The project is an example of an application that uses reverse proxy from the standartd library.
Let's assume you want to migrate your api from language X to golang.
Sometimes it's hard to rewrite everything at once and you want to move some handlers to golang, but use old application as a fallback.
I just want to show you that you don't have to use any 3rd-party proxies (like nginx) or write your own proxy logic.
The solution is quite simple and straightforward. We use reverse proxy and http server from the standard library.
- Clone or
go get -u github.com/beono/simproxythis project. - Run
go test && go run main.goto see it in action.
Send a request to http://localhost/hello and you will get a tiny text response.
Send a request to http://localhost:8080/oauth2/v3/certs and you will get a json response. This request was proxied to https://www.googleapis.com/oauth2/v3/certs, because this handler doesn't exist in our new application.
