防止 SQL 注入

Question

问题 1：

我有下面的 MySQL 查询，它工作正常，但我刚刚发现这不是一种安全的方法，因为它对 SQL 注入开放。如您所见，如果我想作为参数传递， where 子句是一个问题。

_, err := dbmap.Select(&response.AppsData, "SELECT...", ?)

任何建议都非常有用。

where := ""

for i := 0; i < (len(acl_user_apps)); i++ {

    fmt.Println(acl_user_apps[i].AppId)

    fmt.Println(acl_user_apps[i].Permissions)

    if where == "" {

        where = "WHERE Apps.id=" + strconv.Itoa(acl_user_apps[i].AppId)

    } else {

        where = where + " OR Apps.id=" + strconv.Itoa(acl_user_apps[i].AppId)

    }

}

query := "SELECT Apps.*, GROUP_CONCAT(DISTINCT IFNULL(AppCategoryMatches.category_id,'-1') SEPARATOR ',') as temp,   GROUP_CONCAT(DISTINCT IFNULL(AppCategories.category_name,'-1') SEPARATOR ',') as tmp_name FROM Apps LEFT JOIN AppCategoryMatches ON AppCategoryMatches.app_id=Apps.id LEFT JOIN AppCategories ON (AppCategoryMatches.`category_id` = AppCategories.id) " + where + " GROUP BY Apps.id ORDER BY " + sort_by + " " + order_by + " LIMIT " + limit + " OFFSET " + offset)

_, err := dbmap.Select(&response.AppsData,query)

问题 2：也只是想知道是否有人在传递 ORDER 参数时遇到过问题......

_, err := dbmap.Select(&response.AppsData,

        "SELECT Apps.*, GROUP_CONCAT(DISTINCT IFNULL(AppCategoryMatches.category_id,'-1') SEPARATOR ',') as temp, GROUP_CONCAT(DISTINCT IFNULL(AppCategories.category_name,'-1') SEPARATOR ',') as tmp_name FROM Apps LEFT JOIN AppCategoryMatches ON AppCategoryMatches.app_id=Apps.id LEFT JOIN AppCategories ON (AppCategoryMatches.category_id = AppCategories.id) GROUP BY Apps.id ORDER BY ?", "title")

这个订单是有史以来最简单的事情......为什么它不起作用？
