Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

OpenClaw 的微信渠道插件,支持通过扫码完成登录授权。

兼容性

| 插件版本 | OpenClaw 版本 | npm dist-tag | 状态 | |---------|--------------------------|--------------|--------| | 2.0.x | >=2026.3.22 | latest | 活跃 | | 1.0.x | >=2026.1.0 <2026.3.22 | legacy | 维护中 |

插件在启动时会检查宿主版本,如果运行的 OpenClaw 版本超出支持范围,插件将拒绝加载。

前提条件

已安装 OpenClaw(需要 openclaw CLI 可用)。

查看版本:openclaw --version

一键安装

npx -y @tencent-weixin/openclaw-weixin-cli install

手动安装

如果一键安装不适用,可以按以下步骤手动操作:

1. 安装插件

openclaw plugins install "@tencent-weixin/openclaw-weixin"

2. 启用插件

openclaw config set plugins.entries.openclaw-weixin.enabled true

3. 扫码登录

openclaw channels login --channel openclaw-weixin

终端会显示一个二维码,用手机扫码并在手机上确认授权。确认后,登录凭证会自动保存到本地,无需额外操作。

4. 重启 gateway

openclaw gateway restart

添加更多微信账号

openclaw channels login --channel openclaw-weixin

每次扫码登录都会创建一个新的账号条目,支持多个微信号同时在线。

多账号上下文隔离

默认情况下,私聊可能共用同一会话桶。多个微信号同时登录时,建议按「账号 + 渠道 + 对端」隔离:

openclaw config set session.dmScope per-account-channel-peer

        "text_item": { "text": "你好" }
      }
    ]
  }
}

  2. 如需缩略图(图片/视频),同样计算缩略图的明文和密文参数
  3. 调用 getUploadUrl 获取 upload_param(和 thumb_upload_param
  4. 使用 AES-128-ECB 加密文件内容,PUT 上传到 CDN URL
  5. 缩略图同理加密并上传
  6. 使用返回的 encrypt_query_param 构造 CDNMedia 引用,放入 MessageItem 发送

卸载

openclaw plugins uninstall @tencent-weixin/openclaw-weixin

故障排查

"requires OpenClaw >=2026.3.22" 报错

你的 OpenClaw 版本太旧,不兼容当前插件版本。检查版本:

openclaw --version

安装旧版插件线:

openclaw plugins install @tencent-weixin/openclaw-weixin@legacy

Channel 显示 "OK" 但未连接

确保 ~/.openclaw/openclaw.jsonplugins.entries.openclaw-weixin.enabledtrue

openclaw config set plugins.entries.openclaw-weixin.enabled true
openclaw gateway restart
