Python twisted irc - 登录时的服务器密码

Posted 2023-02-23

【中文标题】Python twisted irc - 登录时的服务器密码

【英文标题】：Python twisted irc - server password on login

【发布时间】：2014-05-24 21:40:14

【问题描述】：

我正在尝试使用 Twisted 在 Python 中创建一个简单的 IRC 机器人。我已经走了很远，但是当我需要提供密码才能进入服务器时遇到了问题。

我知道如何实现加入特定频道的密码，但我不知道如何在加入 IRC 服务器本身时提供用户名和密码。

我需要提供密码的原因是我希望机器人与保镖兼容 (ZNC)。

（请原谅糟糕的缩进）

这是我目前尝试过的

我在 Twisted 文档中找不到任何关于服务器密码的信息，只有频道密码。非常感谢任何帮助！

【参考方案1】：

看看

http://twistedmatrix.com/documents/current/api/twisted.words.protocols.irc.IRCClient.html

我注意到属性password，带有描述：

password =
    Password used to log on to the server. May be None. 

在我看来，您可以在Bot 类上设置密码属性，因此

class Bot(irc.IRCClient):
    def _get_nickname(self):
        return self.factory.nickname

    nickname = property(_get_nickname)
    password = "PASSWORD"

    ...

这有意义吗？它有效吗？

一切顺利:)

【讨论】：

刚试了一下，好像不行。 :( 我没有收到任何错误消息，连接只是超时或什么的。

应该可以！刚刚查看了 IRCClient 的源代码github.com/twisted/twisted/blob/trunk/twisted/words/protocols/… 查看函数register 和connectionMade。正如我所看到的，实现符合 rfc1459（IRC，tools.ietf.org/html/rfc1459.html）第 4.1 节描述连接注册，所以我认为你的问题出在其他地方。

你的 IRC 服务器日志说什么？

我无权访问服务器日志，所以我无法检查...不幸的是我没有弄清楚：/它没有抛出任何异常，我只是得到这个：“失败实例：回溯（无帧失败）：：连接已完全关闭。”大约 5 分钟后

我刚看了你的代码，有些东西很不对劲，你似乎没有理解协议和协议工厂之间的关系。感觉就像你有点过头了。我为您编写了一个小脚本，请根据您的需要调整带有大写字母的变量并运行它。请发布输出。然后我会尽力帮助你。 gist.github.com/brunsgaard/6c9d3f2c6dd344180430
