2.一个跨语言的http接口方法

<span style="font-family:KaiTi_GB2312;font-size:18px;">  /**
     * 訪问php接口
     *
     * @param url
     * @return
     */
    private static String sendRequest(String url) {
        InputStream inputStream = null;
        GetMethod getMethod = null;
        try {
            //url = chineseToUtf8(url);
            getMethod = new GetMethod(url);
            int statusCode = 0;
            statusCode = httpClient.executeMethod(getMethod);
            if (statusCode != HttpStatus.SC_OK) {
                logger.debug("訪问目标url:{0} 失败,http状态码：{1}", new Object[] { url, statusCode });
                return StringUtils.EMPTY;
            }
            inputStream = getMethod.getResponseBodyAsStream();
            if (inputStream == null) {
                logger.debug("訪问目标url:{0} 失败,返回io流为空", new Object[] { url });
                return StringUtils.EMPTY;
            }
            return IOUtils.toString(inputStream, "UTF-8");
        } catch (HttpException e) {
            logger.error(HuDongErrorCodeEnum.RemoteRequestError, "网络原因,訪问目标url:" + url + "失败", e);
            return StringUtils.EMPTY;
        } catch (IOException e) {
            logger.error(HuDongErrorCodeEnum.RemoteRequestError, "io原因,訪问目标url:" + url + "失败", e);
            return StringUtils.EMPTY;
        } catch (Exception e) {
            logger.error(HuDongErrorCodeEnum.RemoteRequestError, "訪问目标url:" + url + "失败", e);
            return StringUtils.EMPTY;
        } finally {
            if (getMethod != null) {
                getMethod.releaseConnection();
            }
            if (inputStream != null) {
                try {
                    inputStream.close();
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
        }
    }</span>

5.扩展说明，兼容IE处理

使用jsonObject传送数据的时候，会存在ie7、8不兼容的问题。不支持json的stringify 方法。网上有一些兼容处理，认为不错的有：IE下JSON 没有定义

方法1、设置兼容模式：

IE8和IE9中都能正常执行（大概是IE8和IE9都提供了原生的JSON解析和序列化）

<meta http-equiv="X-UA-Compatible" content="IE=edge" />

方法2、引用json2.js文件到页面

http://www.json.org/

搜索 json2.js,下载压缩包

把json2.js引入到页面，就OK了。

官网地址：https://github.com/douglascrockford/JSON-js/

<script type="text/javascript" src="/Scripts/json2.js"></script>

方法3、推断当前浏览器是否支持JSON对象。假设不支持。则引入json2.js文件---没试成功

if(typeof JSON == 'undefined'){

                $("head").append($("<script type='text/javascript' src='../Js/json2.js'></script>"));

            }



官网地址一般都非常难找到下载的入口，目測了下好像仅仅有把下copy的可能。这里提供一个下载地址：
