ESPeriments with Nginx (Part III)
Ave! This is the concluding part of the ESPeriments with Nginx series, where we’ll talk about testing out the HTTPS bits and wiring things up on the ESP8266 end to use HTTPS also. First off, we’ll need to test out the HTTPS API endpoint. Before doing this, I’ll assume the server (web) app is running and the Nginx proxy has been suitably configured (and includes the HTTPS directives as discussed in the previous post). Essentially, we’ll need to simulate HTTP and HTTPS requests to the API endpoint and see the response behavior and codes. There are an eclectic mix of tools to do this sort of work (e.g Postman, etc), but we’ll be using Fiddler by Telerik, which (IMHO) is a solid piece of kit. We’ll use Fiddler’s Composer tab to create a suitable request to the API endpoint. Essentially, the server (web) app is designed to receive a POST request whose payload is the JSON representation of a request object – which should contain a field called “Tag” for purposes of illustration. Here’s a
