RestTemplate GET 请求添加header头和 多个参数的写法

 1     public String takePersonAccessRecord() {
 2        String url = "";
 3         HttpHeaders headers = new HttpHeaders();
 4         headers.add("Authorization", TOKEN);

11                 builder.queryParam(e.getKey(), e.getValue());
12             }
13             String realUrl = builder.build().toString(); // 在此处拼接真实请求地址  "?pageNo=1&pageSize=5"
14             log.info("realUrl:{}", realUrl);
15             HttpEntity<JSONObject> httpEntity = new HttpEntity<>(null, headers); 
16             ResponseEntity<String> exchange = restTemplate.exchange(realUrl, HttpMethod.GET, httpEntity, String.class, map);
17             log.info("返回结果:{}", exchange.getBody());
