Httpclient 发送 post 请求封装map 格式参数

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;
    }
