springcloud gateway 的自定义过滤器中家请求参数 requestParams 没生效,有遇到过的老哥吗

 URI uri = exchange.getRequest().getURI(); StringBuilder query = new StringBuilder(); String originalQuery = uri.getRawQuery(); if (StringUtils.hasText(originalQuery)) { query.append(originalQuery); if (originalQuery.charAt(originalQuery.length() - 1) != '&') { query.append('&'); } } params.forEach((key,value) ->{ query.append(key); query.append('='); query.append(value); query.append('&'); }); try { URI newUri = UriComponentsBuilder.fromUri(uri).replaceQuery(query.toString()).build(true).toUri(); ServerHttpRequest request = exchange.getRequest().mutate().uri(newUri).build(); return chain.filter(exchange.mutate().request(request).build()); } catch (RuntimeException var8) { throw new IllegalStateException("Invalid URI query: \"" + query.toString() + "\""); } 

以上这种写法,参考了自带的 AddRequestParameter 过滤器的写法
