分步骤：
1. 创建Model
2. 创建View
3. 创建Controller
4. 修改配置config.php

1. 创建Model

在目录Home\Model创建文件UserModel.class.php

<?php
namespace Home\Model;
use Think\Model;
class UserModel extends Model {
    protected $trueTableName = 'wp_users'; 
}

2. 创建View

在目录Home\View\Test创建文件test.html

this is template!!
<br>
param:{$name}
<br> 
<?php echo($name);?>
<?php
    //echo phpinfo();
//echo phpversion();
?>

3. 创建Controller

在目录Home\Controller创建文件TestController.class.php

<?php
namespace Home\Controller;
use Think\Controller;

class TestController extends Controller {


    public function test() {
        //$this->show("this is testhaha",'utf-8');
        //$this->success('新增成功22', 'test2');

        $User = new \Home\Model\UserModel('users','wp_','DB_CONFIG');
        $list = $User->select();


        //$name = 'ThinkPHP';
        $this->assign('name',$list[0]['user_login']);
        //$this->display();
        $this->display('test');
    }
}

4. 修改配置

在目录Home\Conf修改文件config.php

<?php
return array(
    //'配置项'=>'配置值'
    'DB_CONFIG' => array(
         'db_type'  => 'mysql',
         'db_user'  => 'root',
         'db_pwd'   => '******',
         'db_host'  => '121.42.151.190',
         'db_port'  => '3306',
         'db_name'  => 'wordpress'
    ),
);

访问地址：http://localhost:8080/cms/index.php/Home/Test/test

浏览器显示如下：

    this is template!! 
    param:Rick
