AnyEvent学习之2 -并行ping
发布时间：2020-12-16 00:21:00 所属栏目：大数据 来源：网络整理
导读：这个例子是参照CU flw斑竹的抓网页例子写的异步并行ping的例子。 使用了Anyevent::ping模块。（这个比较简单） 很奇怪，Anyevent::FastPing 模块怎么也无法正确运行。（功能太复杂，需要分析源码，还有c代码） ?? 后记:发现是例子 问题,按照test用例写就ok了

这个例子是参照CU flw斑竹的抓网页例子写的异步并行ping的例子。 使用了Anyevent::ping模块。（这个比较简单） 很奇怪，Anyevent::FastPing 模块怎么也无法正确运行。（功能太复杂，需要分析源码，还有c代码） ?? 后记:发现是例子 问题,按照test用例写就ok了.不过FastPing用法有些特别. 先看看ping模块的例子 use AnyEvent;
use AnyEvent::Ping;
my $c = AnyEvent->condvar;
my $ping = AnyEvent::Ping->new;
$ping->ping('google.com',1,sub {
my $result = shift;
print "Result: ",$result->[0][0]," in ",$result->[0][1]," secondsn";
$c->send;
});
$c->recv;
注意，cv的方法不同，具体的不同点还需要看文档。 运行需要root权限 ? use AnyEvent;
use AnyEvent::Ping;
my $cocurrent = 100; # 并发数
my @todoList = map { "192.168.6." . $_ } (1 .. 254); #
my $cv = AnyEvent->condvar;
my $ping = AnyEvent::Ping->new;
doit() foreach 1..$cocurrent;
sub doit{
my $ip = shift @todoList;
return if not defined $ip;
$cv->begin;
$ping->ping($ip,sub{ done( $ip,@_ ) } );
}
sub done {
my ($ip,$result) = @_;
$cv->end();
print "Result($ip): "," secondsn";
doit();
}
$cv->recv();
?运行结果如下,可以看到是并行运行的，通的ip很快返回了结果 ?-bash-3.00# perl testping5.pl Result(192.168.6.21): OK in 0.0064699649810791 seconds Result(192.168.6.17): OK in 0.00709700584411621 seconds Result(192.168.6.26): OK in
