我在发送命令和从我设置的telnet连接接收文本/数据时遇到了一些麻烦 .
#!perl
#Telnet.pl
use Net::Telnet;
# Create a new instance of Net::Telnet,
my $telnetCon = new Net::Telnet (Timeout => 20,
Dump_Log => "dump.log",
Input_Log => "infile.log",
Output_log => "output.log",
Prompt => '/\$ $/') or die "Could not make connection.";
# Connect to the host of the users choice
$telnetCon->open('');
#get username and password from user
my $CXusername = '';
my $CXpassword = '';
my $task = '50104'; # Get this input from the search
# Recreate the login
# Wait for the login: message and then enter the username
$telnetCon->waitfor(match => '/login:/i');
# this method adds a \n to the end of the username, it mimics hitting the enter key after entering your username
$telnetCon->print($CXusername);
$telnetCon->waitfor(match => '/Password:/i');
# does the same as the previous command but for the password
$telnetCon->print($CXpassword);
#Wait for the login successful message
$telnetCon->waitfor(match => '/$/');
$telnetCon->cmd("viewtask 50104");
$telnetCon->cmd(" ");
$telnetCon->cmd(" ");
@output = $telnetCon->cmd("who");
print @output;
($output) = $telnetCon->waitfor(match => '/$/');
print "Output: ",$output;
if($searched =~ /MODIFIED files in Task $_[1] :(.*?)The/s){
# to Logout of the telnet connection
$telnetCon->print("exit");
#return the modified data
return $1;
}
告诉我,如果问题没有't make sense, I' ll尝试重新编写它 .
所以这是telnet视图 . 当我输入$ telnetCon-> cmd(“viewtask 50140”)时,我卡在第一张图像上 . 我想进入第二个图像并继续在我的telnet会话中输入命令 .

Net::Telnet
cmd
方法写入您的命令(附加\n
)并等待提示 . 这与您的程序等待输入完成输出不兼容 .我认为在你的情况下你会想要使用
print
和getlines
和/或waitfor
的组合来使这个工作
