我需要编写一小段代码来模拟来自不同源IP地址的流量,我想知道是否可以通过使用Perl欺骗地址来实现这一点？
我尝试过Net :: RAWIP,但是我需要发送一些更复杂的HTTP流量(即POST数据),但无法使用RAWIP
使用LWP我尝试使用ua> local_address,但我得到了这个回复：
Can't connect to 10.x.x.x:8080 LWP::Protocol::http::Socket: Cannot assign requested address at /usr/lib/perl5/site_perl/5.10.0/LWP/Protocol/http.pm line 51.
这是我正在使用的代码：
#!/usr/bin/perl -w
use strict ;
use warnings ;
use LWP::UserAgent ;
use URI::URL ;
my $path = 'http://142.133.114.130:8080' ;
my $url = new URI::URL $path;
my $ua = LWP::UserAgent->new();
$ua->local_address('10.121.132.112');
$ua->env_proxy ;
my $effing = 'blaj.jpg' ;
my $response = $ua->post( $url,'Content-Type' => "multipart/form-data",'Content' => [ userfile => ["$effing" ]],'Connection' => 'keep-alive' ) ;
print $response->decoded_content();
解决方法
如果您从不属于您的地址发送,则无法获得回复.这意味着您所能做的就是发送请求.您已经表明可以进行发送,因此您只需要发送请求即可.这很简单.
use strict;
use warnings;
use HTTP::Request::Common qw( POST );
my $req = POST('http://www.example.org/','Content' => [ userfile => [ $0 ]],'Connection' => 'keep-alive',);
print $req->as_string();
输出：
POST http://www.example.org/
Connection: keep-alive
Content-Length: 376
Content-Type: multipart/form-data; boundary=xYzZY
--xYzZY
Content-Disposition: form-data; name="userfile"; filename="x.pl"
Content-Type: text/plain
use strict;
use warnings;
use HTTP::Request::Common qw( POST );
my $req = POST('http://www.example.org/',);
print $req->as_string();
--xYzZY--
