Httpclient 发送 post 请求可以封装多格式的参数，这篇我们封装map格式的：

1、客户端代码如下：

public NmpResponse doPostMap(NmpRequest request) throws IOException {
            logger.info("------------开始POST请求-nmpHttpClient-----------");
            HttpClient httpClient = new HttpClient();
            httpClient.getHttpConnectionManager().getParams().setConnectionTimeout(15000);
            PostMethod postMethod = new PostMethod(NMP_ROOT_URL+request.getUrl());
            postMethod = setHeaderAuthInfo(postMethod);
            //添加请求参数
            Map<String,String> params = request.getParams();
           if(null != params && params.size()>0){
                for(Map.Entry<String,String> param : params.entrySet()) {
                    String key = param.getKey();
                    String paramValue = params.get(key);
                    postMethod.addParameter(key, paramValue);
                }
            }
            NmpResponse response = new NmpResponse();//自己封装的一个返回对象
            try {
                logger.info("------------开始执行POST请求，url:{}------------",NMP_ROOT_URL+request.getUrl());
                int statusCode = httpClient.executeMethod(postMethod);
                logger.info("------------POST请求结束，code={}------------",statusCode);
                if (statusCode == 200){
                    response.setRespBody(postMethod.getResponseBody());
                    response.setResponseStr(postMethod.getResponseBodyAsString());
                    response.setRespHeaders(postMethod.getRequestHeaders());
                } else{
                    logger.error("请求出错code={}：{}" ,statusCode ,postMethod.getStatusLine());
                }
            } catch (IOException e){
                logger.error("请求出错IOException：{}" ,e);
                throw e;
            } finally {
                postMethod.releaseConnection();
                logger.info("------------结束POST请求-nmpHttpClient-----------");
            }
            return response;
        }

2、服务端就可以用map 格式的数据接收参数了。
