perl 访问网站一些useragent的设置

121.40.205.143 - - [22/Jun/2016:12:56:23 +0800] "GET /wechat/account.html HTTP/1.1" 200 3432 "-" "Mozilla/8.0"  --此时地址为haproxy的地址　

120.55.118.6 - - [22/Jun/2016:13:07:26 +0800] "GET /wechat/account.html HTTP/1.1" 200 3432 "-" "Mozilla/8.0"

从wx03-120.55.118.6　访问　
use  LWP::UserAgent;

my $ua = LWP::UserAgent->new;
$ua->timeout(10);
#$ua->env_proxy('http','http://$ARGV[0]');
$ua->agent("Mozilla/8.0");

my $response = $ua->get('https://uatest.xxx.com/wechat/account.html');

if ($response->is_success) {
print $response->decoded_content;  # or whatever
}
else {
die $response->status_line;
}

~

此时useragent为Mozilla/8.0

修改脚本:

use  LWP::UserAgent;

my $ua = LWP::UserAgent->new;
$ua->timeout(10);
#$ua->env_proxy('http','http://$ARGV[0]');
#$ua->agent("Mozilla/8.0");

my $response = $ua->get('https://uatest.xxx.com/wechat/account.html');

if ($response->is_success) {
print $response->decoded_content;  # or whatever
}
else {
die $response->status_line;
}
