本文介绍了一个封装好的HTTP客户端工具类，包括GET和POST请求的方法实现。该工具类使用Java编写，通过DefaultHttpClient进行网络请求，并能处理JSON格式的数据。

public class HttpClientUtil {

    private static final Logger logger = LoggerFactory.getLogger(HttpClientUtil.class);

    public static String METHOD_GET = "Get";

    public static String METHOD_POST = "Post";


    public static String get(String url) {
        HttpClient httpClient = new DefaultHttpClient();
        // get method
        HttpGet httpGet = new HttpGet(url);

        //response
        HttpResponse response = null;
        try {
            response = httpClient.execute(httpGet);
        } catch (Exception e) {
            e.printStackTrace();
        }

        //get response into String
        String temp = "";
        try {
            HttpEntity entity = response.getEntity();
            temp = EntityUtils.toString(entity, "UTF-8");
        } catch (Exception e) {
            e.printStackTrace();
        }

        return temp;
    }

    public static String post(String url, String json) {
        HttpClient httpClient = null;
        HttpPost httpPost = null;
        String result = null;
        try {
            httpClient = new DefaultHttpClient();
            httpPost = new HttpPost(url);

            StringEntity entity = new StringEntity(json, "utf-8");//解决中文乱码问题
            entity.setContentEncoding("UTF-8");
            entity.setContentType("application/json");
            httpPost.setEntity(entity);
            HttpResponse response = httpClient.execute(httpPost);
            if (response != null) {
                HttpEntity resEntity = response.getEntity();
                if (resEntity != null) {
                    result = EntityUtils.toString(resEntity);
                }
            }
        } catch (Exception ex) {
            ex.printStackTrace();
        }
        return result;
    }
