RestTempLate 请求头、参数、请求体设置

参考:https://blog.csdn.net/qq_35642849/article/details/103821900

应用场景:通过微信公众号access_token接口获取到token,然后查询公众号的文章列表。

//region 2.获取文章列表
 String articleUrl = "https://api.weixin.qq.com/cgi-bin/material/batchget_material";
 //设置请求头
 HttpHeaders httpHeaders = new HttpHeaders();
 httpHeaders.add("Content-Type", MediaType.APPLICATION_JSON_UTF8_VALUE);
 //设置参数
 MultiValueMap<String, String> queryParams = new LinkedMultiValueMap<>();
 queryParams.add("access_token", accessToken);
 UriComponentsBuilder builder = UriComponentsBuilder.fromHttpUrl(articleUrl).queryParams(queryParams);
 //设置请求体
 Map<String, String> params = new HashMap<>();
 params.put("type", "news");
 params.put("offset", "0");
 params.put("count", "1");
 String jsonData = JSON.toJSONString(params);
 HttpEntity<String> request = new HttpEntity<>(jsonData, httpHeaders);
 
 String queryResult = restTemplate.postForObject(builder.toUriString(), request, String.class);
 //endregion
