项目中遇到一个请求方式要求：
1 、POST 请求
2 、Content-Type: text/xml; charset=utf-8
项目是Java代码 使用的httpclick发送的请求，接下来让我看下如何实现，本部分只提供核心请求代码，之前分享过httpclick发送请求工具类，有兴趣的小伙伴可以查看下之前文章(●'◡'●)
代码如下：
public static String doPost(String url, JSONObject params) {String result = "";CloseableHttpResponse response = null;try {//设置请求地址，创建 URIBuilderURIBuilder uriBuilder = new URIBuilder(url);if (!params.isEmpty()) {List<NameValuePair> nvp = new ArrayList<>();for (String key : params.keySet()) {nvp.add(new BasicNameValuePair(key, params.getString(key)));}uriBuilder.setParameters(nvp);}HttpPost httpPost = new HttpPost(uriBuilder.build());httpPost.setConfig(REQUEST_CONFIG);//返回json数据时不需要下面一行headerhttpPost.setHeader("Accept", "text/xml");//定义Content-TypehttpPost.setHeader("Content-Type", "application/x-www-form-urlencoded");//发起请求response = HTTP_CLIENT.execute(httpPost);if (response.getStatusLine().getStatusCode() == CODE) {HttpEntity entity = response.getEntity();result = EntityUtils.toString(entity, "utf-8");} else {log.error("\n请求接口错误，请检查接口是否可以正常访问！");}log.info("\n发起接口请求信息\n地址：{}\n参数：{}\n请求方式：{}\n请求结果：{}", url, params.toJSONString(), httpPost.getMethod(), result);} catch (URISyntaxException | IOException e) {log.error("\n请求接口错误，请检查接口是否可以正常访问！\n地址：{},\n参数：{}", url, params.toJSONString());throw new RuntimeException(e.getMessage());} finally {try {if (response != null) {response.close();log.info("关闭连接请求！");}} catch (IOException e) {log.error("关闭发送请求失败！{}", e.getMessage());}}return result;}
