同问

Spring boot 开始的时候直接返回字符串也是不通过，最后使用response.getWriter().print()返回成功 @GetMapping("/message/processing") public void msgProcessing(@PathParam("msg_signature") String msg_signature, @PathParam("timestamp") String timestamp, @PathParam("nonce") String nonce, @PathParam("echostr") String echostr, HttpServletResponse response) { log.info("----------微信接口访问日志----------"); log.info("msg_signature:{},timestamp:{},nonce:{},echostr:{}",msg_signature,timestamp,nonce,echostr); String msg = weComMessageService.wecomMessagePush(msg_signature,timestamp,nonce,echostr); log.info("明文:{}",msg); log.info("----------微信接口访问结束----------"); try { response.getWriter().print(msg); } catch (IOException e) { throw new RuntimeException(e); } }
