在 Manus 中运行

Canvas

Use canvas to show HTML on connected Mac/iOS/Android nodes.

Model

Canvas host serves files from plugins.entries.canvas.config.host.root.
Canvas routes live on the Gateway HTTP port (gateway.port, default 18789).
Node bridge sends canvas URLs to connected node apps.
Node apps render URLs in a WebView.
Host name follows gateway.bind: loopback local only, LAN IP for LAN, Tailscale host for tailnet, auto picks best route.
Localhost URLs only work for a node on the same machine.
Paired nodes normally receive node-scoped pluginSurfaceUrls.canvas capability URLs; prefer those when available.

Config

Active config: $DEX_CONFIG_PATH or ~/.dex/openclaw.json.

{
  "plugins": {
    "entries": {
      "canvas": {
        "config": {
          "host": {
            "enabled": true,
            "root": "~/.dex/canvas",
            "liveReload": true
          }
        }
      }
    }
  },
  "gateway": { "bind": "auto" }
}

Actions

present: show canvas, optional URL.
hide: hide canvas.
navigate: open new URL.
eval: run JavaScript in current canvas.
snapshot: capture screenshot.

Workflow

Ensure Canvas plugin host is enabled.
Put HTML/CSS/JS under plugins.entries.canvas.config.host.root or the default state canvas dir.
Use a route reachable by the target node.
Present the hosted URL: /__openclaw__/canvas/<file>.html.
Use snapshot when the user needs proof.

URL shape

http://<gateway-host>:<gateway.port>/__openclaw__/canvas/index.html
http://<gateway-host>:<gateway.port>/__openclaw__/canvas/games/snake.html

Path mapping:

/__openclaw__/canvas/index.html -> <canvas host root>/index.html
/__openclaw__/canvas/games/snake.html -> <canvas host root>/games/snake.html

Troubleshooting

Node sees localhost but is remote: fix gateway.bind or public URL, regenerate URL.
LAN node cannot load: verify same network, firewall, Gateway port, and auth/capability URL.
Tailnet node cannot load: verify Tailscale status and advertised host.
Blank page: open URL locally, check browser console, then snapshot node.
Live reload missing: verify liveReload and file write under root.
