Build request with IP address

Question

I would like to know how to build a request with server's IP address (not URL).

Actually I start with a given URL and then with the help of lenses rebuild the request:

   connect = do
        request' <- parseRequest "http://localhost"
        let request = setRequestMethod "POST"
                    $ setRequestHost (S8.pack ("xx.xxx.xxx.xxx"))
                    $ ...

It works fine but it's inelegant, clumsy code.

No, what's wrong with just passing your IP address into `parseRequest` instead of `localhost`, like `"http://xx.xxx.xxx.xxx"`? The `http://` should make it a valid URL. — user11228628, May 29 '19 at 15:58
You're right parsing with "http:// xx.xxx.xxx.xx" do the job, I was sure that I checked this without success but now it's working (strange, I messed surely something else at the time..) — user3680029, May 30 '19 at 04:45

This is more or less what you're supposed to do when you create a Request from scratch, except there's a predefined defaultRequest equivalent to http://localhost. So, use:

request = setRequestMethod "POST"
        $ setRequestHost (S8.pack "xx.xxx.xxx.xxx")
        $ ... 
        $ defaultRequest

and I think you're doing it right.
