Symfony FOSRestController Empty Response

我有put方法，我希望在逻辑之后有一些响应"Projects successful update"，当数字错误和描述时我使用statusCode，但当我的操作完成时，我有204 No Content。但是当

return "update old project"; 

但这是错误的，我想使用状态代码和描述，为什么我没有响应不理解

Response Body [Raw]
"update old project"

我用sanbox测试它，因为如果我测试PUT方法，poster不会在请求中发送参数，而POST会将参数发送到操作。
