本文介绍了使用 Spring RestTemplate 发起 GET 和 POST 请求的具体方法。包括如何设置请求头信息、参数传递以及响应结果的处理等关键步骤。

RestTemplate client = new RestTemplate();
HttpHeaders headers = new HttpHeaders();
headers.add("siteId", siteId);
HttpEntity<String> requestEntity = new HttpEntity<>(null, headers);

JSONObject body = client.exchange(url, HttpMethod.GET, requestEntity, JSONObject.class).getBody();

第2种方式：

package org.springframework.http;

HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_FORM_URLENCODED);
headers.add("X-Requested-With", "XMLHttpRequest");

MultiValueMap<String, Object> params = new LinkedMultiValueMap<>();

params.add("productName", "缴纳");
params.add("orderPeriod", "60");

HttpEntity<MultiValueMap<String, Object>> requestEntity = new HttpEntity<>(params, headers);
String body = restTemplate.postForObject(url, requestEntity, String.class);
System.out.println(body);

JSONObject data = JSON.parseObject(body);
