// 创建HttpRequest对象
HttpRequest httpRequest = new HttpRequest(HttpMethods.POST);
httpRequest.setUrl("http://example.com/api"); // 设置请求的URL

// 设置请求的参数
httpRequest.setContent("param1=value1&param2=value2");

// 设置请求的头部信息
httpRequest.setHeader("Content-Type", "application/x-www-form-urlencoded");

// 发送请求
