七牛图片上传

准备工作：

1）http://developer.qiniu.com/article/kodo/kodo-first/quickstart.html    跟着文档创建七牛帐号，进入个人中心申请认证（需要3天审核，一般1天就可以了）和创建存储空间（上传的图片都会在这个空间的内容管理显示）

2）http://developer.qiniu.com/code/v7/sdk/php.html   根据里面的过程跟着执行，用composer安装

 

 3）安装好以后，用如下代码上传图片：

控制器： 

use app\models\Ceshi;
use yii;
//导入七牛相关类
use Qiniu\Auth;
use Qiniu\Storage\BucketManager;
use Qiniu\Storage\UploadManager;

class TestController extends Controller {
    public function actionIndex() {
        $model = new Ceshi();
        $data = $model->find()->orderBy(\'id desc\')->asArray()->all();
        if (Yii::$app->request->isPost) {
            $post = Yii::$app->request->post();
            //p($post);
            $image = $this->upload();
            if (!$image) {
                $model->addError(\'cover\', \'封面不能为空\');
            } else {
                $post[\'Ceshi\'][\'image\'] = $image;
            }

                if($model->save()){
                    p(\'添加成功\');
                }

                Yii::$app->session->setFlash(\'info\', \'添加失败\');
            }

        }
        //debug ( \'aaa\' );
        return $this->render ( \'index\',[\'model\'=>$model,\'data\'=>$data]);
    }

    private function upload()
    {

        list($ret,$err)=$uploadManager->putFile($token,$key,$filePath,null,$type,false);
        if($err){//上传失败
            returnJson("0001",[],"false",$err);
        }else{//成功
            //添加信息到数据库
            return $ret[\'key\'];
        }
    }

    /**

     * @return string
     */
    private function getToken(){
        $accessKey = Yii::$app->params[\'qiniu\'][\'ak\'];
        $secretKey = Yii::$app->params[\'qiniu\'][\'sk\'];
        $auth=new Auth($accessKey, $secretKey);
        $bucket = Yii::$app->params[\'qiniu\'][\'bucket\'];//上传空间名称
        //设置put policy的其他参数
        //$opts=[\'callbackUrl\'=>\'http://www.callback.com/\',\'callbackBody\'=>\'name=$(fname)&hash=$(etag)\',\'returnUrl\'=>"http://www.baidu.com"];
        return $auth->uploadToken($bucket);//生成token
    }
