Description

你好！目前我们项目使用zuul做为网关搭配sentinel进行限流，通过实现ZuulBlockFallbackProvider自定义了限流后的返回结果，其中code我们定义为10018，message则提示限流。这样限流后会返回{"code":10018,"message":"限流提示..."}但是http状态码居然是10018，请问被限流后http状态码该如何设置成200而不跟随BlockResponse类的code？

Research direction
The user wants to customize the HTTP status code in ZuulBlockFallbackProvider when Sentinel triggers rate limiting. Currently, the status code follows the code in BlockResponse, which the user set to 10018. To set it to 200, investigate the getBlockResponse method in ZuulBlockFallbackProvider. You might need to override the method or create a custom fallback that explicitly sets the HTTP status on the response object. Check the Sentinel source code for Zuul adapter (e.g., sentinel zuul adapter module) and look at the default implementation. Also consider using a different approach such as modifying the request context or using a servlet filter to override the status code. The issue has one comment that may provide guidance.
