Difference between created response in Silverstripe

测试后，下面的代码会产生相同的结果。我的问题是，两者之间有什么区别吗？

 public function someaction1(SS_HTTPRequest $request) {
        $this->setResponse(new SS_HTTPResponse());
        $this->getResponse()->setStatusCode(400);
        $this->getResponse()->setBody('invalid');
        return $this->getResponse();
    }
    public function someaction2(SS_HTTPRequest $request) {
        $this->response = new SS_HTTPResponse();
        $this->response->setStatusCode(400);
        $this->response->setBody('invalid');
        return $this->response;
    }

要添加，请返回$this->response；或返回$this->getResponse（）；必要的还是隐含的？

没有区别，只需打开父类定义，看看getResponse（）的作用：

public function getResponse() {
    return $this->response;
}

当你想返回HTTP错误时，最好使用

$this->httpError(400, 'invalid request');

（无需返回，因为它抛出异常）
