連接到IRC服務器的問題

Question

最近一直在努力創建IRC bot，雖然它似乎連接&與大多數IRC服務器一起工作，但似乎與Twitch IRC服務器（irc.twitch.tv）有關。

當連接到另一臺服務器時，收到的數據&沒有發出任何問題，但是使用twitch連接時，我無法發送或接收數據。

初始化：

Connection::Connection(char* server, int port, std::string nick, std::string pass) 
{ 
    fServer = server; 
    fPort = port; 
    fNick = nick; 
    fPass = pass; 
    fChanCount = 0; 

    clear_buffer(); 

    fSock = socket(AF_INET, SOCK_STREAM, IPPROTO_TCP); 

    cout << "Attempting to resolve host: " << fServer << endl; 
    fHost = resolve_host(fServer); 
    fSaddr.sin_addr.S_un.S_addr = fHost; 
    fSaddr.sin_port = htons(fPort); 
    fSaddr.sin_family = AF_INET; 

    cout << "Resolved to: " << fHost << endl; 
} 

打開連接：

int Connection::Connect() 
{ 
    if (connect(fSock, (sockaddr*)&fSaddr, sizeof(fSaddr)) == SOCKET_ERROR) 
    { 
     cout << "Can't connect to " << fServer << endl; 
     return 0; 
    } 

    recv(fSock, fBuffer, 1024 * 8, 0); 

    cout << fBuffer << endl << endl << flush; 

    send_message("PASS " + fPass); 
    send_message("NICK " + fNick); 
    send_message("USER " + fNick + " 0 * :" + fNick); 

    return 1; 
} 

清除緩衝區：

void Connection::clear_buffer() 
{ 
    memset(fBuffer, 0, sizeof(fBuffer)); 
} 

接收：

string Connection::receive_message() 
{ 
    clear_buffer(); 

    recv(fSock, fBuffer, 1024 * 8, 0); 

    return fBuffer; 
} 

如果需要，可能會造成這種情況，可能會提供更多細節。

你的用戶信息看起來並不像什麼RFC2812規範的要求。

3.1.3 User message 

     Command: USER 
    Parameters: <user> <mode> <unused> <realname> 

    The USER command is used at the beginning of connection to specify 
    the username, hostname and realname of a new user. 

    The <mode> parameter should be a numeric, and can be used to 
    automatically set user modes when registering with the server. This 
    parameter is a bitmask, with only 2 bits having any signification: if 
    the bit 2 is set, the user mode 'w' will be set and if the bit 3 is 
    set, the user mode 'i' will be set. (See Section 3.1.5 "User 
    Modes"). 

    The <realname> may contain space characters. 

    Numeric Replies: 

      ERR_NEEDMOREPARAMS    ERR_ALREADYREGISTRED 

    Example: 

    USER guest 0 * :Ronnie Reagan ; User registering themselves with a 
            username of "guest" and real name 
            "Ronnie Reagan". 

    USER guest 8 * :Ronnie Reagan ; User registering themselves with a 
            username of "guest" and real name 
            "Ronnie Reagan", and asking to be set 
            invisible. 

也許這就是導致問題的原因？

否則，我已經發現了一些服務器需要在PASS消息的密碼，即使服務器未配置爲要求之一。在這些情況下，我發送：

PASS none
