由于工作需要,最近一年一直在研究和使用C#,加上最近工作上有做微信机器人的需要,在已经对接、调试稳定之后,将项目的源码分享给大家,传递开源精神。
1、开发工具:Vistual Studio 2022
2、NetFramework版本:6.0及以上
3、微信版本:WeChatSetup_3.7.0.30.exe (找不到可以私信我)
目前该组件自身支持很多功能,如下所示:
在这些功能的基础上我们可以结合自身的使用场景进行定制化开发和调用。目前我主要根据群聊中@和私聊这两个场景进行一些封装,我将代码进行了删减,仅保留基础部分。
项目整体有三个部分构成。如下图所示:
ConsoleApp1用于自定义逻辑和启动类都写在中。–自行创建
RS.Snail.JJJ.Wechat是底层依赖组件。–可参考我上传的附件
Segments是自带中文分词器的一个组件,用于对用户问题与问题列表进行分词匹配。–下篇文章详解
启动类实现代码 Program.cs 代码如下
// See https://aka.ms/new-console-template for more information
using ConsoleApp1;
using Newtonsoft.Json.Linq;
using RS.Snail.JJJ.Wechat;
using static ConsoleApp1.MessageHandler;
Console.WriteLine("Hello, World!");
var wechat = new RS.Snail.JJJ.Wechat.Service();
String mSelf_WXID = "wxid_m2khoia398xh22";//登录
bool v = wechat.Init(
// new List<string> { "wxid_1234_" },
new List<string> { mSelf_WXID },
new Func<dynamic, Task>((msg) => {
Console.Write(msg);
;
//CDATA[,wxid_8qfg0x0do56t22
MessageParam mMessageParam = new MessageParam(mSelf_WXID,wechat, (JObject)msg);
if (mMessageParam.isAtSelf())//判断是否是群聊@微信机器人
{
List<String> atPersons = mMessageParam.getAtList();
String mTemp = ((JObject)msg).GetValue("message").ToString();
foreach (String mItem in atPersons) {
String mOld = "@" + wechat.ChatroomGetMemberNick(mSelf_WXID, ((JObject)msg).GetValue("sender").ToString(), mItem);
mTemp = mTemp.Replace("@微信客服", "").Trim();//注意,这里需要与自身微信昵称保持一致
}
ThreadParam mThreadParam = new ThreadParam() {
ObjParam = wechat,Msg=msg, MTemp=mTemp, Self_WXID=mSelf_WXID
};
new Thread(new ParameterizedThreadStart((Obj) =>
{
new MessageHandler().sendAnswer((ThreadParam)Obj);
})).Start(mThreadParam);
}
else {
String mTemp = ((JObject)msg).GetValue("message").ToString();
List<String> atPersons = mMessageParam.getAtList();
ThreadParam mThreadParam = new ThreadParam()
{
ObjParam = wechat,
Msg = msg,
MTemp = mTemp,
Self_WXID = mSelf_WXID
};
new Thread(new ParameterizedThreadStart((Obj) =>
{
new MessageHandler().transferAnser((ThreadParam)Obj);
})).Start(mThreadParam);
}
return new Task(new Action(() => {
}));
})
//msg => Console.Write(msg)
) ;
//图片保存钩子
//wechat.MsgStartImageHook(mSelf_WXID, "D:\\image");
wechat.StartReceive();
Console.ReadKey();

CommonUtils.cs由于都是一些发送http请求的方法,就不放源码了,大家自行实现。
首先需要配置启动项,我们需要将ConsoleApp1配置为启动项。
启动项目后会自动打开一个控制台,同时唤醒微信客户端。
需要扫码登录后,在控制台中输入大写的Y,即可完成登录。
这里由于我的微信自动升级了版本,就不演示了。
当你在群聊中@微信机器人时,就会按照代码中的实现逻辑自动回复你了。这其中的语料库可以自己通过查库,本地读取,或者直接接入目前主流的各类大语言模型(chatGPT,文心一言,通义千问,科大星火等等),发挥自己的想象力,尽情的尝试吧。
