CryptoJS前端加密后端php 解密 前端加密jm(word){ var key = CryptoJS.enc.Latin1.parse('B55BA55A12ABCDEF'); //为了避免补位，直接用16位的秘钥 var iv = CryptoJS.enc.Latin1.parse('ABCDEF123A55A412'); //16位初始向量 let srcs = CryptoJS.enc.Utf8.parse(word); let encrypted = CryptoJS.AES.encrypt(word, key, ); return encrypted.toString(); },后端解密function decuserId($str){ $key = "B55BA55A12ABCDEF"; $iv = "ABCDEF123A55A412"; $decrypted = openssl_decrypt(base64_decode($str), 'AES-128-CBC', $key, 1, $iv); return $decrypted; }

Thinkphp6.0 获取绝对路径 在tp6.0 改到了App 基础类里面获取助手函数获取：app()>getRootPath() //获取应用根目录app()>getNamespace() //获取应用类库命名空间app()>version() //获取框架版本app()>getBasePath() //获取应用基础目录app()>getAppPath() //获取当前应用目录app()>getThinkPath() //获取核心框架目录app()>getConfigPath() //获取应用配置目录app()>getConfigPath() //获取应用配置目录

thinkphp6 动态连接数据库 //use think\facade\Config; $config = Config::get('database'); $config['connections']['tmp'] = [ 'type' => 'mysql', 'hostname' => 'localhost', 'database' => 'test', 'username' => 'root', 'password' => 'root', 'hostport' => 3306, 'params' => [], 'charset' => 'utf8mb4' ]; Config::set($config, 'database'); Db::connect('tmp')->query('select * from t limit 1');
