Golang io / ioutil NopCloser

每当需要返回时

io.ReadCloser

Close()

NopCloser

您可以在此gorest分支中看到一个示例，在

util.go

//Marshals the data in interface i into a byte slice, using the Marhaller/Unmarshaller specified in mime.//The Marhaller/Unmarshaller must have been registered before using gorest.RegisterMarshallerfunc InterfaceToBytes(i interface{}, mime string) (io.ReadCloser, error) {    v := reflect.ValueOf(i)    if v.Kind() == reflect.Ptr {        v = v.Elem()    }    switch v.Kind() {    case reflect.Bool:        x := v.Bool()        if x { return ioutil.NopCloser(bytes.NewBuffer([]byte("true"))), nil        }
