HttpListener

🌶️🌶️ - HTTP Listener sample

Shows how to use the HTTP related APIs in System.Net. Shows how to implement a HTTP listener to reply to incoming HTTP requests.

Note: this is NOT an HTTP server, just a sample to illustrate how to use the HTTP Listener class.

When working with ESP32 edit the nfproj files and add BUIID_FOR_ESP32 to the DefineConstants, like this:

<DefineConstants>$(DefineConstants);BUIID_FOR_ESP32;</DefineConstants>

Important: You need to have a good understanding of certificates to be able to properly write code using SSL with a specific certificate. We do recommend you to get some knowledge about this before trying to adjust the sample without knowing which certificate to use.

Hardware requirements

An hardware device with networking capabilities running a nanoFramework image. This sample is coded to use the STM32F769IDiscovery target board, but can be easily changed to any other target that has networking capabilities.
