How to insert user input into Postgres Db using Go
php小编百草为你介绍如何使用Go将用户输入插入到Postgres数据库。在现代应用程序开发中,数据库是必不可少的一部分。Postgres是一个强大的开源关系型数据库管理系统,而Go是一种简洁高效的编程语言。将用户输入安全地插入到数据库中是一项重要的任务,本文将分享一种简单且安全的方法来实现这个目标。通过以下步骤,你将学会如何使用Go编写代码,将用户输入插入到Postgres数据库中,保护数据库免受SQL注入等安全风险的威胁。让我们开始吧!
问题内容
我正在尝试将字符串插入 postgres 数据库。而且我找不到正确的语法。这是代码:
func insertdb() { fmt.println("write your text") var input string fmt.scanln(&input) insertstmt := `insert into "todos"("do_info") values(**i need this**)` _, e := db.exec(insertstmt) checkerror(e) }
我想将 input
变量插入到我的 postgresql 数据库中。我应该如何在sql查询中的值后面写它?
values($1)
错误提示需要参数。
解决方法
您的代码会抱怨,因为查询有一个占位符 $1
并且它没有传递给 exec
函数的匹配参数。
您必须将输入传递给 exec
函数,以便它可以替换占位符。即:
fmt.Println("Write your text") var input string fmt.Scanln(&input) insertstmt := `insert into todos (do_info) values($1)` _, err = DB.Exec(insertstmt, input)
