Copying Body from one http.Request to another

[Ken GoNoob]

I need to receive an http request, modify the XML body slightly, and resend the request to another server. I'm receiving the original request (inreq), am able to 

dump the body and verify the contents, and then create a new request, like this:

    newreq := http.NewRequest(inreq.Method, dest, inreq.Body)

    newreq.Close = true

    newreq.Body = inreq.Body

    resp, err1 := client.Do(newreq)

however I get an error: http: Request.ContentLength=596 with Body length 0

Is there a different way I should be copying the body to newreq? Related, I also want to modify the body, but it's type is called an "io.ReaderCloser". I'm not sure how I can convert this to a string, modify, and get it back to being a ReaderCloser.

Suggestions appreciated...

Once the body is read, it can't be read again. Use ioutil.ReadAll to pull the body into a []byte. 

    newreq := http.NewRequest(inreq.Method, dest, inreq.Body)

    newreq.Close = true

    newreq.Body = inreq.Body

    resp, err1 := client.Do(newreq)

Read the body as described above or use io.Copy to copy it into a bytes.Buffer then call String()

Suggestions appreciated...
