// example for unmarshalling an http request to JSON
contents, err := ioutil.Readall(req.Body)
if err != nil { return err }
req.Body.Close()
user := new(User)
if err := json.Unmarshal(contents, user); err != nil { return nil }
// do whatever you want with 'user'
Does Go have something analogous to Rust's `try!` or `?` operator, which would turn it into (pseudocode):
contents, err := try!(ioutil.Readall(req.Body)) contents, err := ioutil.Readall(req.Body)?(I don't know Go)
