use Encode;  
use Encode::CN;  
use URI::Escape;  
use LWP::Simple;  
#$host = "http://ip.taobao.com/service/getIpInfo.php?ip=202.101.172.35";  
#$host = "https://user.95516.com/uc-cdhd-web/rest/reg/sendmobilecaptcha/?mobile=177xx805&msgType=01";  
$host = "http://licai.yingyinglicai.com/user/smsVerifySend.do?mobile=17xx07805";  
$content = get($host);  
print "$content is $contentn";

可以发短信成功:



[root@master ~]# cat y2.pl 
use Encode;  
use Encode::CN;  
use URI::Escape;  
use LWP::Simple;  
#$host = "http://ip.taobao.com/service/getIpInfo.php?ip=202.101.172.35";  
$host = "https://user.95516.com/uc-cdhd-web/rest/reg/sendmobilecaptcha/?mobile=180xx22237&msgType=01";  
#$host = "http://licai.yingyinglicai.com/user/smsVerifySend.do?mobile=17xx6507805";  
$content = get($host);  
print "$content is $contentn";
[root@master ~]# perl y2.pl 
$content is
