部分开始将此信息复制并粘贴到"Advanced REST client" chrome扩展中，我会得到成功的响应。
但是在打印条目时

$lwp->cookie_jar->as_string()

在结果中有额外的双引号字符。

如果我复制并粘贴此信息，同样，从"rtFA ="部分开始到"Advanced REST client" chrome扩展中，我会得到错误403 Forbidden error，这正是我在

声明。
我怎样才能阻止perl插入这些额外的双引号（"）标记，这些标记似乎阻止了我的perl脚本连接到网站？
