int转string

context.SetCookie("user_cookie", string(u.Id), 1000, "/", "localhost", false, true)

这里如果是将整数直接转为字符串显示,应该考虑使用 strconv.FormatInt((int64(u.Id))
string(u.Id) 将生成一个rune 值为 u.Id 值的字符串。

路径处理的问题

很不错的一个Go Gin WEB的入门系列,点赞点赞点赞!!!

在看到关于处理用户头像信息的相关内容是,一些处理路径的方式有不对或者错误的地方:
比如:

path = path + "avatar\\"

更正确的处理方式应该是使用filepath.Join:

path = filepath.Join(path, "avatar")
