restTemplate的使用（证书正常，不用跳证书）

　　　　　//设置请求头
        HttpHeaders header = new HttpHeaders();
        header.setContentType(MediaType.APPLICATION_FORM_URLENCODED);
        //  封装参数，千万不要替换为Map与HashMap，否则参数无法传递

        //获取token
        MultiValueMap<String, String> param = new LinkedMultiValueMap<>();
        //添加请求的参数
        param.add("key", "value");
        HttpEntity<MultiValueMap<String, String>> requestEntity = new HttpEntity<>(param, header);
        //  执行HTTP请求

        ResponseEntity<String> response = restTemplate.exchange(url, HttpMethod.POST, requestEntity, String.class);

        if (response.getStatusCodeValue() == 200){
            String body = response.getBody();
            if(body != null){
                JSONObject jsonObject = JSON.parseObject(body);
                Object access_token = jsonObject.get("access_token");
                token = (String) access_token;
            }
        }else {
            log.warn("请求异常");
        }
