http请求工具类

http请求工具类：

public static JSONObject httpPost(String url,String json, boolean noNeedResponse){  
        DefaultHttpClient httpClient = new DefaultHttpClient();  
        JSONObject jsonResult = null;  
        HttpPost method = new HttpPost(url);  
        try {  
            if (null != json) {  
                StringEntity entity = new StringEntity(json, "utf-8");  
                entity.setContentEncoding("UTF-8");  
                entity.setContentType("application/json");  
                method.setEntity(entity);  
            }  
            HttpResponse result = httpClient.execute(method);  
            url = URLDecoder.decode(url, "UTF-8");  
            if (result.getStatusLine().getStatusCode() == 200) {  
                String str = "";  
                try {  
                    str = EntityUtils.toString(result.getEntity());  
                    if (noNeedResponse) {  
                        return null;  
                    }  
                    jsonResult = JSONObject.fromObject(str);  
                } catch (Exception e) {  
                    logger.error(url, e);  
                }  
            }  
        } catch (IOException e) {  
            logger.error(url, e);  
        }  
        return jsonResult;  
    }
