ItChat4JS

ItChat4JS -- 用NodeJs扩展个人微信号的能力

ItChat是一个非常优秀的开源微信个人号接口,使用Python语言开发,提供了简单易用的API,可以很方便地对个人微信号进行扩展,实现自动回复,微信挂机机器人等。 通过阅读和学习ItChat python源码,通过NodeJs完成了一个JS版本,由于主要灵感来源于itchat项目,所以这个项目的就暂时定名为ItChat4JS吧。

安装

可以通过本命令安装ItChat4JS:

npm install itchat4js

重要更新---2021-11-05

桌面版本微信 hack某些微信号天生无法网页登录的缺陷

    // 启动的时候只需要增加desktopMode为true即可
    itChat4JsIns.login({ desktopMode: true});

或者

    // 启动的时候只需要增加desktopMode为true即可
    itChat4JsIns.run({ desktopMode: true});

简单入门实例

有了ItChat4JS,如果你想要给文件传输助手发一条信息,只需要这样:

import ItChat4JS, { sendTextMsg } from 'itchat4js';

const itChat4JsIns = new ItChat4JS();

const doFn = async () => {
    await itChat4JsIns.login();
    await sendTextMsg('Hello FileHelper', 'filehelper');
};

doFn();

如果你想要回复发给自己的文本消息,只需要这样:

import ItChat4JS, { sendTextMsg, EMIT_NAME, MESSAGE_TYPE  } from 'itchat4js';

const itChat4JsIns = new ItChat4JS();

itChat4JsIns.listen(EMIT_NAME.FRIEND, MESSAGE_TYPE.TEXT, async (msgInfo, toUserInfo) => {
    const { text } = msgInfo;
    const { UserName } = toUserInfo;
    sendTextMsg(text, UserName)
});

itChat4JsIns.run();

消息来源分类

import { EMIT_NAME } from 'itchat4js';
console.log('消息来源分类', EMIT_NAME)

FRIEND:来自于微信好友的消息 CHAT_ROOM:来自于群聊的消息 MASSIVE_PLATFORM:来自于公众号、订阅号的消息

消息类型分类

import { MESSAGE_TYPE } from 'itchat4js';
console.log('消息类型分类', MESSAGE_TYPE)

TEXT:文本消息 MAP:地图、位置消息 CARD:名片 NOTE:笔记 SHARING:分享 PICTURE:图片 RECORDING: VOICE:语音 ATTACHMENT:附件文件 VIDEO:视频 FRIENDS:添加好友申请 SYSTEM:系统消息

各类型消息的注册

import ItChat4JS, { sendTextMsg, EMIT_NAME, MESSAGE_TYPE  } from 'itchat4js';

const itChat4JsIns = new ItChat4JS();

const msgArr = [
    MESSAGE_TYPE.TEXT,
    MESSAGE_TYPE.PICTURE,
    MESSAGE_TYPE.FRIENDS,
    MESSAGE_TYPE.VIDEO,
];

itChat4JsIns.listen(EMIT_NAME.FRIEND, msgArr, async (msgInfo, toUserInfo) => {
    const { text, type, download } = msgInfo;
    if (type === MESSAGE_TYPE.PICTURE) {
        await download('download/friend/image');
    } else if (type === MESSAGE_TYPE.FRIENDS) {
        const { status, verifyContent, autoUpdate: { UserName } } = text;
        itChat4JsIns.verifyFriend(UserName, status, verifyContent)
    } else if (type === MESSAGE_TYPE.TEXT) {
        console.log(text)
    } else if (type === MESSAGE_TYPE.VIDEO) {
        await download('download/friend/video');
    }
});

itChat4JsIns.run();

常用的方法及使用

实例方法

1.登录 async itChat4JsIns.login()

异步方法,用户扫码登录,receiving:是否自动接收消息,默认false

import ItChat4JS from 'itchat4js';

const itChat4JsIns = new ItChat4JS();

const doFn = async () => {
    await itChat4JsIns.login();
};

doFn();

2.监听消息 listen(emitName, msgType, callback)

emitName:消息来源,参见EMIT_NAME msgType: 消息类型,MESSAGE_TYPE。可以是string也可以是Array,也可以undefined或null callback:处理消息的实际操作

callback参数:msgInfo, toUserInfo msgInfo:经过处理之后的消息信息,包含: text:文本内容 type:消息信息 filename:文件名 async download(path='', filename='', toStream=false):下载 download 异步下载,可以指定下载路径和文件名。path不传,会以项目根路径为目录下载,filename不传会自动生成,下载之后不保存,以stream的形式返回,默认值false(目前还不支持)

import ItChat4JS, { sendTextMsg, EMIT_NAME, MESSAGE_TYPE  } from 'itchat4js';

const itChat4JsIns = new ItChat4JS();

itChat4JsIns.listen(EMIT_NAME.FRIEND, MESSAGE_TYPE.TEXT, async (msgInfo, toUserInfo) => {
    const { text } = msgInfo;
    const { UserName } = toUserInfo;
    sendTextMsg(text, UserName)
});

itChat4JsIns.run();

3.好友添加及验证 async verifyFriend(userName, status = 2, verifyContent = '', verifyUserTicket = '', autoUpdate = true)

userName:申请加好友的UserName status: 操作类型,默认值为2。2:添加好友,3:验证好友申请 verifyContent:添加和被添加的验证内容 verifyUserTicket: 用户的ticket autoUpdate:是否更新本地好友信息,默认值为true

import ItChat4JS, { EMIT_NAME, MESSAGE_TYPE  } from 'itchat4js';

const itChat4JsIns = new ItChat4JS();

itChat4JsIns.listen(EMIT_NAME.FRIEND, MESSAGE_TYPE.FRIENDS, async (msgInfo, toUserInfo) => {
    const { text } = msgInfo;
    const { status, verifyContent, autoUpdate: { UserName } } = text;
    itChat4JsIns.verifyFriend(UserName, status, verifyContent)
});

itChat4JsIns.run();

4.通过UserName,NickName或者RemarkName获取好友信息 getContactInfoByName(name)

name:UserName或者NickName

import ItChat4JS from 'itchat4js';

const itChat4JsIns = new ItChat4JS();

const doFn = async () => {
    await itChat4JsIns.login();
    console.log(itChat4JsIns.getContactInfoByName('xxx'));
};

doFn()

5.设置好友备注 async setAlias(userName, alias = '')

userName:UserName,NickName或RemarkName alias:备注

import ItChat4JS from 'itchat4js';

const itChat4JsIns = new ItChat4JS();

const doFn = async () => {
    await itChat4JsIns.login();
    const info = itChat4JsIns.getContactInfoByName('xxx');
    itChat4JsIns.setAlias(info.UserName, '备注名称');
};

doFn()

6.设置群组,好友置顶 async setPinned(userName, isPinned = true)

userName:UserName,NickName或RemarkName isPinned:是否置顶

import ItChat4JS from 'itchat4js';

const itChat4JsIns = new ItChat4JS();

const doFn = async () => {
    await itChat4JsIns.login();
    const info = itChat4JsIns.getContactInfoByName('xxx');
    itChat4JsIns.setPinned(info.UserName, true);
};

doFn()

7.创建群聊 async createChatRoom(memberList, topic = '')

memberList:用户列表({UserName: 'xxx}) topic:群名称

import ItChat4JS from 'itchat4js';

const itChat4JsIns = new ItChat4JS();

const doFn = async () => {
    await itChat4JsIns.login();
    const userArr = itChat4JsIns.getContactInfoByName(['AAA', 'BBB']);
    itChat4JsIns.createChatRoom(userArr, '群聊名称');
};

doFn()

8.设置群聊名称 async setChatRoomName(chatRoomUserName, name) {

chatRoomUserName:群UserName name:群名称

import ItChat4JS from 'itchat4js';

const itChat4JsIns = new ItChat4JS();

const doFn = async () => {
    await itChat4JsIns.login();
    const info = itChat4JsIns.getContactInfoByName('XXX');
    itChat4JsIns.setChatRoomName(info.UserName, '群聊名称');
};

doFn()

9.删除群成员 async deleteMemberFromChatRoom(chatRoomUserName, memberList) {

Tip:删除群成员总是返回Ret:1不成功(网页版也不成功)

chatRoomUserName:群UserName memberList:用户列表({UserName: 'xxx}

import ItChat4JS from 'itchat4js';

const itChat4JsIns = new ItChat4JS();

const doFn = async () => {
    await itChat4JsIns.login();
    const userArr = NodeWeChatIns.getContactInfoByName(['AAA', 'BBB']);
    const info = itChat4JsIns.getContactInfoByName('XXX');
    itChat4JsIns.deleteMemberFromChatRoom(info.UserName, userArr);
};

doFn()

10.添加群成员 async addMemberIntoChatRoom(chatRoomUserName, memberList, useInvitation = false) {

chatRoomUserName:群UserName memberList:用户列表({UserName: 'xxx}) useInvitation:是否以发出邀请的形式

import ItChat4JS from 'itchat4js';

const itChat4JsIns = new ItChat4JS();

const doFn = async () => {
    await itChat4JsIns.login();
   const userArr = NodeWeChatIns.getContactInfoByName(['AAA', 'BBB']);
    const info = itChat4JsIns.getContactInfoByName('XXX');
    itChat4JsIns.addMemberIntoChatRoom(info.UserName, userArr, true);
};

doFn()

静态方法

1.发送文件 async sendFile(fileDir, toUserName, mediaId, streamInfo = {})

};

doFn();

或者

import ItChat4JS, { sendVideo } from 'itchat4js';

import fs from 'fs';

const itChat4JsIns = new ItChat4JS();

const doFn = async () => {
    await itChat4JsIns.login();
    const stream = fs.createReadStream('./file/video.mp4');
    const streamInfo = {
        fileReadStream: stream,
        //filename: 'video.mp4',
        //extName: '.mp4'
    };
    sendVideo(null, 'filehelper', null, streamInfo)
};

doFn()

};

doFn();

4.撤回发送的消息 async revokeMsg(msgId, toUserName, localId)

    const {MsgID, LocalID} =  await sendTextMsg('Hello File Helper', 'filehelper');
    revokeMsg(res.MsgID, username, res.LocalID);
};

doFn();
