Question

我有一个php脚本加入这个IRC服务器上的频道：irc.worldnet.net 由于服务器响应，我可以说我成功加入了频道，并且僵尸程序在用户列表中。但是，这个命令：

MSG bot_nickname hello my friend !

发出'msg：unknown命令'响应。当我发送这一行时：

PRIVMSG bot_nickname : hello my friend !

机器人没有响应（我还没有任何错误消息）。我发送的命令有问题吗？

这是我使用的php代码：

<?php

$channel_sent = false;
$channel_joined = false;
$msg_sent = false;
set_time_limit(0);
ini_set('display_errors', 'on');

$config = array(
    'server' => 'irc.worldnet.net',
    'port' => 6667,
    'nick' => 'cesame'.rand(),
    'channel' => '#nc-irc-challs'
);

$server = array();
$server['SOCKET'] = @fsockopen($config['server'], $config['port'], $errno, $errstr, 2); 

if($server['SOCKET'])
{
    SendCommand("PASS NOPASS\n\r");
    SendCommand("NICK " . $config['nick'] . "\n\r"); 
    SendCommand("USER " . $config['nick'] . " USING PHP IRC\n\r");    
    SendCommand("JOIN " . $config['channel'] . "\n\r");

    while(!feof($server['SOCKET'])) {
            ReadServer();
            flush();
            sleep(1);
    }
}

function ReadServer(){
    global $server;
    global $config;
    global $channel_joined;
    global $channel_sent;
    global $msg_sent;
    $server['READ_BUFFER'] = fgets($server['SOCKET'], 1024);
    echo "[RECEIVE] ".$server['READ_BUFFER']."<br>\n\r";  

    if(substr($server['READ_BUFFER'], 0, 6) == "PING :") { 
        SendCommand("PONG :".substr($server['READ_BUFFER'], 6)."\n\r"); 
    }
    if(strpos($server['READ_BUFFER'], "#nc-irc-challs :End of /NAMES list")){
        $channel_joined = true;
    }
    if(trim($server['READ_BUFFER']) == "" && $channel_joined &&!$msg_sent) {
        SendCommand('PRIVMSG Daneel : .challenge_caesar start' . "\n\r");
        $msg_sent = true;
    }
}

function SendCommand ($cmd)
{
    global $server; //Extends our $server array to this function
    @fwrite($server['SOCKET'], $cmd, strlen($cmd)); //sends the command to the server
    echo "[SEND] $cmd <br>"; //displays it on the screen
} 

?>

所以我跟着你的建议。这是我得到的日志：

Answer 1

IRC服务器通常不会发送空字符串。

如果你想要在BOT进入频道后发出命令，你应该在你知道它在/NAMES列表末尾的频道中，或者一旦发送时发送它您收到TOPIC。

此外，PRIVMSG的语法如下：

PRIVMSG <NICKNAME> :<MESSAGE>

:之后没有空格。如果接收端设置为响应.command但得到 .command，则可能是问题所在。

发送私人讯息给IRC机器人
