DCNews
该工具能够即时捕捉微信群中的聊天消息，并将其自动同步到预设的Discord频道中
## 功能特性 * 文本/图片/接龙 消息实时同步至discord * 支持一同步多或者多同步一 * PIN 功能 (开发中) * DC斜杆命令配置同步项 ## 安装部署 > 实现过程：当收到一条新的群消息后，查询数据库对应表项，获取消息同步至哪个 DC 频道并发送消息，所以要配置 config.json 文件，包括 dc 机器人 key 和数据库连接方式，导入表结构，配置好表，程序即可开始同步 ### docker-compose 部署 1. 配置 docker-config.json 文件, 修改数据库密码，添加 Discord 机器人授权 token, 对应下面docker-compose.yaml文件 ```go { "Discord_bot_auth": "", "Static_path": "/app/static/", "Mysql_host":"192.168.210.11", "Mysql_port":"3306", "Mysql_db":"dcnews", "Mysql_user":"root", "Mysql_password":"root", "Dc_createsync_prompts": "正在建立微信与Dc同步渠道...\nStep 1.请添加微信: \nStep 2.将该微信拉入目标微信群，等待30秒\nStep 3.在目标微信群输入同步码: " } ``` 2. 在 docker-compose.yaml 中修改数据库映射端口和密码 ```go mysql: image: mysql:5.7 networks: dcnews_network: ipv4_address: 192.168.210.11 ports: - "23306:3306" environment: MYSQL_ROOT_PASSWORD: root MYSQL_DATABASE: dcnews ``` 3. 启动docker compose ``` docker compose up ``` 4. 在日志中找到微信登录链接 5. 手动连接数据库，关联群组对应频道，即可开始同步 ```go create_time 添加时间 dc_user dc用户名称 wx_user 微信用户名称 wx_group 微信群组名称 必填 dc_channel_id dc频道ID 必填 dc_channel_info dc频道介绍 必填，需为URL remark 备注 ``` ### 手动编译部署
1. 下载依赖包：
```shell
go mod download
```
2. 配置文件
```go
// 打开 config.json 配置 Discord 机器人key，静态文件存放路径，数据库连接方式
{
"Discord_bot_auth": "",
"Static_path": "",
"Mysql_host":"",
"Mysql_port":"",
"Mysql_db":"",
"Mysql_user":"",
"Mysql_password":"",
"Dc_createsync_prompts": "正在建立微信与Dc同步渠道...\nStep 1.请添加微信 \nStep 2.将该微信拉入目标微信群，等待30秒\nStep 3.在目标微信群输入同步码: "
}
```
3. 导入表结构
```
mysql -u -p
source dc_wx_association_table.sql
```
4. 构建项目：
```shell
go build
```
5. 运行项目:
```
chmod 744 ./dcnews
./dcnews
```
6. 项目日志：
```shell
logfile.log
```
7. 通过数据库关联群组对应频道
```
create_time 添加时间
dc_user dc用户名称
wx_user 微信用户名称
wx_group 微信群组名称 必填
dc_channel_id dc频道ID 必填
dc_channel_info dc频道介绍 必填，需为URL
remark 备注
```
## 使用DC斜杆命令创建同步
1. 在Dc中输入 /createsync 获取同步码
2. 在需要同步的微信群发送同步码，即可建立同步
