【养虾活动】openclaw 钉钉channel的报错400解决

问题
钉钉发消息收到 400 错误：Invalid `model`. Use `openclaw` or `openclaw/<agentId>`.

根因
钉钉插件把 model 参数硬编码为 `'main'`，但 Gateway HTTP 端点只接受 `'openclaw'`。

修改1. 添加钉钉渠道配置
File: `~/.openclaw/openclaw.json`

Added to `channels`:
```json
"dingtalk-connector": {
  "enabled": true,
  "clientId": "dingrl*******",
  "clientSecret": "WcU...",  // 你的 AppSecret
  "gatewayToken": "123****"
}
```

2. 启用 HTTP 端点  解决报错404
File: `~/.openclaw/openclaw.json`

Added to `gateway`:
```json
"http": {
  "endpoints": {
    "chatCompletions": { "enabled": true }
  }
}
```

3. 修复 model 参数 解决报错400
File: `~/.openclaw/extensions/dingtalk-connector/plugin.ts`

Line 1430:
```diff
- model: 'main',
+ model: 'openclaw',
```
