问题描述
在 symfony5 控制器中,我可以通过以下方式返回 json 响应:
return $this->json(['key' => 'content');
然而,当我抛出 HttpException 时,我在开发和生产中都看到了默认的 html 错误页面.
我想创建一个restful api,所以我想把所有的HttpExceptions转换成json.
我想配置我所有的控制器以将它们的响应格式化为 json.最多,我想添加一个异常处理程序,将异常转换为正确的消息.(在 prod 中它应该有更少的信息,在 dev 中它可能包含异常堆栈跟踪.)
我怎样才能做到这一点?我以为我可以使用 @Route
注释的 format
选项,但它不起作用.
这是我的示例控制器:
json($ok);}}
在寻找这个时,我遇到了:
composer 需要 symfony/serializer-pack
之后,我的异常呈现为 json 很好.
Within a symfony5 controller, I can return json responses via:
return $this->json(['key' => 'content');
Yet when I throw an HttpException, I see the default html error page in both dev and production.
I want to create a restful api, so I want to convert all HttpExceptions into json.
I want to configure all my controllers to format their response as json. At most, I want to add one Exception handler that would transform the excpetions into proper messages. (In prod it should have less information, in dev it may contain the exception stacktrace.)
How can I achieve this? I thought I could use the format
option of the @Route
annotation but it doesn't work.
This is my example controller:
<?
While looking for this I came across
this PR which seems to achieve what I am trying to do, yet I am unsure what I am missing.
On the symfony blog I found following answer by Yonel Ceruto saying
yet I have no idea what this entails.
In dev and prod I got these html views instead of a json response:
prod
dev
解决方案
Turns out all I was missing was installing the serializer-pack as pointed out in the symfony docs:
composer require symfony/serializer-pack
Afterwards, my exceptions render as json fine.
