composer安装七牛SDK
composer require qiniu/php-sdk
config文件保存七牛云配置信息
//七牛云空间配置
'qiniu' => [
'AccessKey' => 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx',
'SecretKey' => 'yyyyyyyyyyyyyyyyyyyyyyyyyyyyyyy',
'bucket' => 'zzzzz',
'domain' => 'demo.domain.net/'

测试上传功能
Controller：
public function test()
{
if ($this->request->isPost()) {
$qiniu = new \app\admin\model\Qiniu();
$data = $qiniu->upload('imgFile');
var_dump($data);
}
return $this->view->fetch();
}
