PicoHTTP is a tiny web server written in .NET - less than 100 lines of code! The purpose of this web server is to help with learning the HTTP protocol. You deal with raw HTTP requests and responses in this server allowing you to play around with the lower level HTTP details.
The server is not meant to be built and deployed anywhere. You simply run it in your IDE (Visual Studio, Rider or VS Code) or on the command line.
The code currently uses .NET 7 so ensure you have it installed - https://dotnet.microsoft.com/en-us/download/dotnet/7.0
If you don't use an IDE then you can run the below in your Terminal/Command Prompt/PowerShell.
dotnet run
The server will start at http://localhost:5000. If you open this URL in the browser, you will get a message like "Hello, world! The current time is 15:18:29 PM" (with the current time, of course).
The above "Hello, world..." response code is implemented in HelloWorldRequestProcessor class. There is another example
request processor called AddNumbersRequestProcessor. Go to Program.cs and replace HelloWorldRequestProcessor on the
below line with AddNumbersRequestProcessor.
Change this:
var requestProcessor = new HelloWorldRequestProcessor();
To this:
var requestProcessor = new AddNumbersRequestProcessor();
Now run the code and open http://localhost/add/10/20. You should get the response 30.
The request processors implement IRequestProcessor interface. You can write your own request processors and use them in Program.cs.
