记录一个SQL自动执行的html页面

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：

HTML 页面代码

<style>body {font-family: Arial, sans-serif;margin: 0;padding: 20px;background-color: #f4f4f4;}h2 {color: #333;}button {background-color: #007BFF;color: white;border: none;padding: 10px 20px;cursor: pointer;border-radius: 5px;transition: background-color 0.3s ease;}button:hover {background-color: #0056b3;}#output, #failedSql, #slowSql, #completionMessage {margin-top: 20px;padding: 15px;background-color: white;border-radius: 5px;box-shadow: 0 2px 4px rgba(0,0,0,0.1);}#failedSql {background-color: #ffe6e6;border-left: 5px solid #d9534f;}#slowSql {background-color: #fff3cd;border-left: 5px solid #f0ad4e;}#completionMessage {background-color: #dff0d8;border-left: 5px solid #5cb85c;}.modal {display: none; /* 默认隐藏 */position: fixed;z-index: 1;left: 0;top: 0;width: 100%;height: 100%;overflow: auto;background-color: rgb(0,0,0);background-color: rgba(0,0,0,0.4);padding-top: 60px;}.modal-content {background-color: #fefefe;margin: 5% auto;padding: 20px;border: 1px solid #888;width: 80%;border-radius: 5px;}.close {color: #aaa;float: right;font-size: 28px;font-weight: bold;cursor: pointer;}.close:hover,.close:focus {color: black;text-decoration: none;}</style><h2>第53届名家具展邀约渠道统计</h2><h5>仅限公司内网操作（192.168.100.100-250）</h5><button onclick="fetchAndExecuteSqlStatements()">开始执行</button>

</script>

模板赋值(ThinkPHP5)

    private function getSql(){$name = 'miniform';$info = get_addon_info($name);$config = get_addon_config($name);$arr = isset($config['qudaosql']) ? $config['qudaosql'] : [];return $arr;}public function aa(){if($this->request->isGet()){$arr = self::getSql();$this->view->assign('sqlTasks',json_encode($arr));return $this->view->fetch();}}

执行SQL后端部分（PHP ）

    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]);} return json_encode(['code'=>1]);}

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：
