HttpClient请求地址并携带参数

废话不多，直接上代码！

    /**
     * 
     * @param httpUrl
     * @param reqInfo
     * @return
     */
    public static StringBuffer sendPost(String httpUrl, RequestInfoDTO reqInfo) {
        try {
            logger.info("请求地址 --->" + httpUrl);
            PostMethod postMethod = new PostMethod(httpUrl);
            HttpClient httpClient = new HttpClient(); 
            String requestJson = com.bocins.springcloud.util.JsonUtils.obj2Json(reqInfo);
            logger.info("请求参数转json --->" + requestJson);
            postMethod.setRequestEntity(new StringRequestEntity(requestJson, "text/xml", "GBK"));
            httpClient.executeMethod(postMethod);
            BufferedReader reader = null;
            reader = new BufferedReader(new InputStreamReader(postMethod.getResponseBodyAsStream(),"UTF-8"));
            String lines;
            StringBuffer sb = new StringBuffer("");
            while((lines = reader.readLine()) != null){
                lines = new String(lines.getBytes());
                sb.append(lines); 
            }
            logger.info("服务调用返回结果 --->" + sb);
            return sb;
        }catch(Exception e){
            logger.info("****************服务调用出错****************",e);
        }
        return null;
    }
