What's the best way to go about receiving binary data via HTTP in go? In my case, I'd like to send a zip file to my application's REST API. Examples specific to goweb would be great, but net/http is fine too.

Just read it from the request body
Something like
package main import ("fmt";"net/http";"io/ioutil";"log") func h(w http.ResponseWriter, req *http.Request) { buf, err := ioutil.ReadAll(req.Body) if err!=nil {log.Fatal("request",err)} fmt.Println(buf) // do whatever you want with the binary file buf }
A more reasonable approach is to copy the file into some stream
defer req.Body.Close() f, err := os.TempFile("", "my_app_prefix") if err!=nil {log.Fatal("cannot open temp file", err)} defer f.Close() io.Copy(f, req.Body)
