namespace Home\Controller;
use Home\Controller\EmptyController;
class TestController extends EmptyController
{
    public function test()
    {
        if(empty($_POST[‘submit‘]))
        {
            $this->display();
        }
        else
        {
            $upload = new \Think\Upload();   //实例化文件上传类 第一个斜杠不能少
            $upload->maxSize = 3145728;
            $upload->exts = array(‘jpg‘,‘jpeg‘,‘png‘);
            $upload->savePath = ‘./‘;
            $CuoWuXinXi = $upload->upload();
            if(!$CuoWuXinXi)
            {
                $this->error($upload->getError());
            }
            else
            {
                $this->success(‘上传成功‘);
            }
        }
