Hallo,
ich möchte gerne automatisiert Daten von Node-Red in das Eingabefeld einer Webanwendung schreiben und diese Eingabe bestätigen. Hintergrund ist hier die Automatisierung einer Absauganlage die anhand von OPC-UA Daten automatisiert werden soll. Je nachdem welchen Wert die Daten liefern, soll dann der jeweilige soll-Unterdruckwert in die Websteuerung der Anlage geschrieben werden. Hat hiermit schonmal jemand Erfahrungen gemacht ? Eventuell gibt es eine Node die das automatisierte Schreiben über Node-Red in Webanwendungen ermöglicht ?
Vielen Dank schon vorab an alle die sich mit meiner Frage beschäftigen.
Well...
it's probably not a good idea to deliver a question to an international community, if that question is in German.
just for non-German speakers: it has been asked for a method to write s.th. into an input field of a web application by means of Node-RED
I do not know if Node-RED may be used to automate web pages or apps (e.g., by means of Selenium or similar).
However, if that web app is basically the front-end of a server application (which runs in the background) the browser console may be used to intercept the actual request to that server and mimic that by a Node-RED flow.
With greetings from Germany...
By the way,
there seem to be multiple Selenium web drivers for Node-RED, e.g. "nbr-web-app" which claims "NodeBot allows you to automate web applications like form filling, data extracting, testing"
Or " node-red-contrib-nbrowser" which "Provides a high level browser automation node based on nightmarejs.org"
Just visit the Node-RED library and search for "selenium"
Hi, sorry, you're right. I hadn't thought that an international community is active here when writing this article.
