Hi All! I need a starting point for the following project I have in mind; I have seen a lot of sample code but nothing really helped me or was what I was looking for. My project is to have a MF RC522 module (using the lib) to create an access verification on a door. When the user presents his toke…

Does it have to be HTTP request? If your server can handle SSE you can use those to trigger certain actions. If validation is succesful, you could call a “open door” function. Webhooks might also be of interest, since those can make certains requests for you. What kind of server setup are you usin…

Thanks for the reply @Moors7 ! I have seen the “bouncer” project but this depends on the local DB from the core itself. in my project the core must check with a webserver+DB to verify the presented RFID token. Jep, I have a LAMP stack where also my domotica is running. So just standard HTTP POST bac…

the http client library is perfect for returning the data, it will give you a status code… which will be something like 200 or 400 maybe 500 (if your php code is anything like mine). but it will also give you the body in “response.body”. the library is available in the libraries in the webIDE, I mad…

Great work @Hootie81 ! But HttpClient could indeed be the best solution! i’m not afraid for SQL injections. My PHP code will deny this plus it will all be internal HTTP traffic. Do you maybe have a little peace of example code where I can work with? Where a please of JSON string is used in the resp…

i dont have an example with json, but with a few changes to the bitcoin example above you should be able to talk to your own server and get the json response. in BitcoinPrice.ino just change the lines at the top in the defines, the hostname and number of tokens your server will return. then there i…

Hey @Hootie81 , I’m using the “Bitcoin index” example that @BDub shared. This works much better than the HTTPClient lib. I’m now writing my PHP code on the server side which will handle the Webhooks and gives the core its feedback on what to do when a RFID token is presented. After that I will writ…

I have some code I use for webhooks written in php. Tomorrow morning I’ll fire up my laptop and share it. I ended up not using the webhooks and just did a http post to the server instead, cutting out the middle man so to speak. The code is the same either way you go… unless you use https which is …

I just made the decision to step-down from webhooks an go further on HTTP POST :smile: It will integrate better with my domotics which I already have running.

Its working! Using the “Bitcoin price index” as the example i have now successfully running an core which is able to verify the presented RFID token to an MySQL DB. Token is presented to the core Core does an HTTP POST request to my webserver with in the body an json sting containing token ID and …

awesome news! glad you got it going. Did it take many changes to get the client working? or the json section of code?

Have you thought about security? Maybe making use of the AES on the core already…
