Question

我试图通过REST模板发送gzip压缩请求。

我的请求格式： -

url = apiUrl + mymethod + "?api_key=" + apiKey;
            RestTemplate restTemplate = new RestTemplate();
            HttpHeaders headers = new HttpHeaders();
            headers.add("api_key", apiKey);
            headers.add("Content-Type", "application/json");
            headers.setAccept(Arrays.asList(MediaType.APPLICATION_JSON));
            headers.add("Accept-Encoding", "x-gzip");

            HttpEntity<String> entity = new HttpEntity<String>("parameters",
                    headers);
            ResponseEntity<GenericResponseDto> response = null;

            try {
                response = restTemplate.exchange(url, HttpMethod.GET, entity,
                        GenericResponseDto.class);
            } catch (Exception e) {
                throw new CustomException(e, aPIAuditTrail);
            }
            log.info("Response :"+response);

发送此请求时会收到如下响应消息： - "Response(code=401, message=gzip not passed as header parameters)"

如果我将请求标题更改为

headers.add("Accept-Encoding", "gzip");

我得到例外： -

还尝试添加以下propeties application.prperties文件

server.compression.enabled=true
server.compression.mime-types=application/json,application/xml,application/javascript,text/html,text/xml,text/plain

没有改变同样的错误信息，如

"Response(code=401, message=gzip not passed as header parameters)"

我的Spring启动版本是1.3.5.RELEASE。

请帮我讲解如何在spring boot中发送压缩gzip请求？

如何在Spring启动时通过Rest Template请求解析GZIP压缩头？
