如何使用 perl 模块 LWP::UserAgent 指定存储在文件中的 cookie

Question

我有以下一段代码，它使用从另一个 perl 程序收集的 cookie 使用 perl 模块 LWP::UserAgent 登录到共享点网站。

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";

存储在变量$resultXML中的文件包含以下cookie信息：

#LWP-Cookies-1.0
Set-Cookie3:rtFa=UROIhi84Sxr8o0DZHximQjlCOUI2QzItMzRDMC00N0Q1LTgyQ0EtMzI1MzhCRjNERTZDjQiIQbx0/QTRCNtpvjQTaZEcjpYFSkKHsPK+d1Nlnx6MuaDI/Xs21W7orysOeYPRRoDCCX/3ZtL61T3SHYfMkPeqXTJ4rloliGHsN7tuQXeI6OYAXXs8ysayP4VzpJyQEm+S0zvjkVLLtanQ5RDfQ1bnYq9ayu7L5HDJDNaKQhmhXmTdodwTlvwJRRyWgLL/GCuWWyAXEppy9Ta7PzpO76sb9c91ssScjDJY/Fw7TIPipleMgjjnHud1Os/NAihtTxTMWxS5XpiZbCh6DtvPwYyZXE54nsyhIekRvrixFQ0PeZinWpAkUAAAA=; domain=sharepoint.com; path=/; SameSite=None; secure; HttpOnly;FedAuth=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; path=/; SameSite=None; secure; HttpOnly;

如果我从“rtFA=”部分开始将此信息复制并粘贴到“高级 REST 客户端”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()

结果中有多余的双引号字符。即

如果我再次复制并粘贴此信息，从“rtFA=”部分开始到“高级 REST 客户端”chrome 扩展程序中，我会收到错误 403 Forbidden 错误，这正是我在运行其余部分时得到的之后的代码

打印 $lwp->cookie_jar->as_string() 。 "\n";

声明。

如何阻止 perl 插入这些似乎阻止我的 perl 脚本连接到网站的额外双引号 (") 标记？

Answer 1

不要使用as_string 的结果来获取cookie 值。这通常不适用于电线。查看HTTP::Cookies 中的add_cookie_header 子例程，并注意他们不使用as_string 来找出任何东西。这确实引用了除值之外的所有内容。

我认为你需要考虑的第一件事是你给HTTP::Cookies 提供了什么。也许变量名中的XML 只是一个坏名字，但数据不是XML。如果你弄乱了 Result.txt 中的数据，你的问题很早就出现了：

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 );
