java调用第三方接口，获取接口返回的数据。

Question

java接收远程调用的数据，得到的是如上个数的返回内容，我怎么写才能获取到值，现在使用的请求方法如下：

public static HttpResult postJsonData(String url, Map<String,String> params, String charset) throws Exception{  
    CloseableHttpClient httpclient = HttpClientUtil.createDefault();  
    HttpPost httpPost = new HttpPost(url);  
    //拼接参数  
  List<NameValuePair> list = new ArrayList<NameValuePair>();  
    for (Map.Entry<String, String> entry : params.entrySet()) {  
        String key = entry.getKey().toString();  
        String value = entry.getValue().toString();  
        System.out.println("key=" \+ key + " value=" \+ value);  
        NameValuePair pair = new BasicNameValuePair(key, value);  
        list.add(pair);  
    }  
    CloseableHttpResponse response=null;  
    try {  
        if(StringUtils.isEmpty(charset)){  
            charset = DEFAULT\_CHARSET;  
        }  
        httpPost.setEntity(new UrlEncodedFormEntity(list,charset));  
        response = httpclient.execute(httpPost);  
        /\*\*请求发送成功，并得到响应\*\*/  
  if(response!=null && response.getStatusLine().getStatusCode() == HttpStatus.SC\_OK){  
            HttpEntity httpEntity = response.getEntity();  
            if (httpEntity!=null){  
                System.out.println("响应内容为:" \+ EntityUtils.toString(httpEntity));  
                //System.out.println("响应内容为1:" + httpEntity.getContent());  
  }  
           String result=null;  
            try {  
                result = EntityUtils.toString(httpEntity,DEFAULT\_CHARSET);  
                logger.info(result);  
            } catch (IOException e) {  
                throw e;  
            } finally {  
               EntityUtils.consume(httpEntity);  
            }  
            return JSON.parseObject(result,HttpResult.class);  
           //return httpEntity.getContent();  
  }else{  
            return null;  
        }  
    } catch (IOException e) {  
       throw new Exception(e.getMessage());  
    }finally {  
        try{  
            // 释放资源  
  if(response!=null){  
                response.close();  
            }  
            if(httpclient!=null){  
                httpclient.close();  
            }  
        }catch (IOException e1){  
            throw new Exception("CloseableHttpResponse close exception");  
        }  
  
    }  
}

求教怎么写才能把返回的值取到，现在用上边的方法会报如下错误：

Answer 1

httpEntity 只能读取一次的，当调用这个指挥 EntityUtils.toString(httpEntity)，就被关闭了。这个只用一次，你看下还报错不

Answer 2

您好 您这问题解决了吗？可不可以分享一下？？
