OpenFeign调用包含Cookie的接口

    @Headers("Cookie: {cookie}")
    @PostMapping("/xxxx/login")
    Object login(@RequestHeader("Cookie") String cookie, @RequestBody LoginDTO dto);

这个cookie怎么获取呢？在RequestHeader中可以看到

在代码中获取

        ResponseEntity<byte[]> response = restTemplate.getForEntity(url, byte[].class);
        // 获取响应头
        HttpHeaders responseHeaders = response.getHeaders();
        // 获取响应头中的Cookie
        List<String> cookies = responseHeaders.get(HttpHeaders.SET_COOKIE);

        // 打印Cookie内容
        if (cookies == null) {
            log.error("获取Cookie失败");
            return ResponseEntity.status(500).body(null);
        } else {
            iconCookie = cookies.get(0);
            log.info(iconCookie);
        }
