**直接上代码**

public static String post(String url, String head, String body) throws Exception { 
    
            // 创建httpClient的默认实例
            CloseableHttpClient httpClient = HttpClients.createDefault();
    
            // 忽略https证书验证
            httpClient = (CloseableHttpClient) wrapClient(httpClient);
    
            try { 
    
                // 创建POST请求
                HttpPost post = new HttpPost(url);
    
                // 设置请求头
                post.addHeader("reqParameter", head);
                post.addHeader("Content-Type", "text/plain");
    
                // 设置请求体
                StringEntity entity = new StringEntity(body, "utf-8");
                post.setEntity(entity);
    
                // 执行POST请求
                CloseableHttpResponse response = httpClient.execute(post);
                if (response != null) { 
                    log.info("请求成功, 响应状态: {}", response.getStatusLine().getStatusCode());
                    HttpEntity httpEntity = response.getEntity();
                    // 如果返回的内容不为空
                    if (httpEntity != null) { 
                        return EntityUtils.toString(httpEntity, "UTF-8");
                    }
                }
    
            } catch (Exception e) { 
                log.error("请求异常: e = {}", e);
                e.printStackTrace();
            } finally { 
                httpClient.close();
            }
            return null;
