SocketIO 怎么用？

前提条件：

这个sockeio要在生产环境中，意思是启动并不是bench start 启动的。

查看如下的配置，看是否有redis_socketio 和 socketio_port

frappe@e8811978c502:~/frappe-bench/sites$ cat common_site_config.json 
{
 "background_workers": 1,
 "developer_mode": 1,
 "dns_multitenant": false,
 "file_watcher_port": 6787,
 "frappe_user": "frappe",
 "gunicorn_workers": 5,
 "http_timeout": 6000,
 "live_reload": true,
 "maintenance_mode": 0,
 "no-cors": 1,
 "pause_scheduler": 0,
 "rebase_on_pull": false,
 "redis_cache": "redis://localhost:13000",
 "redis_queue": "redis://localhost:11000",
 "redis_socketio": "redis://localhost:12000",
 "restart_supervisor_on_update": true,
 "restart_systemd_on_update": false,
 "serve_default_site": true,
 "shallow_clone": true,
 "socketio_port": 9000,
 "use_redis_auth": false,
 "webserver_port": 8000
}

查看进程是否有在运行。

frappe@e8811978c502:~/frappe-bench/sites/site1.local$ sudo supervisorctl status all

查看一下浏览器这里的console是否有报错。

最后通过如下的方法来确认socketio工作没有问题。

C:\Users\jianc>curl "http://192.168.32.2/socket.io/?EIO=4&transport=polling"
0{"sid":"e2xXQht7jqCwrRihAACP","upgrades":["websocket"],"pingInterval":25000,"pingTimeout":20000,"maxPayload":1000000}

用法：

后续的调试，客户端直接用浏览器的控制台就可以，服务端用服务器的bench console

bench console的进入方式：

frappe@e8811978c502:~/frappe-bench$ bench use site1.local
Current Site set to site1.local
frappe@e8811978c502:~/frappe-bench$ bench console
Apps in this namespace:
frappe, erpnext, erpnextcn, meeting

In [1]: frappe.publish_realtime("custom_event")

方法1：确认连接可工作

client:
frappe.realtime.on("custom_event",() => { console.log("Hello,call from back.")});

server:
frappe.publish_realtime("custom_event")

服务端发送完之后，可以在浏览器的控制台得到输出。
