spring boot 中使用RestTemplate请求接口，get设置header

    public static void main(String[] args) {
        String url = "http://127.0.0.1:90/index/index/test";
        HttpHeaders headers = new HttpHeaders();
        headers.add("accept-language", "zh-CN,zh;q=0.9");
        headers.add("accept", "application/json");
        headers.add("user-agent", "curl/7.58.0");
        headers.add("content-type", "application/json");
        headers.add("origin", "http://127.0.0.1:90");
        headers.add("referer", "http://127.0.0.1:90");
        headers.add("accept-encoding", "gzip, deflate, br");
        RestTemplate restTemplate = new RestTemplate();
        HttpEntity<String> entity = new HttpEntity<>(headers);
        ResponseEntity<String> response = restTemplate.exchange(url,HttpMethod.GET,entity,String.class);
        String resp = response.getBody();
        System.out.println(resp);
    }
