Building RESTful Web services with Go

Running the code

We can run the program directly using the run command:

go run customMux.go

 Now, let us fire two CURL commands and see the output:

curl -X GET http://localhost:8000/randomFloatcurl -X GET http://localhost:8000/randomInt

The responses will be:

0.604660287979619687

Your response may change due to the random number generator.

We saw how we can create a URL router with basic Go constructs. Now we are going to look at a few popular URL routing frameworks that are widely used by the Go community for their API servers.
