Function Write

net/http/httpjson/io.go:39–47

Write sets the Content-Type header field to indicate JSON data, writes the header using status, then writes v to w. It logs any error encountered during the write.

(ctx context.Context, w http.ResponseWriter, status int, v interface{})

// then writes v to w.
// It logs any error encountered during the write.
func Write(ctx context.Context, w http.ResponseWriter, status int, v interface{}) {
	w.Header().Set("Content-Type", "application/json; charset=utf-8")
	w.WriteHeader(status)

	err := json.NewEncoder(w).Encode(Array(v))
	if err != nil {
		log.Error(ctx, err)
	}
}

// Array returns an empty JSON array if v is a nil slice,
// so that it renders as "[]" rather than "null".
