Going forward I will refer to that value as Testing it Out Click вЂњEncodeвЂќ and copy the resulting value. So if your username is user1 and your password is password123 you would enter: user1:password123ДЈ. In the вЂњEncode to Base64 formatвЂќ textarea, enter: :

Some REST clients will handle this automatically, but in case yours doesnвЂ™t, here is how to get your base64 encoded username and password.Дў. In order to construct that header, we first need to Base 64 encode the username and password that we used to secure our ngrok tunnel. In order to send REST requests through our Ngrok Tunnel we will need to include an HTTP Basic authorization header.

Lines 46-64 : Using the value of the deviceВ request parameter, we determine which Arduino the request gets forwarded to.Д«ase64 Encode Your Ngrok Username and Password.

Line 36 : This is where we parse the actual value of that request parameter.

This indicates that device is a request parameter a variable portion of the request URL.

Line 30 : Define a POST route at the endpoint /complex-request/:device.

Based on the value of that request parameter the request is forwarded to one of two Arduinos or both Arduinos at once. This route receives a POST request containing JSON and a request parameter.

Line 26 : Reply to the original caller with an HTTP status code of 200 signaling that the request completed successfully.Line 24 : Send the request to the Arduino using the request-promise module and wait for that request to complete.The body of that request will be the JSON from the incoming request body. We will be sending a POST request to the arduinoUrl. Lines 17-22 : Define the request options for the outgoing request that will be sent to the Arduino.Line 15 : Copy the JSON data from the incoming request to a variable so we can use it in the outgoing request.Make sure to change the IP to match the IP of your Arduino on your local network. Lines 13-14 : Construct a URL based on the IP address of the Arduino.Line 11 : Define a POST route at the endpoint /forward-directly-to-arduino.

The next route receives a POST request and then forwards that request to an Arduino on our local network.

Lines 10-27: Forward Request Directly to Arduino You can see this route in action by typing your ngrok URL directly into your browser.

ItвЂ™s not strictly necessary for our purposes but it is useful to check if your app is running and that your tunnel is routing traffic correctly. All this route does is serve up the home page.
