记录一个SQL自动执行的html页面

hj10432025-03-14 11:23

在实际工作场景中，需要运用到大量SQL语句更新业务逻辑，对程序员本身，写好的sql语句执行没有多大问题（图1），但是对于普通用户来说还是有操作难度的。因此我们需要构建一个HTML页面（图2），并结合JavaScript来发送请求到服务器端执行SQL语句。这里需要注意的是，在实际应用中直接通过前端请求执行SQL语句存在严重的安全隐患（如SQL注入攻击），通常的做法是在服务端进行严格的验证和处理。

以下是我的一个实际案例：

模板赋值(ThinkPHP5)

php 复制代码 
    // 获取SQL执行语句的方法
    private function getSql(){
        $name = 'miniform';
        $config = get_addon_config($name);
        $arr = isset($config['qudaosql']) ? $config['qudaosql'] : [];
        return $arr;
    }

    // 渠道更新页面访问方法
    public function aa(){
        if($this->request->isGet()){    // GET请求
            $arr = self::getSql();    // 获取SQL执行语句
            // dump($arr);
            $this->view->assign('sqlTasks',json_encode($arr));    // 模板赋值，输出json字符串
            return $this->view->fetch();
        }
    }

执行SQL后端部分（PHP ）

php 复制代码 
    public function execSql($sql){
        // sql语句校验
        $arr = self::getSql();
        $arr = array_values($arr);
        if(!in_array($sql,$arr)){
            return json_encode(['code'=>0,'msg'=>'非法sql']);
        }
        $exec = Db::execute($sql);
        if($exec===false){
            return json_encode(['code'=>0,'msg'=>'执行失败']);
        } 
        return json_encode(['code'=>1,'msg'=>'执行成功']);
    }

执行结果：

安全设置：

1、防火墙设置IP白名单，如我这里只允许公司内网部分IP可用；

2、后端检查SQL语句是否自己预设的语句，否则提示"非法语句"；

补充一段上述代码中涉及到的SQL语句，供参考：

在fa后台，用fieldset组件简单做一个SQL配置，虽然不太好看但能用就行，如下图所示：
