rest - Golang services response file -


how can return file service more efficiently in go? example, receive file this

here example use receive file service:

func (b *benefitlisthandler) uploadappend(w http.responsewriter, r *http.request) {     r.parsemultipartform(32 << 20)     file, handler, err := r.formfile("benefitlistuploadfile")     if err != nil {         libhttp.encodeerrorresponse(w, err, http.statusinternalservererror)         return     } defer file.close() f, err := os.openfile("./"+handler.filename, os.o_wronly|os.o_create, 0666) if err != nil {     libhttp.encodeerrorresponse(w, err, http.statusinternalservererror)     return }  defer f.close() io.copy(f, file)  go b.readfileappend("./" + handler.filename)  libhttp.encodeokresponse(w, true)}

after that, confused how can send file request binary, improve time , consumption.

after information question solution

to specify browser file put header response:

w.header().set("content-disposition", "attachment; filename=nameoffile")

after read file ioutil:

files, err := ioutil.readfile(result)

and @ end use http.responsewriter write []byte of file response

w.write(files)
