尝试写一个IRC客户端，但在努力寻找有关规范和连接协议一个很好的资源 [英] Trying to write an IRC client but struggling to find a good resource regarding codes and connection protocol
问题描述
我看了看RFC，但我仍然在挣扎。我写了一个基本的客户在C＃中，但我无法找到如何正确连接文档。
I've looked at the RFC but I am still struggling. I've written a basic client in C# but I cannot find documentation for how to connect properly.
在我连接和发送NICK和用户信息，我需要加入渠道。如果我做了JOIN马上，什么都不会发生 - 大概是因为它是太快了。我不得不推迟，但我不知道是哪个命令我需要等待知道它的好前进
Once I connect and transmit NICK and USER information, I need to join a channel. If I do a JOIN straight away, nothing happens - presumably because it's too soon. I have to delay it, but I don't know which command I need to wait for to know it's okay to go ahead.
我得到的东西，如：
：irc.fish.net注意AUTH：寻找你的主机名...
:irc.fish.net NOTICE AUTH :looking up your hostname...
和
：irc.fish.net 001 FishBot：欢迎
:irc.fish.net 001 FishBot :Welcome
以及东西与代码002，003，005，251，252，等等，但我找不到任何地方上网，显示我这是什么意思
as well as stuff with codes 002, 003, 005, 251, 252, etc. but I can't find anywhere online that shows me what these are.
所以我的基本的2个问题是：你怎么发送响应JOIN和我在哪里可以找到什么上面的IRC码对应？该RFC文件是没用的！
So my basic 2 questions are: What do you send a JOIN in response to, and where can I find what the IRC codes above correspond to? The RFC document was useless!
推荐答案
的RFC文档肯定不是没用！你是正确的，你需要发送 USER 然后按 NICK 。在的通知你得到的是IRC服务器正在试图通过一个称为协议 IDENTD 来连接回您的电脑。这是一个相对简单的协议，但它的结果是，它要知道，在主机上的程序，其连接到服务器，使用该服务器具有本地/远程端口
The RFC documents are certainly not useless! You are correct that you need to send USER followed by NICK. The NOTICE you are getting is that the IRC server is attempting to connect back to your PC via a protocol called IDENTD. It's a relatively simple protocol but the upshot of it is that it wants to know that a program on the host that is connected to the server, is using the local/remote ports that the server has.
有机会，你的防火墙阻止这（和你可能没有运行IDENTD服务器）。这是不是一个巨大的问题，虽然一个不折不扣的IRC客户端将实现它。你可以在这里了解更多。那去到更多的细节。这是比较容易实现。
Chances are, your firewall is preventing this (and you're probably not running an IDENTD server). This is not a huge problem, though a fully-fledged IRC client will implement it. You can find out more here. That goes in to much more detail. It's relatively simple to implement.
大多数IRC服务器会放弃，如果它不能连接到你的，我忘了的确切的副作用这种效应（它已经有一段时间），但你要寻找出下一个消息是MOTD_START / MOTD / MOTD_END和ERR_NOMOTD。只有的之后的你已经收到了当天的邮件的末尾，或者处理的ERR_NOMOTD（没有之一），你可以再使用加入加盟渠道
Most IRC servers will give up if it cannot connect to you, and I've forgotten the exact side-effect of this (it has been a while), but the next messages you want to look out for are the MOTD_START/MOTD/MOTD_END and ERR_NOMOTD. Only after you have received the end of the Message of the day, or handled the ERR_NOMOTD (there isn't one), can you then use JOIN to join channels.
顺便说一句，这是从一个IRC服务器匹配输入一个良好的正则表达式：
Incidentally, this is a good RegEx for matching input from an IRC Server:
^(?:[:@]([^\\s]+) )?([^\\s]+)(?: ((?:[^:\\s][^\\s]* ?)*))?(?: ?:(.*))?$
的IRC RFC文档列表中的所有可能的代码和他们的意思。我不知道为什么你觉得自己很没用。哪些你一直在引用？
The IRC RFCs list all the possible codes and what they mean. I'm not sure why you think they are useless. Which ones have you been referencing?
修改
我抬头一看我的老为IRC C ++代码，所以我可能会多一点帮助。连接后，它进入一个阶段（即我已经标记）的谈判：
I looked up my old C++ code for IRC so I could be a bit more helpful. After connecting, it enters a stage (that I have labelled) negotiating:
谈判阶段：
- 如果一个密码已为服务器指定，发送
PASS输入mypassword。 - 发送
USER命令。 - 输入协商昵称舞台
- 等待
ERR_NOMOTD，END_OFMOTD。直到这些人来，你不是，正式连接
- If a password has been specified for the server, send it
PASS mypassword. - Send the
USERcommand. - Enter the Negotiate Nickname Stage
- Wait for
ERR_NOMOTD,END_OFMOTD. Until one of these comes, you're not "officially connected".
协商昵称阶段：
这是完全可能的连接时，您要使用的昵称已在使用。因此，客户端应该：
It's entirely possible that during connection, the nickname you want to use is already in use. Therefore the client should:
- 发出
NICK命令 - 如果您收到
ERR_NICKINUSE响应，再次发出它。如果你没有更多的昵称使用，您可以救助或提示用户换一张
- Issue a
NICKcommand - If you receive a
ERR_NICKINUSEresponse, issue it again. If you have no more nicknames to use, you can either bailout or prompt the user for another one.
其他的一些事情需要考虑：
Some other thing to consider:
- 查找我们对
PING命令。当你空闲的服务器将发送这一点。处理这种高优先级，并返回PONG与服务器给你的数据。如果不这样做将确保你得到切断，并且当你正在测试一个IRC客户端，这可以在追尾一种痛苦。
- Look our for the
PINGcommand. The server will send this when you're idle. Handle this as high-priority and returnPONGwith the data the server gave you. Failure to do this will ensure you get disconnected and when you're testing an IRC client, this can be a pain in the rear-end.
奖金玩转
这是我对IRC命令枚举，你应该可以把这个到C＃轻松就够了：
