golang: Getting string from []byte

I'm new to go (coming from the C++ world)

I've created a new writer, which "inherits" from io.writer:

type httpWriter struct {
  io.Writer
}

Next I've implemented the Write() function of the io.Writer interface:

func (w *httpWriter) Write(p []byte) (n int, err, error){...}

Then, I've redirected all output to that writer.

I'm having truble to print the actual string in the Write() implementation. I've tried all string formatting I could find in the documentation, but none of them give me the original string as an output.

fmt.Printf("%s\n",p) \\etc..

Would appreciate assistance

Ok, two things:

  1. You haven't "inherited" io.Writer (you simply stated that your struct contains a writer). In go, interfaces are implicit. If your struct implements Write(p []byte) (n int, err, error), it is an io.Writer and can be used with any function accepting it. Period. No need to declare anything.

  2. As for your problem: fmt.Printf("%s\n", string(p))
