node-red

问题 I'm able to use the node-red-node-watson library to call an instance of Watson Conversation hosted in the US-South region of IBM Cloud. If I try it in the Germany region, it does not work. In github I spotted the following line ConversationV1.URL = 'https://gateway.watsonplatform.net/conversation/api'; which is the URL for Conversation in US-South. The URL shown in Bluemix VCAP_SERVICES for the Frankfurt instance is different: "https://gateway-fra.watsonplatform.net/conversation/api" I'm not

问题 first line in a Node red Function Node is var moment = require('moment-timezone'); ... I am trying to establish a timezone correct date/time stamp for sensor data.

问题 I am using the email node to connect to gmail. I receive "Error - Invalid Login" on the node. In the email node, I've set the following parameters: To: email-i-want-to-email-to@anymail.com Server: smtp.gmail.com Port: 465 (which I believe is an SSL port as per the link below) UserID: gmail-account (or should this be gmail-account@gmail.com - I've tried both) Password: the password on the "gmail-account" Name: email out This conforms to what I found at the following forum, but I am getting

问题 Is it possible to make an inject node that fires every 5 seconds, but not depending on deployment, instead in a fixed time grid. For example, an inject node with a 5 second interval would fire at hh:mm:08, hh:mm:13, hh:mm:18 etc. when deployed at hh:mm:03. Is there a way to delay it so that messages are sent exactly(*) at hh:mm:05, hh:mm:10, hh:mm:15 no matter in which second it was deployed? A possible solution would be to set the repeat interval to 1 second, and use a function node to only

问题 I am trying to send a byte array through POST using Node-RED. I can successfully create the buffer using this module and storing it in msg.payload .

So I use the payload in the following url: localhost:port/path?var=\"{{payload}}\" , but it gives "Error converting http params to args: invalid character '\' looking for beginning of value" If using it in the

问题 I got Problems with websockets on my Azure WebApp. I cloned Node-red from github and published it onto a brand new WebApp in Azure (using VisualStudioOnline).

But the websockets still do not work: Chrome does show the following Error: Error in connection establishment: net::ERR_CONNECTION_TIMED_OUT I can not

问题 I'm trying to create a new node for Node-Red. Basically it is a udp listening socket that shall be established via a config node and which shall pass all incoming messages to dedicated nodes for processing. This is the basic what I have: function udpServer(n) { RED.nodes.createNode(this, n); this.addr = n.host; this.port = n.port; var node = this; var socket = dgram.createSocket('udp4'); socket.on('listening', function () { var address = socket.address(); logInfo('UDP Server listening on ' +

I have try this a number of times and changed the server location from UK to USA. However it never works. 回答1: it is a known issue about a node.js module not building correctly.
