+2. Config
+- config of database: config/db.toml
+- config of http server: config/http.toml
+
+
+3. Run
+
+```Go
+var handlers = map[string]func(w http.ResponseWriter, r *http.Request){}
+handlers["/"] = func(w http.ResponseWriter, r *http.Request) {
+    //rand.Seed(time.Now().UnixNano())
+    //cellphone := "1878020" + strconv.Itoa(int(1000+rand.Int31n(9999-1000)))
+    //mydefault.CreateUser(cellphone)
+
+    users := mydefault.GetUsersByIds([]uint64{})
+
+    var (
+        rsp string
+        it  time.Time
+        mt  time.Time
+    )
+
+    for i, u := range users {
+        it = time.Unix(u.InsertTime, 0)
+        mt = time.Unix(u.ModifyTime, 0)
+        rsp += fmt.Sprintf("%d: %d, %s, %s, %s\n", i, u.Id, u.Cellphone, it.Format(time.RFC3339), mt.Format("2006-01-02 15:04:05"))
+    }
+
+    io.WriteString(w, rsp)
