一、绪论

   JAVA接口返回信息ServerHttpResponse response

等登录接口token过期时需要给前端返回相关状态码和状态信息

二、Mono<Void>向前端返回没有登陆或登录超时 暂无权限访问信息组装

返回Mono对象

public abstract class Mono<T> implements CorePublisher<T>

<code>/**

* 无权限

*

* @param response

* @return

*/

private Mono<Void> noLogin(ServerHttpResponse response) {

log.info("没有登陆或登录超时 暂无权限访问===========");

String responseDataStr = JSON

.toJSON(ResponseData.error(HttpStatus.UNAUTHORIZED.value(), "The Token has expired")).toString();

byte[] bytes = responseDataStr.getBytes(StandardCharsets.UTF_8);

DataBuffer buffer = response.bufferFactory().wrap(bytes);

response.setStatusCode(HttpStatus.UNAUTHORIZED);

return response.writeWith(Mono.just(buffer));

}

信息组装。

1、返回ResponseData对象，输出状态码和状态信息：The Token has expired

ResponseData.error(HttpStatus.UNAUTHORIZED.value(), "The Token has expired")

转换成json信息

byte[] bytes = responseDataStr.getBytes(StandardCharsets.UTF_8);

转换成字节流

输出：

response.writeWith(Mono.just(buffer));

公共返回体封装：ResponseData
