如何在Spring Gateway中获取响应体

import org.springframework.cloud.gateway.filter.GatewayFilterChain;
import org.springframework.cloud.gateway.filter.GlobalFilter;
importimport org.springframework.http.server.reactive.ServerHttpResponse;
import org.springframework.stereotype.Component;
import org.springframework.web.server.ServerWebExchange;
import reactor.core.publisher.Mono;

@Component
public class ResponseFilter implements GlobalFilter {

    @Override
    public Mono<Void> filter(ServerWebExchange exchange, GatewayFilterChain chain) {
        ServerHttpResponse response = exchange.getResponse();
        // 获取响应体
        String responseBody = "获取到的响应体：" + response.getBody();
        // 对响应体进行处理，例如打印日志
        System.out.println(responseBody);
        // 继续执行过滤器链
        return chain.filter(exchange);
    }
}
