upd out该节点将msg.payload发送到指定的UDP主机和端口。支持组播。 这一模块是Node-red的核心模块,如果要与硬件,设备通信,都要通过该模块来实现。由于本章节点过多,所以分多期来讲,这一期我们先来看看http in,http out,http request, `` http in 该节点可以用于创建一个web服务的http接口,支持的方法有以下几...
在Node-RED中,http request节点可以用于发送各种复杂格式的HTTP请求。以下是关于http request节点各种复杂格式请求的详细解释: 1. 基本配置 URL:设置请求的URL。 Method:设置HTTP请求方法,如GET、POST、PUT、PATCH或DELETE。 Headers:设置请求的HTTP头部信息。 Cookies:如果设置,则可用于发送带有请求的cookie。 Payload:...
Node-RED是一个基于Node.js开发的流程编排工具,可以通过简单的拖拽和连接方式实现硬件设备、API接口、云服务等之间的快速集成和交互。在云计算领域中,Node-RED可以用于获取TCP/IP连接,实现数据的接收和发送。 TCP/IP是一组用于互联网通信的协议,包括传输控制协议(TCP)和网际协议(IP)。通过使用Node-RED,我们可以轻松...
'use strict';consthttp=require('http');constserver=http.createServer((req,res)=>{console.log(Date.now(),'Server get incoming request');setTimeout(()=>{console.log(Date.now(),'Server send response');
Node-RED generates this JSON for the HTTP Request. { "id": "b0bc5df11987f5b1", "type": "http request", "z": "8f44c46fbe03a48d", "name": "JSON Request", "method": "GET", "ret": "obj", "paytoqs": "ignore", "url": "", "tls": "", "persist": false, "proxy":...
2.打开http://localhost:3001 如上图,点击“Test Game Server”按钮,提示“game server is ok.”,则此项目game-server可用^_^! 聊天服务器 上面大体了解了pomelo,要入门还是以一个聊天服务器为入门示例最好,其它逻辑相对简单,入门学习不会因其它游戏逻辑影响。
Getting nodes in the runtime The asynchronoushelper.load()method calls the supplied callback function once the Node-RED server and runtime is ready. We can then call thehelper.getNode(id)method to get a reference to nodes in the runtime. For more information on these methods see the API...
