我想通过Go上Google App Engine上的帖子通过http发送[] byte数据。如何为请求构造bodyType和body?
package app import ( "http" "appengine" "appengine/urlfetch" "bytes" "fmt" ) func init() { http.HandleFunc("/post", post) } func post(w http.ResponseWriter, r *http.Request) { c := appengine.NewContext(r) bs := []byte{1,2,3} buf := bytes.NewBuffer(bs) client := http.Client{Transport: &urlfetch.Transport{Context:c}} if _, err := client.Post("http://localhost:8080/", "application/octet-stream", buf); err != nil { fmt.Println(err) } }
