最简单的http请求代码

            URL link = new URL("http://www.sojson.com");
            InputStream is = link.openStream();
            BufferedReader br = new BufferedReader(new     InputStreamReader(is,
                    "utf-8"));
            StringBuilder strBuilder = new StringBuilder();
            String sLine = null;
            while ((sLine = br.readLine()) != null) {
                strBuilder.append(sLine);
                strBuilder.append("\r\n");
            }
            br.close();
            String content = strBuilder.toString();
