使用java发送HTTP请求

public class Test {
    public static void main(String[] args) {
        BufferedReader in = null;
        String result = "";
        try {
            String path = "http://127.0.0.1:6666/webapp/servlet/workItemServlet?method=gotWorkItem&dataTime=05-01";
            URL realUrl = new URL(path);
            URLConnection connection = realUrl.openConnection();
            connection.setRequestProperty("accept", "*/*");
            connection.setRequestProperty("connection", "Keep-Alive");
            connection.setRequestProperty("user-agent", "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1;SV1)");
            connection.connect();
            in = new BufferedReader(new InputStreamReader(connection.getInputStream(), "UTF-8"));
            String line;
            while ((line = in.readLine()) != null) {
                result += line;
            }
            List<Object> list = JsonUtil.toObjectList(result, Object.class);
            for (Object obj : list) {
                System.out.println(obj.toString());
            }
        } catch (Exception e) {
            System.out.println("12345 workItem find error");
        } finally {
            try {
                if (in != null) {
                    in.close();
                }
            } catch (Exception e2) {
                e2.printStackTrace();
            }
        }
    }
}
