以下都是實(shí)戰(zhàn)經(jīng)驗(yàn)：
1、Socket讀取
      String strServer=http://www.google.cn;//這里同樣可以用ip來(lái)訪問(wèn):203.208.35.100
      String strPage="/language_tools?hl=zh-CN";
      try { 
           String hostname = strServer; 
           int port = 80; 
           InetAddress addr = InetAddress.getByName(hostname); 
           Socket socket = new Socket(addr, port);
           BufferedWriter wr = new BufferedWriter(new OutputStreamWriter(socket.getOutputStream(), "UTF8")); 
           wr.write("GET " + strPage + " HTTP/1.0\r\n"); 
           wr.write("HOST:" + strServer + "\r\n"); 
           wr.write("\r\n"); 
           wr.flush();
           BufferedReader rd = new BufferedReader(new InputStreamReader(socket.getInputStream()));
           String line; 
           while ((line = rd.readLine()) != null) { 
                System.out.println(line); 
           }
           wr.close(); 
           rd.close(); 
      } catch (Exception e) { 
           System.out.println(e.toString()); 
      }
2、HttpClient方式
      HttpClient client=new HttpClient();
      GetMethod method=new GetMethod("       int status=client.executeMethod(method);
      if(status==HttpStatus.SC_OK){
       //讀取內(nèi)容
       byte[] responseBody = method.getResponseBody();
       //處理內(nèi)容
       System.out.println(new String(responseBody));
       System.out.println("文件名稱："+method.getPath());
        }
3、HttpURLConnection方式
      URL url = new URL("這里是你要連接的地址");
      HttpURLConnection conn = (HttpURLConnection)url.openConnection();
      conn.setDoOutput(true);//是否可用于輸出(輸出參數(shù))，默認(rèn)為fasle。另:setDoInput()為是否可用于輸入，默認(rèn)為true
      String parameters = "name=admin&password=123456";//這里是要傳遞的參數(shù)
      OutputStream os = conn.getOutputStream();
      os.write(parameters.getBytes("utf-8"));
      os.flush();
      os.close();
      System.out.println("返回狀態(tài)碼："+conn.getResponseCode());
      System.out.println("返回消息："+conn.getResponseMessage());
      InputStream is = conn.getInputStream();
      BufferedReader br = new BufferedReader(new InputStreamReader(is,"utf-8"));
      String line = null;
      while((line=br.readLine())!=null){
       System.out.println(line);
      }
    //  DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();;
    //  DocumentBuilder db = dbf.newDocumentBuilder();
    //  Document doc = db.parse(is);
