后端Api和数据库示例

[Db::input]可以读取post和get的参数

数据库的账号密码设置在文件夹[shiplang]->[db.php]

[Db::return_json_exit]是返回json，并且支持返回结果翻译，详细文档：https://shiplang.com/zh-cn/dosc/lang-api

[h5_php]里面是php后端文件夹，其中里面的Api方法命名必须是[api_]，才是api接口

[h5_php]和[h5_html]是相同目录对应关系

class NbHtml {
    public function api_test() {
        $id = Db::input('id','');//假设：1.com/a/api_test?id=1，那么input就是读取链接里的id
        if (empty($id)) {
            Db::return_json_exit(['code' => 400,'msg' => '请输入id']);
        }
        
        Db::execute("INSERT INTO aaa (id,bbb) VALUES (?,?)",['1','bbb']);//增
        Db::execute("DELETE FROM aaa WHERE id = ?", ['1']);//删
        Db::execute("UPDATE aaa SET bbb = ? WHERE id = ?",['new_bbb','id']);//改
        $user = Db::query("SELECT * FROM aaa WHERE id = ?", [$id]);//查 使用query
        
        Db::return_json_exit(['code' => 200,'msg' => '查询结果','data' => [
            'user' => $user
        ]]);
    }
}
